|
|
|
|
|
|
Required properties :
|
|
|
|
- compatible: must contain one of the following compatibles:
|
|
|
|
- "allwinner,sun8i-a83t-de2-clk"
|
2017-12-22 20:22:33 +08:00
|
|
|
- "allwinner,sun8i-h3-de2-clk"
|
2017-05-15 00:30:33 +08:00
|
|
|
- "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:
|
2017-12-22 20:22:33 +08:00
|
|
|
- "mod": the display engine module clock (on A83T it's the DE PLL)
|
2017-05-15 00:30:33 +08:00
|
|
|
- "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",
