I reworked the reg-names and clock-names to be more concise and applied. 
Like this:

  clock-names:
    description:
      Target module clock names like "fck", "ick", "optck1", "optck2"
      if the clocks are configurable.
    oneOf:
      - enum: [ ick, fck, sys_clk ]
      - items:
          - const: fck
          - enum: [ ick. dbclk, osc, sys_clk, dss_clk, ahclkx ]
      - items:
          - const: fck
          - const: phy-clk
          - const: phy-clk-div
      - items:
          - const: fck
          - const: hdmi_clk
          - const: sys_clk
          - const: tv_clk
      - items:
          - const: fck
          - const: ahclkx
          - const: ahclkr
