1*c66ec88fSEmmanuel VadotDriver for Broadcom Northstar USB 2.0 PHY 2*c66ec88fSEmmanuel Vadot 3*c66ec88fSEmmanuel VadotRequired properties: 4*c66ec88fSEmmanuel Vadot- compatible: brcm,ns-usb2-phy 5*c66ec88fSEmmanuel Vadot- reg: iomem address range of DMU (Device Management Unit) 6*c66ec88fSEmmanuel Vadot- reg-names: "dmu", the only needed & supported reg right now 7*c66ec88fSEmmanuel Vadot- clocks: USB PHY reference clock 8*c66ec88fSEmmanuel Vadot- clock-names: "phy-ref-clk", the only needed & supported clock right now 9*c66ec88fSEmmanuel Vadot 10*c66ec88fSEmmanuel VadotTo initialize USB 2.0 PHY driver needs to setup PLL correctly. To do this it 11*c66ec88fSEmmanuel Vadotrequires passing phandle to the USB PHY reference clock. 12*c66ec88fSEmmanuel Vadot 13*c66ec88fSEmmanuel VadotExample: 14*c66ec88fSEmmanuel Vadot usb2-phy { 15*c66ec88fSEmmanuel Vadot compatible = "brcm,ns-usb2-phy"; 16*c66ec88fSEmmanuel Vadot reg = <0x1800c000 0x1000>; 17*c66ec88fSEmmanuel Vadot reg-names = "dmu"; 18*c66ec88fSEmmanuel Vadot #phy-cells = <0>; 19*c66ec88fSEmmanuel Vadot clocks = <&genpll BCM_NSP_GENPLL_USB_PHY_REF_CLK>; 20*c66ec88fSEmmanuel Vadot clock-names = "phy-ref-clk"; 21*c66ec88fSEmmanuel Vadot }; 22
