The USB controller on MSM8996 doesn't retain its state when the system goes into low power state and the GDSCs are turned off. This can be observed by the USB connection not coming back alive after putting the device into suspend, essentially breaking USB. Work around this by updating the .pwrsts for the USB GDSCs so they only transition to retention state in low power. This change should be reverted when a proper suspend sequence is implemented in the USB drivers. Signed-off-by:

This driver provides clocks, resets and power domains needed for various components of the MSM8917 SoC and the very similar QM215 SoC. According to [1] in the downstream kernel, the GPU clock has a different source mapping on QM215 (gcc_gfx3d_map vs gcc_gfx3d_map_qm215).

Add a device tree binding to describe clocks, resets and power domains provided by the global clock controller on MSM8917 SoCs and the very similar QM215 SoCs. Add the new compatibles to qcom,gcc-msm8909.yaml. There is no need to create another YAML file because the bindings are identical (MSM8917 GCC requires the same parent clocks as the MSM8909 GCC).

Rework kpss-gcc driver Documentation to yaml Documentation and move it to clock as it's a clock-controller. The current kpss-gcc Documentation have major problems and can't be converted directly. Introduce various changes to the original Documentation. Add #clock-cells additional binding as this clock outputs a static clk named acpu_l2_aux with supported compatible. Only some compatible require and outputs a clock, for the others, set only the reg as a required binding to correctly export the kpss-gcc registers. As the reg is shared also add the required syscon compatible. Signed-off-by:

Convert kpss-acc driver Documentation to yaml. The original Documentation was wrong all along. Fix it while we are converting it. The example was wrong as kpss-acc-v2 should only expose the regs but we don't have any driver that expose additional clocks. The kpss-acc driver is only specific to v1. For this exact reason, split the Documentation to 2 different schema, v1 as clock-controller and v2 for power-manager as per msm-3.10 specification, the exposed regs handle power manager.

Clock framework disables the GPLL4 source since there are no active users for this source currently. Some of the clocks initialized by the bootloaders uses the GPLL4 as the source. Due to this, when the GPLL4 is disabled by the clock framework, system is going for the reboot. To avoid this, mark the GPLL4 as ignore unused so that clock framework doesn't disable it. Once the users of this source is enabled, we can get rid of this flag. Signed-off-by:

.determine_rate is meant to replace .round_rate. The former comes with a benefit which is especially relevant on 32-bit systems: since .determine_rate uses an "unsigned long" (compared to a "signed long" which is used by .round_rate) the maximum value on 32-bit systems increases from 2^31 (or approx. 2.14GHz) to 2^32 (or approx. 4.29GHz).

HLOS-controlled branch clocks on non-ancient Qualcomm platforms feature SLEEP and WAKE fields which can be written to to configure how long the clock hardware should wait internally before being (un)gated. Some very sensitive clocks need to have these values programmed to prevent putting the hardware in a not-exactly-good state. Add definitions of these fields and introduce helpers for setting them inside clock drivers. Reviewed-by:

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:
