Pull clk updates from Stephen Boyd:
 "We have a small collection of core framework updates this time, mostly
  around clk registration by clk providers and debugfs "nice to haves"
  for rate constraints. I'll highlight that we're now setting the
  clk_init_data pointer inside struct clk_hw to NULL during
  clk_register(), which may break some drivers that thought they could
  use that pointer during normal operations. That change has been
  sitting in next for a while now but maybe something is still broken.
  We'l see. Other than that the core framework changes aren't invasive
  and they're fixing bugs, simplifying, and making things better.

  On the clk driver side we got the usual addition of new SoC support,
  new features for existing drivers, and bug fixes scattered throughout.
  The biggest diffstat is the Amlogic driver that gained CPU clk support
  in addition to migrating to the new way of specifying clk parents.
  After that the Qualcomm, i.MX, Mediatek, and Rockchip clk drivers got
  support for various new SoCs and clock controllers from those vendors.

  Core:
   - Drop NULL checks in clk debugfs
   - Add min/max rates to clk debugfs
   - Set clk_init_data pointer inside clk_hw to NULL after registration
   - Make clk_bulk_get_all() return an 'id' corresponding to clock-names
   - Evict parents from parent cache when they're unregistered

  New Drivers:
   - Add clock driver for i.MX8MN SoCs
   - Support aspeed AST2600 SoCs
   - Support for Mediatek MT6779 SoCs
   - Support qcom SM8150 GCC and RPMh clks
   - Support qcom QCS404 WCSS clks
   - Add CPU clock support for Armada 7K/8K (specifically AP806 and AP807)
   - Addition of clock driver for Rockchip rk3308 SoCs

  Updates:
   - Add regulator support to the cdce925 clk driver
   - Add support for Raspberry Pi 4 bcm2711 SoCs
   - Add SDIO gate support to aspeed driver
   - Add missing of_node_put() calls in various clk drivers
   - Migrate Amlogic driver to new clock parent description method
   - Add DVFS support to Amlogic Meson g12
   - Add Amlogic Meson g12a reset support to the axg audio clock controller
   - Add sm1 support to the Amlogic Meson g12a clock controller
   - Switch i.MX8MM clock driver to platform driver
   - Add Hifi4 DSP related clocks for i.MX8QXP SoC
   - Fix Audio PLL setting and parent clock for USB
   - Misc i.MX8 clock driver improvements and corrections
   - Set floor ops for Qualcomm SD clks so that rounding works
   - Fix "always-on" Clock Domains on Renesas R-Car M1A, RZ/A1, RZ/A2, and RZ/N1
   - Enable the Allwinner V3 SoC and fix the i2s clock for H6"
