ROCKCHIP USB2 PHY
Required properties:
- compatible: matching the soc type, one of
"rockchip,rk3066a-usb-phy"
"rockchip,rk3188-usb-phy"
"rockchip,rk3288-usb-phy"
- #address-cells: should be 1
- #size-cells: should be 0
Deprecated properties:
- rockchip,grf : phandle to the syscon managing the "general
register files" - phy should be a child of the GRF instead
Sub-nodes:
Each PHY should be represented as a sub-node.
Sub-nodes
required properties:
- #phy-cells: should be 0
- reg: PHY configure reg address offset in GRF
"0x320" - for PHY attach to OTG controller
"0x334" - for PHY attach to HOST0 controller
"0x348" - for PHY attach to HOST1 controller
Optional Properties:
- clocks : phandle + clock specifier for the phy clocks
- clock-names: string, clock name, must be "phyclk"
- #clock-cells: for users of the phy-pll, should be 0
- reset-names: Only allow the following entries:
- phy-reset
- resets: Must contain an entry for each entry in reset-names.
Example:
grf: syscon@ff770000 {
compatible = "rockchip,rk3288-grf", "syscon", "simple-mfd";
...
usbphy: phy {
compatible = "rockchip,rk3288-usb-phy";
#address-cells = <1>;
#size-cells = <0>;
usbphy0: usb-phy0 {
#phy-cells = <0>;
reg = <0x320>;
};
};
};
