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>;
};
