+Subject: [PATCH 31/69] 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 33/69] 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.

+Subject: [PATCH 34/69] ARM: Add Krait L2 register accessor functions
+
+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.

+Subject: [PATCH 35/69] clk: mux: Split out register accessors for reuse
+
+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.

+Subject: [PATCH 36/69] clk: Avoid sending high rates to downstream clocks
+ during set_rate
+
+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.

+Subject: [PATCH 37/69] 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' and 'safe frequency' that they can switch their
+parent to while the upstream source is reprogrammed to support
+this.

+Subject: [PATCH 39/69] clk: qcom: Add HFPLL driver
+
+On some devices (MSM8974 for example), the HFPLLs are
+instantiated within the Krait processor subsystem as separate
+register regions. Add a driver for these PLLs so that we can
+provide HFPLL clocks for use by the system.

+
+The Krait clocks are made up of a series of muxes and a divider
+that choose between a fixed rate clock and dedicated HFPLLs for
+each CPU. Instead of using mmio accesses to remux parents, the
+Krait implementation exposes the remux control via cp15
+registers. Support these clocks.

+Subject: [PATCH 42/69] clk: qcom: Add KPSS ACC/GCC driver
+
+The ACC and GCC regions present in KPSSv1 contain registers to
+control clocks and power to each Krait CPU and L2. For CPUfreq
+purposes probe these devices and expose a mux clock that chooses
+between PXO and PLL8.

+Subject: [PATCH 43/69] clk: qcom: Add Krait clock controller driver
+
+The Krait CPU clocks are made up of a primary mux and secondary
+mux for each CPU and the L2, controlled via cp15 accessors. For
+Kraits within KPSSv1 each secondary mux accepts a different aux
+source, but on KPSSv2 each secondary mux accepts the same aux
+source.

+Subject: [PATCH 47/69] mtd: nand: Create a BBT flag to access bad block
+ markers in raw mode
+
+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 49/69] PM / OPP: Support adjusting OPP voltages at runtime
+
+On some SoCs the Adaptive Voltage Scaling (AVS) technique is
+employed to optimize the operating voltage of a device. At a
+given frequency, the hardware monitors dynamic factors and either
+makes a suggestion for how much to adjust a voltage for the
+current frequency, or it automatically adjusts the voltage
+without software intervention. Add an API to the OPP library for
+the former case, so that AVS type devices can update the voltages
+for an OPP when the hardware determines the voltage should
+change. The assumption is that drivers like CPUfreq or devfreq
+will register for the OPP notifiers and adjust the voltage
+according to suggestions that AVS makes.

+Subject: [PATCH 50/69] OPP: Allow notifiers to call dev_pm_opp_get_{voltage,
+ freq} RCU-free
+
+We pass the dev_pm_opp structure to OPP notifiers but the users
+of the notifier need to surround calls to dev_pm_opp_get_*() with
+RCU read locks to avoid lockdep warnings. The notifier is already
+called with the dev_opp's srcu lock held, so it should be safe to
+assume the devm_pm_opp structure is already protected inside the
+notifier. Update the lockdep check for this.

+
+When the voltage is adjusted, the voltage tolerance is not updated.
+This can lead to situations where the voltage min value is greater
+than the voltage max value. The final result is triggering a BUG()
+in the regulator core.
+Fix this by updating the voltage tolerance values too.

+Subject: [PATCH 54/69] cpufreq-dt: Handle OPP voltage adjust events
+
+On some SoCs the Adaptive Voltage Scaling (AVS) technique is
+employed to optimize the operating voltage of a device. At a
+given frequency, the hardware monitors dynamic factors and either
+makes a suggestion for how much to adjust a voltage for the
+current frequency, or it automatically adjusts the voltage
+without software intervention.
+
+In the former case, an AVS driver will call
+dev_pm_opp_modify_voltage() and update the voltage for the
+particular OPP the CPUs are using. Add an OPP notifier to
+cpufreq-dt so that we can adjust the voltage of the CPU when AVS
+updates the OPP.

+Subject: [PATCH 57/69] clk: qcom: Add regmap mux-div clocks support
+
+Add support for hardware that can switch both parent clocks and divider
+at the same time. This avoids generating intermediate frequencies from
+either the old parent clock and new divider or new parent clock and
+old divider combinations.

+Subject: [PATCH 58/69] clk: qcom: Always add factor clock for xo clocks
+
+Currently the RPM/RPM-SMD clock drivers do not register the xo clocks,
+so we should always add factor clock. When we later add xo clocks support
+into the drivers, we should update this function to skip registration.
+By doing so we avoid any DT dependencies.
