ipq806x: Add support for linux-4.4
1)Changes - Rebased the patches for linux-4.4.7 - Added patch to fix spi nor fifo and dma support - Added patch to configure watchdog barktime 2)Testing Tested on IPQ AP148 Board: a. NOR boot and NAND boot b. ethernet network and ath10k wifi c. ubi sysupgrade UnTested dwc3 usb has not been validated on IPQ board(AP148) 3)Known Issues: Once we flash ubi image on AP148, and if we reset the board, uboot on first boot creates PEB and LEB for dynamic sized partitions, which is incorrect and not what linux expects which causes errors when trying to mount rootfs. In order to test this, we can use the below steps: a. Flash the ubi image on board and don't reset the board b. load the kernel fit image in RAM and boot from there.

-This patch adds DMA capabilities to the spi-qup driver. If DMA channels are
-present, the QUP will use DMA instead of block mode for transfers to/from SPI
-peripherals for transactions larger than the length of a block.

-
-This patch fixes a number of errors with the QUP block transfer mode. Errors
-manifested themselves as input underruns, output overruns, and timed out
-transactions.
-
-The block mode does not require the priming that occurs in FIFO mode. At the
-moment that the QUP is placed into the RUN state, the QUP will immediately raise
-an interrupt if the request is a write. Therefore, there is no need to prime
-the pump.
-
-In addition, the block transfers require that whole blocks of data are
-read/written at a time. The last block of data that completes a transaction may
-contain less than a full blocks worth of data.
-
-Each block of data results in an input/output service interrupt accompanied with
-a input/output block flag set. Additional block reads/writes require clearing
-of the service flag. It is ok to check for additional blocks of data in the
-ISR, but you have to ack every block you transfer. Imbalanced acks result in
-early return from complete transactions with pending interrupts that still have
-to be ack'd. The next transaction can be affected by these interrupts.
-Transactions are deemed complete when the MAX_INPUT or MAX_OUTPUT flag are set.
-
-Changes from v2:
-- Added in additional completion check so that transaction done is not
- prematurely signaled.
-- Fixed various review comments.
-
-Changes from v1:
-- Split out read/write block function.
-- Removed extraneous checks for transfer length
-

-Subject: [PATCH] spi: qup: Ensure done detection
-
-This patch fixes an issue where a SPI transaction has completed, but the done
-condition is missed. This occurs because at the time of interrupt the
-MAX_INPUT_DONE_FLAG is not asserted. However, in the process of reading blocks
-of data from the FIFO, the last portion of data comes in.
-
-The opflags read at the beginning of the irq handler no longer matches the
-current opflag state. To get around this condition, the block read function
-should update the opflags so that done detection is correct after the return.
-

-Subject: [PATCH 1/3] watchdog: qcom: use timer devicetree binding
-
-MSM watchdog configuration happens in the same register block as the
-timer, so we'll use the same binding as the existing timer.
-
-The qcom-wdt will now be probed when devicetree has an entry compatible
-with "qcom,kpss-timer" or "qcom-scss-timer".

-+ * The Qualcomm shared memory system is a allocate only heap structure that
-+ * consists of one of more memory areas that can be accessed by the processors
-+ * in the SoC.
-+ *
-+ * All systems contains a global heap, accessible by all processors in the SoC,
-+ * with a table of contents data structure (@smem_header) at the beginning of
-+ * the main shared memory block.
-+ *
-+ * The global header contains metadata for allocations as well as a fixed list
-+ * of 512 entries (@smem_global_entry) that can be initialized to reference
-+ * parts of the shared memory space.
-+ *
-+ *
-+ * In addition to this global heap a set of "private" heaps can be set up at
-+ * boot time with access restrictions so that only certain processor pairs can
-+ * access the data.
-+ *
-+ * These partitions are referenced from an optional partition table
-+ * (@smem_ptable), that is found 4kB from the end of the main smem region. The
-+ * partition table entries (@smem_ptable_entry) lists the involved processors
-+ * (or hosts) and their location in the main shared memory region.
-+ *
-+ * Each partition starts with a header (@smem_partition_header) that identifies
-+ * the partition and holds properties for the two internal memory regions. The
-+ * two regions are cached and non-cached memory respectively. Each region
-+ * contain a link list of allocation headers (@smem_private_entry) followed by
-+ * their data.
-+ *
-+ * Items in the non-cached region are allocated from the start of the partition
-+ * while items in the cached region are allocated from the end. The free area
-+ * is hence the region between the cached and non-cached offsets.
-+ *
-+ *
-+ * To synchronize allocations in the shared memory heaps a remote spinlock must
-+ * be held - currently lock number 3 of the sfpb or tcsr is used for this on all
-+ * platforms.

