Stephen Boyd a1ff1ce300 Merge branches 'clk-init-destroy', 'clk-doc', 'clk-imx' and 'clk-allwinner' into clk-next 
- Set clk_init_data pointer inside clk_hw to NULL after registration

* clk-init-destroy:
  clk: Overwrite clk_hw::init with NULL during clk_register()
  clk: sunxi: Don't call clk_hw_get_name() on a hw that isn't registered
  clk: ti: Don't reference clk_init_data after registration
  clk: qcom: Remove error prints from DFS registration
  rtc: sun6i: Don't reference clk_init_data after registration
  clk: zx296718: Don't reference clk_init_data after registration
  clk: milbeaut: Don't reference clk_init_data after registration
  clk: socfpga: deindent code to proper indentation
  phy: ti: am654-serdes: Don't reference clk_init_data after registration
  clk: sprd: Don't reference clk_init_data after registration
  clk: socfpga: Don't reference clk_init_data after registration
  clk: sirf: Don't reference clk_init_data after registration
  clk: qcom: Don't reference clk_init_data after registration
  clk: meson: axg-audio: Don't reference clk_init_data after registration
  clk: lochnagar: Don't reference clk_init_data after registration
  clk: actions: Don't reference clk_init_data after registration

* clk-doc:
  clk: remove extra ---help--- tags in Kconfig
  clk: add include guard to clk-conf.h
  clk: Document of_parse_clkspec() some more
  clk: Remove extraneous 'for' word in comments

* clk-imx: (32 commits)
  clk: imx: imx8mn: fix pll mux bit
  clk: imx: imx8mm: fix pll mux bit
  clk: imx: clk-pll14xx: unbypass PLL by default
  clk: imx: pll14xx: avoid glitch when set rate
  clk: imx: imx8mn: fix audio pll setting

  ...

* clk-allwinner:
  clk: sunxi-ng: h6: Allow I2S to change parent rate
  clk: sunxi-ng: v3s: add Allwinner V3 support
  clk: sunxi-ng: v3s: add missing clock slices for MMC2 module clocks
  dt-bindings: clk: sunxi-ccu: add compatible string for V3 CCU
