Merge tag 'qcom-clk-for-6.4' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into clk-qcom Pull Qualcomm clk driver updates from Bjorn Andersson: New drivers for Global clock controller on SM7150, IPQ9574, MSM8917 and IPQ5332 are added. New GPU clock controllers for SM6115, SM6125, SM6375 and SA8775P are added. The APSS IPQ PLL driver is refactored to support different PLL types, support for the Stromer Plus PLL type is added, and support for IPQ5332 is introduced. Helpers for settings sleep, wake and retain bits of CBCR registers are introduced and used in some of the newly introduced GPU clock drivers. The platform_driver remove callbacks is transitioned to remove_new, as part of the system wide cleanup effort. In the Display clock controller for QCM2290, the MDSS_CORE reset is introduced and the non-existent DSI1PHY clock is removed. IPQ4019 Global clock controller is transitioned to parent_data. USB GDSCs in SM6375, MSM8996 and MSM8998 are changed to use retention as disabled state, to avoid collapsing them during suspend. The CX GDSC in the SM6375 GPU clock controller has it's disable-wait value corrected. QCM2290 SDCC2 src clock moves to floor_ops. The two EMAC GDSCs are added for SC8280XP. Relevant RCGs in the SM6115 Global clock controller are moved to use shared_ops. PCIe PIPE clock operations on SM8350 are updated, to ensure the mux is parked when the parent PLL is disabled. GDSCs are added to the SC7280 LPASS audio clock controller. The RPM clock controller is transitioned to use the managed version of of_clk_add_hw_provider(). Missing XO clocks are added to MSM8226 and MSM8974. DeviceTree bindings are added for the various newly supported clock controllers, the binding for KPSS ACC and GCC drivers are converted to YAML and a few fixes are introduced. * tag 'qcom-clk-for-6.4' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (57 commits) clk: qcom: gcc-sc8280xp: Add EMAC GDSCs clk: qcom: dispcc-qcm2290: Remove inexistent DSI1PHY clk clk: qcom: add the GPUCC driver for sa8775p dt-bindings: clock: qcom: describe the GPUCC clock for SA8775P clk: qcom: gcc-sm8350: fix PCIe PIPE clocks handling clk: qcom: lpassaudiocc-sc7280: Add required gdsc power domain clks in lpass_cc_sc7280_desc clk: qcom: lpasscc-sc7280: Skip qdsp6ss clock registration dt-bindings: clock: qcom,sc7280-lpasscc: Add qcom,adsp-pil-mode property clk: qcom: rpm: Use managed `of_clk_add_hw_provider()` clk: qcom: Add Global Clock Controller driver for IPQ9574 dt-bindings: clock: Add ipq9574 clock and reset definitions clk: qcom: gpucc-sm6375: Configure CX_GDSC disable wait value clk: qcom: gcc-sm6115: Mark RCGs shared where applicable clk: qcom: dispcc-qcm2290: Add MDSS_CORE reset dt-bindings: clock: dispcc-qcm2290: Add MDSS_CORE reset clk: qcom: apss-ipq-pll: add support for IPQ5332 dt-bindings: clock: qcom,a53pll: add IPQ5332 compatible clk: qcom: apss-ipq-pll: refactor the driver to accommodate different PLL types dt-bindings: mailbox: qcom,apcs-kpss-global: fix SDX55 'if' match dt-bindings: mailbox: qcom,apcs-kpss-global: correct SDX55 clocks ...

On SM8350 platform the PCIe PIPE clocks require additional handling to function correctly. They are to be switched to the tcxo source before turning PCIe GDSCs off and should be switched to PHY PIPE source once they are working. Switch PCIe PHY clocks to use clk_regmap_phy_mux_ops, which provide support for this dance. Fixes: 44c20c9e ("clk: qcom: gcc: Add clock driver for SM8350") Signed-off-by:

The qdsp6ss memory region is being shared by ADSP remoteproc device and lpasscc clock device, hence causing memory conflict. To avoid this, when qdsp6ss clocks are being enabled in remoteproc driver, skip qdsp6ss clock registration if "qcom,adsp-pil-mode" is enabled and also assign max_register value.

When this property is set, the remoteproc is used to boot the LPASS and therefore qdsp6ss clocks would be used to bring LPASS out of reset, hence they are directly controlled by the remoteproc. This is a cleanup done to handle overlap of regmap of lpasscc and adsp remoteproc blocks. Signed-off-by:

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. 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 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:
