+Subject: [PATCH 02/70] MIPS: lantiq: reorganize xway code
+
+Inside the folder arch/mips/lantiq/xway, there were alot of small files with
+lots of duplicated code. This patch adds a wrapper function for inserting and
+requesting resources and unifies the small files into one bigger file.
+
+This patch makes the xway code consistent with the falcon support added later
+in this series.

+Subject: [PATCH 03/70] MIPS: lantiq: change ltq_request_gpio() call signature
+
+ltq_request_gpio() was using alt0/1 to multiplex the function of GPIO pins.
+This was XWAY specific. In order to also accomodate SoCs that require more bits
+we use a 32bit mask instead. This way the call signature is consistent between
+XWAY and FALC-ON.

+Subject: [PATCH 08/70] MIPS: lantiq: fix early printk
+
+The code was using a 32bit write operations in the early_printk code. This
+resulted in 3 zero bytes also being written to the serial port. This patch
+changes the memory access to 8bit.

+Subject: [PATCH 15/70] NET: MIPS: lantiq: make etop ethernet work on ase/ar9
+
+Extend the driver to handle the different DMA channel layout for AR9 and
+Amazon-SE SoCs. The patch also adds support for the integrated PHY found
+on Amazon-SE and the gigabit switch found inside the AR9.

+Subject: [PATCH 16/70] NET: MIPS: lantiq: non existing phy was not handled
+ gracefully
+
+The code blindly assumed that that a PHY device was present causing a BadVA.
+In addition the driver should not fail to load incase no PHY was found.
+Instead we print the following line and continue with no attached PHY.
+
+   etop: mdio probe failed

+
+3.2 introduced devm_request_gpio() to allow managed gpios.
+
+The devres api requires a struct device pointer to work. Add a parameter to ltq_gpio_request()

+On Falcon SoCs we have a secondary serial port that can be used to help
+debug the voice core. For the port to work several clocking bits need to
+be activated. We convert the code to clkdev api.

+Subject: [PATCH 35/70] SPI: MIPS: lantiq: add FALC-ON spi driver
+
+The external bus unit (EBU) found on the FALC-ON SoC has spi emulation that is
+designed for serial flash access. This driver has only been tested with m25p80
+type chips. The hardware has no support for other types of spi peripherals.

+Subject: [PATCH 37/70] MIPS: lantiq: add xway nand driver
+
+This patch adds a nand driver for XWAY SoCs. The patch makes use of the
+plat_nand driver. As with the EBU NOR driver merged in 3.0, we have the
+endianess swap problem on read. To workaround this problem we make the
+read_byte() callback available via the plat_nand driver causing the nand
+layer to do byte reads.

++ * The Core Interface Layer provides basic services for accessing and
++ * managing the DWC_otg hardware. These services are used by both the
++ * Host Controller Driver and the Peripheral Controller Driver.
++ *
++ * The CIL manages the memory map for the core so that the HCD and PCD
++ * don't have to do this separately. It also handles basic tasks like
++ * reading/writing the registers and data FIFOs in the controller.
++ * Some of the data access functions provide encapsulation of several
++ * operations required to perform a task, such as writing multiple
++ * registers to start a transfer. Finally, the CIL performs basic
++ * services that are not specific to either the host or device modes
++ * of operation. These services include management of the OTG Host
++ * Negotiation Protocol (HNP) and Session Request Protocol (SRP). A
++ * Diagnostic API is also provided to allow testing of the controller
++ * hardware.
++ *
++ * The Core Interface Layer has the following requirements:
++ * - Provides basic controller operations.
++ * - Minimal use of OS services.  
++ * - The OS services used will be abstracted by using inline functions
++ *   or macros.

++/** @file
++ * The dwc_otg_driver module provides the initialization and cleanup entry
++ * points for the DWC_otg driver. This module will be dynamically installed
++ * after Linux is booted using the insmod command. When the module is
++ * installed, the dwc_otg_init function is called. When the module is
++ * removed (using rmmod), the dwc_otg_cleanup function is called.
++ * 
++ * This module also defines a data structure for the dwc_otg_driver, which is
++ * used in conjunction with the standard ARM lm_device structure. These
++ * structures allow the OTG driver to comply with the standard Linux driver
++ * model in which devices and drivers are registered with a bus driver. This
++ * has the benefit that Linux can expose attributes of the driver and device
++ * in its special sysfs file system. Users can then read or write files in
++ * this file system to perform diagnostics on the driver components or the
++ * device.

++/**
++ * @file
++ *
++ * This file contains the data structures for accessing the DWC_otg core registers.
++ *
++ * The application interfaces with the HS OTG core by reading from and
++ * writing to the Control and Status Register (CSR) space through the
++ * AHB Slave interface. These registers are 32 bits wide, and the
++ * addresses are 32-bit-block aligned.
++ * CSRs are classified as follows:
++ * - Core Global Registers
++ * - Device Mode Registers
++ * - Device Global Registers
++ * - Device Endpoint Specific Registers
++ * - Host Mode Registers
++ * - Host Global Registers
++ * - Host Port CSRs
++ * - Host Channel Specific Registers
++ *
++ * Only the Core Global registers can be accessed in both Device and
++ * Host modes. When the HS OTG core is operating in one mode, either
++ * Device or Host, the application must not access registers from the
++ * other mode. When the core switches from one mode to another, the
++ * registers in the new mode of operation must be reprogrammed as they
++ * would be after a power-on reset.

