1Driver for Broadcom Northstar USB 2.0 PHY 2 3Required properties: 4- compatible: brcm,ns-usb2-phy 5- reg: iomem address range of DMU (Device Management Unit) 6- reg-names: "dmu", the only needed & supported reg right now 7- clocks: USB PHY reference clock 8- clock-names: "phy-ref-clk", the only needed & supported clock right now 9 10To initialize USB 2.0 PHY driver needs to setup PLL correctly. To do this it 11requires passing phandle to the USB PHY reference clock. 12 13Example: 14 usb2-phy { 15 compatible = "brcm,ns-usb2-phy"; 16 reg = <0x1800c000 0x1000>; 17 reg-names = "dmu"; 18 #phy-cells = <0>; 19 clocks = <&genpll BCM_NSP_GENPLL_USB_PHY_REF_CLK>; 20 clock-names = "phy-ref-clk"; 21 }; 22
