Pull clk updates from Stephen Boyd:
 "This round is dominated by NXP's i.MX clk drivers. We gained support
  for two or three i.MX SoCs in here and that mostly means a lot of
  driver code and data.

  Beyond that platform, there are some new Mediatek, Amlogic, and
  Qualcomm clk drivers added in here, and then we get to the long tail
  of driver updates and non-critical fixes all around, including code
  for vendors such as Renesas, Rockchip, Nvidia, and Allwinner. Overall,
  the driver updates look normal.

  Apart from the usual driver updates we have an update to make
  registering OF based clk providers a little simpler when they're
  devices created as a child of a device backed by a node in DT. Drivers
  don't have to jump through hoops to unregister the provider upon
  driver removal anymore because the API does the right thing and uses
  the parent device DT node.

  Summary:

  Core:
   - Make devm_of_clk_add_hw_provider() use parent dt node if necessary
   - Various SPDX taggings
   - Mark clk_ops const when possible

  New Drivers:
   - NXP i.MX7ULP SoC clock support
   - NXP i.MX8QXP SoC clock support
   - NXP i.MX8MQ SoC clock support
   - NXP QorIQ T1023 SoC support
   - Qualcomm SDM845 audio subsystem clks
   - Qualcomm SDM845 GPU clck controllers
   - Qualcomm QCS404 RPM clk support
   - Mediatek MT7629 SoC clk controllers
   - Allwinner F1c100s SoC clocks
   - Allwinner H6 display engine clocks
   - Amlogic GX video clocks
   - Support for Amlogic meson8b CPU frequency scaling
   - Amlogic Meson8b CPU post-divider clocks

  Updates:
   - Proper suspend/resume on VersaClock5
   - Shrink code some with DEFINE_SHOW_ATTRIBUTE()
   - Register fixes for Rockchip rk3188 and rk3328
   - One new critical clock for Rockchip rk3188 and a fixed clock id
     (double used number)
   - New clock id for Rockchip rk3328
   - Amlogic Meson8/Meson8b video clock support
   - Amlogic got a clk-input helper and used it for the axg-audio clock
     driver
   - Sigma Delta modulation for the Allwinner A33 audio clocks
   - Support for CPEX (timer) clocks on various Renesas R-Car Gen3 and
     RZ/G2 SoCs
   - Support for SDHI HS400 clocks on early revisions of Renesas R-Car
     H3 and M3-W
   - Support for SDHI and USB clocks on Renesas RZ/A2
   - Support for RPC (SPI Multi I/O Bus Controller) clocks on Renesas
     R-Car V3M
   - Qualcomm MSM8998 GCC driver improvements (resets, drop unused clks,
     etc)"
