Kernel-4.18.0-80.el8_sun8i-de2

Allwinner Display Engine 2.0 Clock Control Binding

Required properties :

  • compatible: must contain one of the following compatibles:

      - "allwinner,sun8i-a83t-de2-clk"
      - "allwinner,sun8i-h3-de2-clk"
      - "allwinner,sun8i-v3s-de2-clk"
      - "allwinner,sun50i-h5-de2-clk"
    
  • 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 (on A83T it’s the DE PLL)
    • “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:
de2_clocks: clock@1000000 {
compatible = “allwinner,sun8i-h3-de2-clk”;
reg = <0x01000000 0x100000>;
clocks = <&ccu CLK_BUS_DE>,
<&ccu CLK_DE>;
clock-names = “bus”,
“mod”;
resets = <&ccu RST_BUS_DE>;
#clock-cells = <1>;
#reset-cells = <1>;
};
