[PATCH v10 18/18] arm64: dts: imx8mp: add PLLs to clock controller module (CCM)

[Dario Binacchi <dario.binacchi@amarulasolutions.com>]

Add the PLLs generated by anatop to the clock list of the Clock
Controller Module (CCM) node.

Changes in v10:
- Drop the v9 patches:
  16/23 dt-bindings: clock: imx8m-clock: support spread spectrum clocking
  17/23 clk: imx: pll14xx: support spread spectrum clock generation
  17/23 clk: imx8mn: support spread spectrum clock generation
  21/23 clk: imx8mp: support spread spectrum clock generation
  23/23 clk: imx8mm: support spread spectrum clock generation

Changes in v9:
- Add 'Reviewed-by' tag of Peng Fan for imx8mn platform patches
- Fix building warning raised by the kernel test robot for patch
  v8, 11/18 clk: imx: add support for i.MX8MN anatop clock driver
- Add patches for imx8m{m,p} platforms:
  - 23/23 clk: imx8mm: support spread spectrum clock generation
  - 22/23 clk: imx: add support for i.MX8MM anatop clock driver
  - 21/23 clk: imx8mp: support spread spectrum clock generation
  - 20/23 clk: imx8mp: rename ccm_base to base
  - 19/23 clk: imx: add support for i.MX8MP anatop clock driver

Changes in v8:
- Drop the patches added in version 7:
  - 10/23 dt-bindings: clock: imx8m-clock: add phandle to the anatop
  - 11/23 arm64: dts: imx8mm: add phandle to anatop within CCM
  - 12/23 arm64: dts: imx8mn: add phandle to anatop within CCM
  - 13/23 arm64: dts: imx8mp: add phandle to anatop within CCM
  - 14/23 arm64: dts: imx8mq: add phandle to anatop within CCM

Changes in v7:
- Add and manage fsl,anatop property as phandle to the anatop node with
  the new patches:
  - 10/23 dt-bindings: clock: imx8m-clock: add phandle to the anatop
  - 11/23 arm64: dts: imx8mm: add phandle to anatop within CCM
  - 12/23 arm64: dts: imx8mn: add phandle to anatop within CCM
  - 13/23 arm64: dts: imx8mp: add phandle to anatop within CCM
  - 14/23 arm64: dts: imx8mq: add phandle to anatop within CCM

Changes in v6:
- Merge patches:
  10/20 dt-bindings: clock: imx8mm: add binding definitions for anatop
  11/20 dt-bindings: clock: imx8mn: add binding definitions for anatop
  12/20 dt-bindings: clock: imx8mp: add binding definitions for anatop
  to
  05/20 dt-bindings: clock: imx8m-anatop: define clocks/clock-names
  now renamed
  05/18 dt-bindings: clock: imx8m-anatop: add oscillators and PLLs
- Split the patch
  15/20 dt-bindings-clock-imx8m-clock-support-spread-spectru.patch
  into
  12/18 dt-bindings: clock: imx8m-clock: add PLLs
  16/18 dt-bindings: clock: imx8m-clock: support spread spectrum clocking

Changes in v5:
- Fix compilation errors.
- Separate driver code from dt-bindings

Changes in v4:
- Add dt-bindings for anatop
- Add anatop driver
- Drop fsl,ssc-clocks from spread spectrum dt-bindings
- New

Changes in v3:
- Patches 1/8 has been added in version 3. The dt-bindings have
  been moved from fsl,imx8m-anatop.yaml to imx8m-clock.yaml. The
  anatop device (fsl,imx8m-anatop.yaml) is indeed more or less a
  syscon, so it represents a memory area accessible by ccm
  (imx8m-clock.yaml) to setup the PLLs.
- Patches {3,5}/8 have been added in version 3.
- Patches {4,6,8}/8 use ccm device node instead of the anatop one.

Changes in v2:
- Add "allOf:" and place it after "required:" block, like in the
  example schema.
- Move the properties definition to the top-level.
- Drop unit types as requested by the "make dt_binding_check" command.
