    Pull clk subsystem updates from Stephen Boyd:
     "We have a fairly balanced mix of clk driver updates and clk framework
      updates this time around. It's the usual pile of new drivers for new
      hardware out there and the normal small fixes and updates, but then we
      have some core framework changes too.
    
      In the core framework, we introduce support for a clk_get_optional()
      API to get clks that may not always be populated and a way to devm
      manage clkdev lookups registered by provider drivers. We also do some
      refactoring to simplify the interface between clkdev and the common
      clk framework so we can reuse the DT parsing and clk_get() path in
      provider drivers in the future. This work will continue in the next
      few cycles while we convert how providers specify clk parents.
    
      On the driver side, the biggest part of the dirstat is the Amlogic clk
      driver that got support for the G12A SoC. It dominates with almost
      half the overall diff, while the second largest part of the diff is in
      the i.MX clk driver that gained support for imx8mm SoCs. After that,
      we have the Actions Semiconductor and Qualcomm drivers rounding out
      the big part of the dirstat because they both got new hardware support
      for SoCs. The rest is just various updates and non-critical fixes for
      existing drivers.
    
      Core:
       - Convert a few clk bindings to JSON schema format
       - Add a {devm_}clk_get_optional() API
       - Add devm_clk_hw_register_clkdev() API to manage clkdev lookups
       - Start rewriting clk parent registration and supporting device links
         by moving around code that supports clk_get() and DT parsing of the
         'clocks' property
    
      New Drivers:
       - Add Qualcomm MSM8998 RPM managed clks
       - IPA clk support on Qualcomm RPMh clk controllers
       - Actions Semi S500 SoC clk support
       - Support for fixed rate clks populated from an MMIO register
       - Add RPC (QSPI/HyperFLASH) clocks on Renesas R-Car V3H
       - Add TMU (timer) clocks on Renesas RZ/G2E
       - Add Amlogic G12A Always-On Clock Controller
       - Add 32k clock generation for Amlogic AXG
       - Add support for the Mali GPU clocks on Amlogic Meson8
       - Add Amlogic G12A EE clock controller driver
       - Add missing CANFD clocks on Renesas RZ/G2M and RZ/G2E
       - Add i.MX8MM SoC clk driver support
    
      Removed Drivers:
       - Remove clps711x driver as the board support is gone
    
      Updates:
       - 3rd ECO fix for Mediatek MT2712 SoCs
       - Updates for Qualcomm MSM8998 GCC clks
       - Random static analysis fixes for clk drivers
       - Support for sleeping gpios in the clk-gpio type
       - Minor fixes for STM32MP1 clk driver (parents, critical flag, etc.)
       - Split LCDC into two clks on the Marvell MMP2 SoC
       - Various DT of_node refcount fixes
       - Get rid of CLK_IS_BASIC from TI code (yay!)
       - TI Autoidle clk support
       - Fix Amlogic Meson8 APB clock ID name
       - Claim input clocks through DT for Amlogic AXG and GXBB
       - Correct the DU (display unit) parent clock on Renesas RZ/G2E
       - Exynos5433 IMEM CMU crypto clk support (SlimSS)
       - Fix for the PLL-MIPI on the Allwinner A23
       - Fix Rockchip rk3328 PLL rate calculation
       - Add SET_RATE_PARENT flag on display clk of Rockhip rk3066
       - i.MX SCU clk driver clk_set_parent() and cpufreq support"
