1Allwinner Display Engine 2.0/3.0 Clock Control Binding
2------------------------------------------------------
3
4Required properties :
5- compatible: must contain one of the following compatibles:
6 - "allwinner,sun8i-a83t-de2-clk"
7 - "allwinner,sun8i-h3-de2-clk"
8 - "allwinner,sun8i-v3s-de2-clk"
9 - "allwinner,sun50i-a64-de2-clk"
10 - "allwinner,sun50i-h5-de2-clk"
11 - "allwinner,sun50i-h6-de3-clk"
12
13- reg: Must contain the registers base address and length
14- clocks: phandle to the clocks feeding the display engine subsystem.
15 Three are needed:
16 - "mod": the display engine module clock (on A83T it's the DE PLL)
17 - "bus": the bus clock for the whole display engine subsystem
18- clock-names: Must contain the clock names described just above
19- resets: phandle to the reset control for the display engine subsystem.
20- #clock-cells : must contain 1
21- #reset-cells : must contain 1
22
23Example:
24de2_clocks: clock@1000000 {
25 compatible = "allwinner,sun8i-h3-de2-clk";
26 reg = <0x01000000 0x100000>;
27 clocks = <&ccu CLK_BUS_DE>,
28 <&ccu CLK_DE>;
29 clock-names = "bus",
30 "mod";
31 resets = <&ccu RST_BUS_DE>;
32 #clock-cells = <1>;
33 #reset-cells = <1>;
34};
