1Allwinner Display Engine 2.0 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-h5-de2-clk"
10
11- reg: Must contain the registers base address and length
12- clocks: phandle to the clocks feeding the display engine subsystem.
13 Three are needed:
14 - "mod": the display engine module clock (on A83T it's the DE PLL)
15 - "bus": the bus clock for the whole display engine subsystem
16- clock-names: Must contain the clock names described just above
17- resets: phandle to the reset control for the display engine subsystem.
18- #clock-cells : must contain 1
19- #reset-cells : must contain 1

21Example:
22de2_clocks: clock@1000000 {
23 compatible = "allwinner,sun8i-h3-de2-clk";
24 reg = <0x01000000 0x100000>;
25 clocks = <&ccu CLK_BUS_DE>,
26 <&ccu CLK_DE>;
27 clock-names = "bus",
28 "mod";
29 resets = <&ccu RST_BUS_DE>;
30 #clock-cells = <1>;
31 #reset-cells = <1>;
32};
