Allwinner A80 USB Clock Control Binding
|
|
---------------------------------------
|
|
|
|
Required properties :
|
|
- compatible: must contain one of the following compatibles:
|
|
- "allwinner,sun9i-a80-usb-clocks"
|
|
|
|
- reg: Must contain the registers base address and length
|
|
- clocks: phandle to the clocks feeding the USB subsystem. Two are needed:
|
|
- "bus": the bus clock for the whole USB subsystem
|
|
- "hosc": the high frequency oscillator (usually at 24MHz)
|
|
- clock-names: Must contain the clock names described just above
|
|
- #clock-cells : must contain 1
|
|
- #reset-cells : must contain 1
|
|
|
|
Example:
|
|
usb_clocks: clock@a08000 {
|
|
compatible = "allwinner,sun9i-a80-usb-clks";
|
|
reg = <0x00a08000 0x8>;
|
|
clocks = <&ccu CLK_BUS_USB>, <&osc24M>;
|
|
clock-names = "bus", "hosc";
|
|
#clock-cells = <1>;
|
|
#reset-cells = <1>;
|
|
};