-
-SMEM is used on IPQ806x to store various board related information such
-as boot device and flash partition layout. We'll declare it as a device
-so we can make use of it thanks to the new SMEM soc driver.

-Subject: [PATCH 3/3] mtd: add SMEM parser for QCOM platforms
-
-On QCOM platforms using MTD devices storage (such as IPQ806x), SMEM is
-used to store partition layout. This new parser can now be used to read
-SMEM and use it to register an MTD layout according to its content.

-Subject: [PATCH 9/9] ARM: qcom: automatically select PCI_DOMAINS if PCI is
- enabled
-
-If multiple PCIe devices are present in the system, the kernel will
-panic at boot time when trying to scan the PCI buses. This happens on
-IPQ806x based platforms, which has 3 PCIe ports.
-
-Enabling this option allows the kernel to assign the pci-domains
-according to the device-tree content. This allows multiple PCIe
-controllers to coexist in the system.

-so theoretically multiple parents could be enabled at the same time, but in
-practice only one bit should ever be 1. So to select parent 0, set
-the register (*) to 0x01, to select parent 1 set it 0x02, parent 2, 0x04,
-parent 3, 0x08, etc.
-
-But the current code does:
-
- if (mux->flags & CLK_MUX_INDEX_BIT)
- index = (1 << ffs(index));
-
-Which means that:
-
-For an input index of 0, ffs returns 0, so we set the register
-to 0x01, ok.
-
-For an input index of 1, ffs returns 1, so we set the register
-to 0x02, ok.
-
-For an input index of 2, ffs returns 2, so we set the register
-to 0x04, ok.
-
-For an input index of 3, ffs returns 1, so we set the register
-to 0x02, not good!
-
-The code should simply be:
-
- if (mux->flags & CLK_MUX_INDEX_BIT)
- index = 1 << index;
-
-Which always does the right thing, this commit fixes this.

-Subject: [PATCH] clk: Add __clk_mux_determine_rate_closest
-
-Some clock drivers want to find the closest rate on the input of
-a mux instead of a rate that's less than or equal to the desired
-rate. Add a generic mux function to support this.

- leak
-
-The common clk_register_{divider,gate,mux} functions allocated memory
-for internal data which wasn't freed anywhere. Drivers using these
-helpers could only unregister clocks but the memory would still leak.
-
-Add corresponding unregister functions which will release all resources.

-Krait CPUs have a handful of L2 cache controller registers that
-live behind a cp15 based indirection register. First you program
-the indirection register (l2cpselr) to point the L2 'window'
-register (l2cpdr) at what you want to read/write. Then you
-read/write the 'window' register to do what you want. The
-l2cpselr register is not banked per-cpu so we must lock around
-accesses to it to prevent other CPUs from re-pointing l2cpdr
-underneath us.

-We want to reuse the logic in clk-mux.c for other clock drivers
-that don't use readl as register accessors. Fortunately, there
-really isn't much to the mux code besides the table indirection
-and quirk flags if you assume any bit shifting and masking has
-been done already. Pull that logic out into reusable functions
-that operate on an optional table and some flags so that other
-drivers can use the same logic.

