The series adds support for spread spectrum clocking for i.MX8M{N,M,P}
PLLs (audio, video and DRAM). It has been tested for the video PLL on
boards using i.MX8MN and i.MX8MP.

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.

Dario Binacchi (8):
  dt-bindings: clock: imx8m-clock: support spread spectrum clocking
  clk: imx: pll14xx: support spread spectrum clock generation
  clk: imx: imx8mm: distinguish between ccm and anatop references
  clk: imx8mm: support spread spectrum clock generation
  clk: imx: imx8mn: distinguish between ccm and anatop references
  clk: imx8mn: support spread spectrum clock generation
  clk: imx8mp: don't lose the anatop device node
  clk: imx8mp: support spread spectrum clock generation
