Driver for Broadcom Northstar USB 2.0 PHY
|
|
|
|
Required properties:
|
|
- compatible: brcm,ns-usb2-phy
|
|
- reg: iomem address range of DMU (Device Management Unit)
|
|
- reg-names: "dmu", the only needed & supported reg right now
|
|
- clocks: USB PHY reference clock
|
|
- clock-names: "phy-ref-clk", the only needed & supported clock right now
|
|
|
|
To initialize USB 2.0 PHY driver needs to setup PLL correctly. To do this it
|
|
requires passing phandle to the USB PHY reference clock.
|
|
|
|
Example:
|
|
usb2-phy {
|
|
compatible = "brcm,ns-usb2-phy";
|
|
reg = <0x1800c000 0x1000>;
|
|
reg-names = "dmu";
|
|
#phy-cells = <0>;
|
|
clocks = <&genpll BCM_NSP_GENPLL_USB_PHY_REF_CLK>;
|
|
clock-names = "phy-ref-clk";
|
|
};
