    Pull clk framework updates from Stephen Boyd:
     "We have a couple new features and changes in the core clk framework
      this time around because we've finally gotten around to fixing some
      long standing issues. There's still work to do though, so this pull
      request is largely laying down the foundation for all the driver
      changes to come in the next merge window.
    
      The first problem we're alleviating is how parents of clks are
      specified. With the new method, we should see lots of drivers migrate
      away from the current design of string comparisons on the entire clk
      tree to a more direct method where they can use clk_hw pointers or
      more localized names specified in DT or via clkdev. This should reduce
      our reliance on string comparisons for all the topology description
      logic that we've been using for years and hopefully speed some things
      up while avoiding problems we have with generating clk names.
    
      Beyond that we also got rid of the CLK_IS_BASIC flag because it wasn't
      really helping anyone and we introduced big-endian versions of the
      basic clk types so that we can get rid of clk_{readl,writel}(). Both
      of these are things that driver developers have tried to use over the
      years that I typically bat away during code reviews because they're
      not useful. It's great to see these two things go away so maintainers
      can save time not worrying about these things.
    
      On the driver side we got the usual collection of new SoC support and
      non-critical fixes and updates to existing code. The big topics that
      stand out are the new driver support for Mediatek MT8183 and MT8516
      SoCs, Amlogic Meson8b and G12a SoCs, and the SiFive FU540 SoC. The
      other patches in the driver pile are mostly fixes for things that are
      being used for the first time or additions for clks that couldn't be
      tested before because there wasn't a consumer driver that exercised
      them. Details are below and also in the sub-maintainer tags.
    
      Core:
       - Remove clk_readl() and introduce BE versions of basic clk types
       - Rewrite how clk parents can be specified to allow DT/clkdev lookups
       - Removal of the CLK_IS_BASIC clk flag
       - Framework documentation updates and fixes
    
      New Drivers:
       - Support for STM32F769
       - AT91 sam9x60 PMC support
       - SiFive FU540 PRCI and PLL support
       - Qualcomm QCS404 CDSP clk support
       - Qualcomm QCS404 Turing clk support
       - Mediatek MT8183 clock support
       - Mediatek MT8516 clock support
       - Milbeaut M10V clk controller support
       - Support for Cirrus Logic Lochnagar clks
    
      Updates:
       - Rework AT91 sckc DT bindings
       - Fix slow RC oscillator issue on sama5d3
       - Mark UFS clk as critical on Hi-Silicon hi3660 SoCs
       - Various static analysis fixes/finds and const markings
       - Video Engine (ECLK) support on Aspeed SoCs
       - Xilinx ZynqMP Versal platform support
       - Convert Xilinx ZynqMP driver to be struct oriented
       - Fixes for Rockchip rk3328 and rk3288 SoCs
       - Sub-type for Rockchip SoCs where mux and divider aren't a single register
       - Remove SNVS clock from i.MX7UPL clock driver and bindings
       - Improve i.MX5 clock driver for i.MX50 support
       - Addition of ADC clock definition for Exynos 5410 SoC (Odroid XU)
       - Export a new clock for the MBUS controller on the A13
       - Allwinner H6 fixes to support a finer clocking of the video and VPU engines
       - Add g12a support in the Amlogic axg audio clock controller
       - Add missing PCI USB clock on Rensas RZ/N1
       - Add Z2 (Cortex-A53) clocks on Rensas R-Car E3 and RZ/G2E
       - A new helper DIV64_U64_ROUND_CLOSEST() in <linux/math64.h>
       - VPU and Video Decoder clocks on Amlogic Meson8b
       - Finally remove the wrong ABP Meson8b clock id
       - Add Video Decoder, PCIe PLL, and CPU Clocks on Amlogic G12A
       - Re-expose SAR_ADC_SEL and CTS_OSCIN on Amlogic G12A AO clock controller
       - Un-expose some Amlogic AXG-Audio input clocks IDs"