-If a clock is on and we call clk_set_rate() on it we may get into
-a situation where the clock temporarily increases in rate
-dramatically while we walk the tree and call .set_rate() ops. For
-example, consider a case where a PLL feeds into a divider.
-Initially the divider is set to divide by 1 and the PLL is
-running fairly slow (100MHz). The downstream consumer of the
-divider output can only handle rates =< 400 MHz, but the divider
-can only choose between divisors of 1 and 4.
-
- +-----+ +----------------+
- | PLL |-->| div 1 or div 4 |---> consumer device
- +-----+ +----------------+
-
-To achieve a rate of 400MHz on the output of the divider, we
-would have to set the rate of the PLL to 1.6 GHz and then divide
-it by 4. The current code would set the PLL to 1.6GHz first while
-the divider is still set to 1, thus causing the downstream
-consumer of the clock to receive a few clock cycles of 1.6GHz
-clock (far beyond it's maximum acceptable rate). We should be
-changing the divider first before increasing the PLL rate to
-avoid this problem.
-
-Therefore, set the rate of any child clocks that are increasing
-in rate from their current rate so that they can increase their
-dividers if necessary. We assume that there isn't such a thing as
-minimum rate requirements.

-Sometimes clocks can't accept their parent source turning off
-while the source is reprogrammed to a different rate. Most
-notably CPU clocks require a way to switch away from the current
-PLL they're running on, reprogram that PLL to a new rate, and
-then switch back to the PLL with the new rate once they're done.
-Add a hook that drivers can implement allowing them to return a
-'safe parent' that they can switch their parent to while the
-upstream source is reprogrammed to support this.

-This patch is good enough for Krait, but soon I'll need to
-support a "safe rate" where we ask a clock what rate it needs to be running
-at to be sure it's within voltage constraints. Right now safe parent
-handles that problem on Krait, but on other platforms it won't work.

-Subject: [PATCH] FROMLIST: cpufreq: Add a cpufreq-krait based on cpufreq-cpu0
-
-Krait processors have individual clocks for each CPU that can
-scale independently from one another. cpufreq-cpu0 is fairly
-close to this, but assumes that there is only one clock for all
-CPUs. Add a driver to support the Krait configuration.
-
-TODO: Merge into cpufreq-cpu0? Or make generic?

-Subject: [PATCH] dmaengine: Remove the need to declare device_control
-
-In order to migrate the drivers without triggering a BUG_ON for the converted
-drivers, which would cause bisectability issues, we need to remove that check
-before removing the device_control function entirely.

-
-Nowadays, some drivers don't have anything in there channel allocation
-callbacks anymore.
-
-Remove the BUG_ON if those callbacks aren't implemented, in order to allow

-Subject: [PATCH] dmaengine: Introduce a device_config callback
-
-The fact that the channel configuration is done in device_control is rather
-misleading, since it's not really advertised as such, plus, the fact that the
-framework exposes a function of its own makes it not really intuitive, while
-we're losing the type checking whenever we pass that unsigned long argument.
-
-Add a device_config callback to dma_device, with a fallback on the old
-behaviour for now for existing drivers to opt in.

-
-Split out the terminate_all command from device_control to a dma_device
-callback. In order to preserve backward capability, still rely on
-device_control if no such callback has been implemented.
-
-Eventually, this will allow to create a generic dma_slave_caps callback.

-Add the DMA engine driver for the QCOM Application Data Mover (ADM) DMA
-controller found in the MSM8x60 and IPQ/APQ8064 platforms.
-
-The ADM supports both memory to memory transactions and memory
-to/from peripheral device transactions. The controller also provides flow
-control capabilities for transactions to/from peripheral devices.
-
-The initial release of this driver supports slave transfers to/from peripherals
-and also incorporates CRCI (client rate control interface) flow control.

-Subject: [PATCH] clk: qcom: Add EBI2 clocks for IPQ806x
-
-The NAND controller within EBI2 requires EBI2_CLK and
-EBI2_ALWAYS_ON_CLK clocks. Create structs for these clocks so
-that they can be used by the NAND controller driver. Add an entry
-for EBI2_AON_CLK in the gcc-ipq806x DT binding document.

-
-The Qualcomm NAND controller is found in SoCs like IPQ806x, MSM7xx,
-MDM9x15 series.
-
-It exists as a sub block inside the IPs EBI2 (External Bus Interface 2)
-and QPIC (Qualcomm Parallel Interface Controller). These IPs provide a
-broader interface for external slow peripheral devices such as LCD and
-NAND/NOR flash memory or SRAM like interfaces.
-
-We add support for the NAND controller found within EBI2. For the SoCs
-of our interest, we only use the NAND controller within EBI2. Therefore,
-it's safe for us to assume that the NAND controller is a standalone block
-within the SoC.
-
-The controller supports 512B, 2kB, 4kB and 8kB page 8-bit and 16-bit NAND
-flash devices. It contains a HW ECC block that supports BCH ECC (4, 8 and
-16 bit correction/step) and RS ECC(4 bit correction/step) that covers main
-and spare data. The controller contains an internal 512 byte page buffer
-to which we read/write via DMA. The EBI2 type NAND controller uses ADM DMA
-for register read/write and data transfers. The controller performs page
-reads and writes at a codeword/step level of 512 bytes. It can support up
-to 2 external chips of different configurations.
-
-The driver prepares register read and write configuration descriptors for
-each codeword, followed by data descriptors to read or write data from the
-controller's internal buffer. It uses a single ADM DMA channel that we get
-via dmaengine API. The controller requires 2 ADM CRCIs for command and
-data flow control. These are passed via DT.
-
-The ecc layout used by the controller is syndrome like, but we can't use
-the standard syndrome ecc ops because of several reasons. First, the amount
-of data bytes covered by ecc isn't same in each step. Second, writing to
-free oob space requires us writing to the entire step in which the oob
-lies. This forces us to create our own ecc ops.
-
-One more difference is how the controller accesses the bad block marker.
-The controller ignores reading the marker when ECC is enabled. ECC needs
-to be explicity disabled to read or write to the bad block marker. For
-this reason, we use the newly created flag NAND_BBT_ACCESS_BBM_RAW to
-read the factory provided bad block markers.
-
-v3:
-- Refactor dma functions for maximum reuse
-- Use dma_slave_confing on stack
-- optimize and clean upempty_page_fixup using memchr_inv
-- ensure portability with dma register reads using le32_* funcs
-- use NAND_USE_BOUNCE_BUFFER instead of doing it ourselves
-- fix handling of return values of dmaengine funcs
-- constify wherever possible
-- Remove dependency on ADM DMA in Kconfig
-- Misc fixes and clean ups
-
-v2:
-- Use new BBT flag that allows us to read BBM in raw mode
-- reduce memcpy-s in the driver
-- some refactor and clean ups because of above changes

-Subject: [PATCH] hwspinlock/core: add device tree support
-
-This patch adds a new OF-friendly API of_hwspin_lock_get_id()
-for hwspinlock clients to use/request locks from a hwspinlock
-device instantiated through a device-tree blob. This new API
-can be used by hwspinlock clients to get the id for a specific
-lock using the phandle + args specifier, so that it can be
-requested using the available hwspin_lock_request_specific()
-API.

-msb of the regmap_field was mistakenly given the value 32, to set all bits

-+ * The Qualcomm shared memory system is a allocate only heap structure that
-+ * consists of one of more memory areas that can be accessed by the processors
-+ * in the SoC.
-+ *
-+ * All systems contains a global heap, accessible by all processors in the SoC,
-+ * with a table of contents data structure (@smem_header) at the beginning of
-+ * the main shared memory block.
-+ *
-+ * The global header contains metadata for allocations as well as a fixed list
-+ * of 512 entries (@smem_global_entry) that can be initialized to reference
-+ * parts of the shared memory space.
-+ *
-+ *
-+ * In addition to this global heap a set of "private" heaps can be set up at
-+ * boot time with access restrictions so that only certain processor pairs can
-+ * access the data.
-+ *
-+ * These partitions are referenced from an optional partition table
-+ * (@smem_ptable), that is found 4kB from the end of the main smem region. The
-+ * partition table entries (@smem_ptable_entry) lists the involved processors
-+ * (or hosts) and their location in the main shared memory region.
-+ *
-+ * Each partition starts with a header (@smem_partition_header) that identifies
-+ * the partition and holds properties for the two internal memory regions. The
-+ * two regions are cached and non-cached memory respectively. Each region
-+ * contain a link list of allocation headers (@smem_private_entry) followed by
-+ * their data.
-+ *
-+ * Items in the non-cached region are allocated from the start of the partition
-+ * while items in the cached region are allocated from the end. The free area
-+ * is hence the region between the cached and non-cached offsets.
-+ *
-+ *
-+ * To synchronize allocations in the shared memory heaps a remote spinlock must

