Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd: "The clk core gains a new set of APIs that allow drivers to both acquire clks and prepare and enable them at the same time. This also comes with devm support so that drivers can make a single call to get and prepare and enable the clk and have that all undone when their driver is removed. Many folks have requested this feature over the years, but we've had disagreements about how to implement it and if it was worthwhile to encourage drivers to use such an API. Now it's here, so let's see how it goes. I hope that by introducing this API we can identify drivers that would benefit from further consolidation of clk API usage, possibly by moving such logic to the bus layer and out of drivers altogether. Outside of that major API update, we have the usual collection of driver updates. A few new SoCs are supported, mostly Qualcomm and Renesas this time around. Then we have the long tail of non-critical fixes and minor feature additions to various clk drivers. And finally more clk provider migration to struct clk_parent_data, reducing boot times in the process. Summary: Core: - devm helpers for clk_get() + clk_prepare() and clk_enable() New Drivers: - Support for the camera clock controller in Qualcomm SM8450 and the display and gpu clock controllers in Qualcomm SM8350 - Add support for the Renesas RZ/Five SoC Updates: - Various fixes, new clocks and USB GDSCs are introduced for Qualcomm IPQ8074 - Fixes to Qualcomm MSM8939 for issues introduced by inheriting the MSM8916 GCC driver - Support for a new type of voteable GDSCs used by Qualcomm SC8280XP PCIe GDSCs - Qualcomm SC8280XP pipe clocks transitioned to the new phy-mux implementation - Qualcomm MSM8996 GCC, RPM clock driver and some clocks in MSM8994 GCC are migrated to use clk_parent_data - Corrected the topology for Titan (camera) GDSCs on Qualcomm SDM845 and SM8250 - Qualcomm MSM8916 gains more possible frequencies for its GP clocks. - The GCC and tsens handling on Qualcomm MSM8960 is reworked to mimic the design in IPQ8074 to allow the GCC driver to probe earlier. - The regulator based mmcx supply for Qualcomm dispcc and videocc is dropped, as the only upstream target that adapted this interface was transitioned several kernel versions ago - Qualcomm GDSCs found to be enabled at boot will now reflect in the enable count of the supply, as was done with the regulator supplies previously - Correct adc1, nic_media and edma1's parents for NXP i.MX93 - rdiv, mfd values, the return rate in recalc_rate and add more frequencies in the table for fracn-gppll on i.MX - Remove Allwinner workaround logic/compatible in fixed factor code - MediaTek clk driver cleanups - Add reset support to more MediaTek clk drivers - deduplicate Allwinner ccu_clks arrays - Allwinner H6 GPU DFS support - Adjust Allwinner Kconfig to limit choice - Fix initconst confusion on Renesas R-Car Gen4 - Add GPT/POEG (PWM) clocks and resets on Renesas RZ/G2L - Add PFC and WDT clocks and resets on Renesas RZ/V2M - Add thermal, SDHI, Z (CPU core), PCIe, and HSCIF (serial) clocks on Renesas R-Car S4-8" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (124 commits) clk: fixed-factor: Introduce *clk_hw_register_fixed_factor_parent_hw() clk: mux: Introduce devm_clk_hw_register_mux_parent_hws() clk: divider: Introduce devm_clk_hw_register_divider_parent_hw() clk: qcom: gcc-msm8994: use parent_hws for gpll0/4 clk: qcom: clk-rpm: convert to parent_data API dt-bindings: clock: fix wrong clock documentation for qcom,rpmcc clk: qcom: gcc-msm8939: Add missing USB HS system clock frequencies clk: qcom: gcc-msm8939: Add missing MDSS MDP clock frequencies clk: qcom: gcc-msm8939: Add missing CAMSS CPP clock frequencies clk: qcom: gcc-msm8939: Fix venus0_vcodec0_clk frequency definitions clk: qcom: gcc-msm8939: Add missing CAMSS CCI bus clock clk: qcom: gcc-msm8939: Fix weird field spacing in ftbl_gcc_camss_cci_clk clk: qcom: gdsc: Bump parent usage count when GDSC is found enabled clk: qcom: Drop mmcx gdsc supply for dispcc and videocc clk: qcom: fix build error initializer element is not constant clk: sprd: Add dt-bindings include file for UMS512 dt-bindings: clk: sprd: Add bindings for ums512 clock controller clk: sunxi-ng: sun50i: h6: Modify GPU clock configuration to support DFS dt-bindings: clock: qcom,gcc-msm8996: add more GCC clock sources clk: qcom: add support for SM8350 DISPCC ...
