IPQ5332 APSS PLL is of type Stromer Plus. Add support for the same. To configure the stromer plus PLL separate API (clock_stromer_pll_configure) to be used. To achieve this, introduce the new member pll_type in device data structure and call the appropriate function based on this.

APSS PLL found on the IPQ8074 and IPQ6018 are of type Huayra PLL. But, IPQ5332 APSS PLL is of type Stromer Plus. To accommodate both these PLLs, refactor the driver to take the clk_alpha_pll, alpha_pll_config via driver data.

2023-03-21clk: qcom: gcc-msm8998: Update the .pwrsts for usb gdscKonrad Dybcio
The USB controller on msm8998 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.

2023-03-16clk: renesas: Convert to platform remove callback returning voidUwe Kleine-König
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.

2023-03-13clk: qcom: clk-hfpll: switch to .determine_rateLuca Weiss
.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).

2023-03-13clk: qcom: branch: Add helper functions for setting SLEEP/WAKE bitsKonrad Dybcio
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.

2023-03-13clk: qcom: branch: Add helper functions for setting retain bitsKonrad Dybcio
Most Qualcomm branch clocks come with a pretty usual set of bits that can enable memory retention by means of not turning off parts of the memory logic. Add them to the common header file and introduce helper functions for setting them instead of using magic writes.

2023-03-13clk: mediatek: mt8135: Convert to simple probe and enable module buildAngeloGioacchino Del Regno
Convert the MT8135 clock drivers to platform_driver using the common simple probe mechanism; special note goes to the introduction of dummy clocks with ID 0 (where 0 is the first entry of a clock array) for each clock controller: this was necessary because of a mistake in the bindings for all MT8135 clock controllers, where the first clock has ID 1 (hence, array would start from element 1) instead of zero. Now that all of the MT8135 clock drivers (including apmixedsys) can be compiled as modules, change the COMMON_CLK_MT8135 configuration option to tristate to enable module build. While at it, also remove the __initconst annotation from all of the clock arrays as they are not only used during init anymore, but also during runtime.