++ **
++ **                     The Host Controller Driver (HCD) is responsible for translating requests

++   \brief This function trigger a data transfer for a host channel and

++
++  For a PING transfer in Slave mode, the Do Ping bit is set in the HCTSIZ
++  register along with a packet count of 1 and the channel is enabled. This
++  causes a single PING transaction to occur. Other fields in HCTSIZ are
++  simply set to 0 since no data transfer occurs in this case.
++
++  For a PING transfer in DMA mode, the HCTSIZ register is initialized with
++  all the information required to perform the subsequent data transfer. In
++  addition, the Do Ping bit is set in the HCTSIZ register. In this case, the
++  controller performs the entire PING protocol, then starts the data
++  transfer.
++  \param _core_if        Pointer of core_if structure
++  \param _ifxhc Information needed to initialize the host channel. The xfer_len
++  value may be reduced to accommodate the max widths of the XferSize and
++  PktCnt fields in the HCTSIZn register. The multi_count value may be changed

++ \brief A URB Descriptor (URBD) holds the state of a bulk, control,
++  interrupt, or isochronous transfer. A single URBD is created for each URB
++  (of one of these types) submitted to the HCD. The transfer associated with
++  a URBD may require one or multiple transactions.
++
++  A URBD is linked to a EP Queue Head, which is entered in either the
++  isoc, intr or non-periodic schedule for execution. When a URBD is chosen for
++  execution, some or all of its transactions may be executed. After
++  execution, the state of the URBD is updated. The URBD may be retired if all
++  its transactions are complete or if an error occurred. Otherwise, it
++  remains in the schedule so more transactions can be executed later.

++  Slave mode, the caller must ensure that there is sufficient space in the
++  request queue and Tx Data FIFO.
++
++  For an OUT transfer in Slave mode, it loads a data packet into the
++  appropriate FIFO. If necessary, additional data packets will be loaded in
++  the Host ISR.
++
++  For an IN transfer in Slave mode, a data packet is requested. The data
++  packets are unloaded from the Rx FIFO in the Host ISR. If necessary,
++  additional data packets are requested in the Host ISR.
++
++  For a PING transfer in Slave mode, the Do Ping bit is set in the HCTSIZ
++  register along with a packet count of 1 and the channel is enabled. This
++  causes a single PING transaction to occur. Other fields in HCTSIZ are
++  simply set to 0 since no data transfer occurs in this case.
++
++  For a PING transfer in DMA mode, the HCTSIZ register is initialized with
++  all the information required to perform the subsequent data transfer. In
++  addition, the Do Ping bit is set in the HCTSIZ register. In this case, the
++  controller performs the entire PING protocol, then starts the data
++  transfer.
++
++  @param _ifxhc Information needed to initialize the host channel. The xfer_len

++ **   DESCRIPTION     : This file contains the data structures for accessing the IFXUSB core
++ **                     registers.
++ **                     The application interfaces with the USB core by reading from and
++ **                     writing to the Control and Status Register (CSR) space through the
++ **                     AHB Slave interface. These registers are 32 bits wide, and the
++ **                     addresses are 32-bit-block aligned.
++ **                     CSRs are classified as follows:
++ **                     - Core Global Registers
++ **                     - Device Mode Registers
++ **                     - Device Global Registers
++ **                     - Device Endpoint Specific Registers
++ **                     - Host Mode Registers
++ **                     - Host Global Registers
++ **                     - Host Port CSRs
++ **                     - Host Channel Specific Registers
++ **
++ **                     Only the Core Global registers can be accessed in both Device and
++ **                     Host modes. When the USB core is operating in one mode, either
++ **                     Device or Host, the application must not access registers from the
++ **                     other mode. When the core switches from one mode to another, the
++ **                     registers in the new mode of operation must be reprogrammed as they
++ **                     would be after a power-on reset.

+Subject: [PATCH 52/70] MIPS: lantiq: make GPIO3 work on AR9
+
+There are 3 16bit and 1 8bit gpio ports on AR9. The gpio driver needs a hack
+at 2 places to make the different register layout of the GPIO3 work properly
+with the driver. Before only GPIO0-2 were supported. As the GPIO number scheme
+clashes with the new size, we also move the other gpio chips to new offsets.

++	  IFX extension for reserving (splitting) cache ways among VPEs. You must
++	  give kernel command line arguments vpe_icache_shared=0 or
++	  vpe_dcache_shared=0 to enable splitting of icache or dcache
++	  respectively. Then you can specify which cache ways should be
++	  assigned to which VPE. There are total 8 cache ways, 4 each
++	  for dcache and icache: dcache_way0, dcache_way1,dcache_way2,
++	  dcache_way3 and icache_way0,icache_way1, icache_way2,icache_way3.
++
++	  For example, if you specify vpe_icache_shared=0 and icache_way2=1,
++	  then the 3rd icache way will be assigned to VPE0 and denied in VPE1.
++
++	  For icache, software is required to make at least one cache way available
++	  for a VPE at all times i.e., one can't assign all the icache ways to one
++	  VPE.
++
++	  By default, vpe_dcache_shared and vpe_icache_shared are set to 1
++	  (i.e., both icache and dcache are shared among VPEs)
