Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd: "It looks like a smaller batch of clk updates this time around. In the core framework we just have some minor tweaks and a debugfs feature, so not much to see there. The driver updates are fairly well split between AT91 and Qualcomm clk support. Adding those two drivers together equals about 50% of the diffstat. Otherwise, the big amount of work this time was on supporting Broadcom's Raspberry Pi firmware clks. Highlights: Core: - Document clk_hw_round_rate() so it gets some more use - Remove unused __clk_get_flags() - Add a prepare/enable debugfs feature similar to rate setting New Drivers: - Add support for SAMA7G5 SoC clks - Enable CPU clks on Qualcomm IPQ6018 SoCs - Enable CPU clks on Qualcomm MSM8996 SoCs - GPU clk support for Qualcomm SM8150 and SM8250 SoCs - Audio clks on Qualcomm SC7180 SoCs - Microchip Sparx5 DPLL clk - Add support for the new Renesas RZ/G2H (R8A774E1) SoC Updates: - Make defines for bcm63xx-gate clks to use in DT - Support BCM2711 SoC firmware clks - Add HDMI clks for BCM2711 SoCs - Add RTC related clks on Ingenic SoCs - Support USB PHY clks on Ingenic SoCs - Support gate clks on BCM6318 SoCs - RMU and DMAC/GPIO clock support for Actions Semi S500 SoCs - Use poll_timeout functions in Rockchip clk driver - Support Rockchip rk3288w SoC variant - Mark mac_lbtest critical on Rockchip rk3188 - Add CAAM clock support for i.MX vf610 driver - Add MU root clock support for i.MX imx8mp driver - Amlogic g12: add neural network accelerator clock sources - Amlogic meson8: remove critical flag for main PLL divider - Amlogic meson8: add video decoder clock gates - Convert one more Renesas DT binding to json-schema - Enhance critical clock handling on Renesas platforms to only consider clocks that were enabled at boot time" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (79 commits) clk: qcom: gcc: Make disp gpll0 branch aon for sc7180/sdm845 ipq806x: gcc: add support for child probe clk: qcom: msm8996: Make symbol 'cpu_msm8996_clks' static clk: qcom: ipq8074: Add correct index for PCIe clocks clk: <linux/clk-provider.h>: drop a duplicated word clk: renesas: cpg-mssr: Add r8a774e1 support dt-bindings: clock: renesas,cpg-mssr: Document r8a774e1 clk: Drop duplicate selection in Kconfig clk: qcom: smd: Add support for MSM8992/4 rpm clocks clk: qcom: ipq8074: Add missing clocks for pcie dt-bindings: clock: qcom: ipq8074: Add missing bindings for PCIe Replace HTTP links with HTTPS ones: Common CLK framework clk: qcom: Add CPU clock driver for msm8996 dt-bindings: clk: qcom: Add bindings for CPU clock for msm8996 soc: qcom: Separate kryo l2 accessors from PMU driver clk: meson: meson8b: add the vclk2_en gate clock clk: meson: meson8b: add the vclk_en gate clock clk: qcom: Fix return value check in apss_ipq6018_probe() clk: bcm: dvp: Add missing module informations clk: meson: meson8b: Drop CLK_IS_CRITICAL from fclk_div2 ...
