Linus Torvalds f4a6365ae8 There are a few changes to the core framework this time around, in addition to
the normal collection of driver updates to support new SoCs, fix incorrect
 data, and convert various drivers to clk_hw based APIs.
 
 In the core, we allow clk_ops::init() to return an error code now so that we
 can fail clk registration if the callback does something like fail to allocate
 memory. We also add a new "terminate" clk_op so that things done in
 clk_ops::init() can be undone, e.g. free memory. We also spit out a warning now
 when critical clks fail to enable and we support changing clk rates and
 enable/disable state through debugfs when developers compile the kernel
 themselves.
 
 On the driver front, we get support for what seems like a lot of Qualcomm and
 NXP SoCs given that those vendors dominate the diffstat. There are a couple new
 drivers for Xilinx and Amlogic SoCs too. The updates are all small things like
 fixing the way glitch free muxes switch parents, avoiding div-by-zero problems,
 or fixing data like parent names. See the updates section below for more
 details.
 
 Finally, the "basic" clk types have been converted to support specifying
 parents with clk_hw pointers. This work includes an overhaul of the fixed-rate
 clk type to be more modern by using clk_hw APIs.
 
 Core:
  - Let clk_ops::init() return an error code
  - Add a clk_ops::terminate() callback to undo clk_ops::init()
  - Warn about critical clks that fail to enable or prepare
  - Support dangerous debugfs actions on clks with dead code
 
 New Drivers:
  - Support for Xilinx Versal platform clks
  - Display clk controller on qcom sc7180
  - Video clk controller on qcom sc7180
  - Graphics clk controller on qcom sc7180
  - CPU PLLs for qcom msm8916
  - Move qcom msm8974 gfx3d clk to RPM control

  - Add Amlogic meson8b DDR clock controller
  - Add input clocks to Amlogic meson8b controllers
  - Add SPIBSC (SPI FLASH) clock on Renesas RZ/A2
  - i.MX8MP clk driver support
 
 Updates:
  - Convert gpio, fixed-factor, mux, gate, divider basic clks to hw based APIs
  - Detect more PRMCU variants in ux500 driver
  - Adjust the composite clk type to new way of describing clk parents
  - Fixes for clk controllers on qcom msm8998 SoCs

    pll4_post_div on imx6q
  - Fix watchdog2 clock name typo in imx7ulp clock driver
  - Set CLK_GET_RATE_NOCACHE flag for DRAM related clocks on i.MX8M SoCs
  - Suppress bind attrs for i.MX8M clock driver

    devm_platform_ioremap_resource() shouldn't be used for the driver
