    Pull clk updates from Stephen Boyd:
     "The core framework got some nice improvements this time around. We
      gained the ability to get struct clk pointers from a struct clk_hw so
      that clk providers can consume the clks they provide, if they need to
      do something like that. This has been a long missing part of the clk
      provider API that will help us move away from exposing a struct clk
      pointer in the struct clk_hw. Tracepoints are added for the
      clk_set_rate() "range" functions, similar to the tracepoints we
      already have for clk_set_rate() and we added a column to debugfs to
      help developers understand the hardware enable state of clks in case
      firmware or bootloader state is different than what is expected.
      Overall the core changes are mostly improving the clk driver writing
      experience.
    
      At the driver level, we have the usual collection of driver updates
      and new drivers for new SoCs. This time around the Qualcomm folks
      introduced a good handful of clk drivers for various parts of three or
      four SoCs. The SiFive folks added a new clk driver for their FU740
      SoCs, coming in second on the diffstat and then Atmel AT91 and Amlogic
      SoCs had lots of work done after that for various new features. One
      last thing to note in the driver area is that the i.MX driver has
      gained a new binding to support SCU clks after being on the list for
      many months. It uses a two cell binding which is sort of rare in clk
      DT bindings. Beyond that we have the usual set of driver fixes and
      tweaks that come from more testing and finding out that some
      configuration was wrong or that a driver could support being built as
      a module.
    
      Summary:
    
      Core:
       - Add some trace points for clk_set_rate() "range" functions
       - Add hardware enable information to clk_summary debugfs
       - Replace clk-provider.h with of_clk.h when possible
       - Add devm variant of clk_notifier_register()
       - Add clk_hw_get_clk() to generate a struct clk from a struct clk_hw
    
      New Drivers:
       - Bindings for Canaan K210 SoC clks
       - Support for SiFive FU740 PRCI
       - Camera clks on Qualcomm SC7180 SoCs
       - GCC and RPMh clks on Qualcomm SDX55 SoCs
       - RPMh clks on Qualcomm SM8350 SoCs
       - LPASS clks on Qualcomm SM8250 SoCs
