1Device tree bindings for HiSilicon INNO USB2 PHY 2 3Required properties: 4- compatible: Should be one of the following strings: 5 "hisilicon,inno-usb2-phy", 6 "hisilicon,hi3798cv200-usb2-phy". 7- reg: Should be the address space for PHY configuration register in peripheral 8 controller, e.g. PERI_USB0 for USB 2.0 PHY01 on Hi3798CV200 SoC. 9- clocks: The phandle and clock specifier pair for INNO USB2 PHY device 10 reference clock. 11- resets: The phandle and reset specifier pair for INNO USB2 PHY device reset 12 signal. 13- #address-cells: Must be 1. 14- #size-cells: Must be 0. 15 16The INNO USB2 PHY device should be a child node of peripheral controller that 17contains the PHY configuration register, and each device supports up to 2 PHY 18ports which are represented as child nodes of INNO USB2 PHY device. 19 20Required properties for PHY port node: 21- reg: The PHY port instance number. 22- #phy-cells: Defined by generic PHY bindings. Must be 0. 23- resets: The phandle and reset specifier pair for PHY port reset signal. 24 25Refer to phy/phy-bindings.txt for the generic PHY binding properties 26 27Example: 28 29perictrl: peripheral-controller@8a20000 { 30 compatible = "hisilicon,hi3798cv200-perictrl", "simple-mfd"; 31 reg = <0x8a20000 0x1000>; 32 #address-cells = <1>; 33 #size-cells = <1>; 34 ranges = <0x0 0x8a20000 0x1000>; 35 36 usb2_phy1: usb2-phy@120 { 37 compatible = "hisilicon,hi3798cv200-usb2-phy"; 38 reg = <0x120 0x4>; 39 clocks = <&crg HISTB_USB2_PHY1_REF_CLK>; 40 resets = <&crg 0xbc 4>; 41 #address-cells = <1>; 42 #size-cells = <0>; 43 44 usb2_phy1_port0: phy@0 { 45 reg = <0>; 46 #phy-cells = <0>; 47 resets = <&crg 0xbc 8>; 48 }; 49 50 usb2_phy1_port1: phy@1 { 51 reg = <1>; 52 #phy-cells = <0>; 53 resets = <&crg 0xbc 9>; 54 }; 55 }; 56 57 usb2_phy2: usb2-phy@124 { 58 compatible = "hisilicon,hi3798cv200-usb2-phy"; 59 reg = <0x124 0x4>; 60 clocks = <&crg HISTB_USB2_PHY2_REF_CLK>; 61 resets = <&crg 0xbc 6>; 62 #address-cells = <1>; 63 #size-cells = <0>; 64 65 usb2_phy2_port0: phy@0 { 66 reg = <0>; 67 #phy-cells = <0>; 68 resets = <&crg 0xbc 10>; 69 }; 70 }; 71}; 72