-Sometimes clocks can't accept their parent source turning off
-while the source is reprogrammed to a different rate. Most
-notably CPU clocks require a way to switch away from the current
-PLL they're running on, reprogram that PLL to a new rate, and
-then switch back to the PLL with the new rate once they're done.
-Add a hook that drivers can implement allowing them to return a
-'safe parent' that they can switch their parent to while the
-upstream source is reprogrammed to support this.

-This patch is good enough for Krait, but soon I'll need to
-support a "safe rate" where we ask a clock what rate it needs to be running
-at to be sure it's within voltage constraints. Right now safe parent
-handles that problem on Krait, but on other platforms it won't work.

-This patch removes the crci information from the dma channel property. At least
-one client device requires using more than one CRCI value for a channel. This
-does not match the current binding and the crci information needs to be removed.
-
-Instead, the client device will provide this information via other means.

-Some controllers can access the factory bad block marker from OOB only
-when they read it in raw mode. When ECC is enabled, these controllers
-discard reading/writing bad block markers, preventing access to them
-altogether.
-
-The bbt driver assumes MTD_OPS_PLACE_OOB when scanning for bad blocks.
-This results in the nand driver's ecc->read_oob() op to be called, which
-works with ECC enabled.
-
-Create a new BBT option flag that tells nand_bbt to force the mode to
-MTD_OPS_RAW. This would result in the correct op being called for the
-underlying nand controller driver.

-Subject: [PATCH] HACK: arch: arm: force ZRELADDR on arch-qcom
-
-ARCH_QCOM is using the ARCH_MULTIPLATFORM option, as now recommended
-on most ARM architectures. This automatically calculate ZRELADDR by
-masking PHYS_OFFSET with 0xf8000000.
-
-However, on IPQ806x, the first ~20MB of RAM is reserved for the hardware
-network accelerators, and the bootloader removes this section from the
-layout passed from the ATAGS (when used).
-
-For newer bootloader, when DT is used, this is not a problem, we just
-reserve this memory in the device tree. But if the bootloader doesn't
-have DT support, then ATAGS have to be used. In this case, the ARM
-decompressor will position the kernel in this low mem, which will not be
-in the RAM section mapped by the bootloader, which means the kernel will
-freeze in the middle of the boot process trying to map the memory.
-
-As a work around, this patch allows disabling AUTO_ZRELADDR when
-ARCH_QCOM is selected. It makes the zImage usage possible on bootloaders
-which don't support device-tree, which is the case on certain early
-IPQ806x based designs.

+Subject: [PATCH] mtd: add SMEM parser for QCOM platforms
On QCOM platforms using MTD devices storage (such as IPQ806x), SMEM is
used to store partition layout. This new parser can now be used to read
SMEM and use it to register an MTD layout according to its content.

+Subject: [PATCH] clk: Add safe switch hook
+
+Sometimes clocks can't accept their parent source turning off
+while the source is reprogrammed to a different rate. Most
+notably CPU clocks require a way to switch away from the current
+PLL they're running on, reprogram that PLL to a new rate, and
+then switch back to the PLL with the new rate once they're done.
+Add a hook that drivers can implement allowing them to return a
+'safe parent' that they can switch their parent to while the
+upstream source is reprogrammed to support this.

+Subject: [PATCH 2/2] watchdog: qcom: set WDT_BARK_TIME register offset to one
+ second less of bite time
+
+Currently WDT_BARK_TIME register offset is not configured with bark
+timeout during wdt_start,and it is taking bark timeout's default value.
+For some versions of TZ (secure mode) will consider a BARK the same
+as BITE and reset the board.
+
+So instead let's just configure the BARK time to be less than a second
+of the bite timeout so the board does not reset in this scenario
