Martin Blumenstingl b78e290868 dt-bindings: phy: meson8b-usb2-phy: add support for the Meson8 SoCs
Meson8 uses the same USB PHY as found on the Meson8b and GXBB SoCs. This
adds a new compatible string to indicate that this binding also supports
the Meson8 SoCs.

* Amlogic Meson8, Meson8b and GXBB USB2 PHY
Required properties:
- compatible: Depending on the platform this should be one of:
"amlogic,meson8-usb2-phy"
"amlogic,meson8b-usb2-phy"
"amlogic,meson-gxbb-usb2-phy"
- reg: The base address and length of the registers
- #phys-cells: should be 0 (see phy-bindings.txt in this directory)
- clocks: phandle and clock identifier for the phy clocks
- clock-names: "usb_general" and "usb"
Optional properties:
- resets: reference to the reset controller
- phy-supply: see phy-bindings.txt in this directory
Example:
usb0_phy: usb-phy@c0000000 {
compatible = "amlogic,meson-gxbb-usb2-phy";
#phy-cells = <0>;
reg = <0x0 0xc0000000 0x0 0x20>;
resets = <&reset RESET_USB_OTG>;
clocks = <&clkc CLKID_USB>, <&clkc CLKID_USB0>;
clock-names = "usb_general", "usb";
phy-supply = <&usb_vbus>;
};
