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>;
|
|
};
