Allwinner A80 Display Engine Clock Control Binding

Required properties :

  • compatible: must contain one of the following compatibles:

      - "allwinner,sun9i-a80-de-clks"
    
  • reg: Must contain the registers base address and length

  • clocks: phandle to the clocks feeding the display engine subsystem.

    Three are needed:
    
    • “mod”: the display engine module clock
    • “dram”: the DRAM bus clock for the system
    • “bus”: the bus clock for the whole display engine subsystem
  • clock-names: Must contain the clock names described just above

  • resets: phandle to the reset control for the display engine subsystem.

  • #clock-cells : must contain 1

  • #reset-cells : must contain 1

Example:
de_clocks: clock@3000000 {
compatible = “allwinner,sun9i-a80-de-clks”;
reg = <0x03000000 0x30>;
clocks = <&ccu CLK_DE>, <&ccu CLK_SDRAM>, <&ccu CLK_BUS_DE>;
clock-names = “mod”, “dram”, “bus”;
resets = <&ccu RST_BUS_DE>;
#clock-cells = <1>;
#reset-cells = <1>;
};
