1HiSilicon STB PCIE/SATA/USB3 PHY 2 3Required properties: 4- compatible: Should be "hisilicon,hi3798cv200-combphy" 5- reg: Should be the address space for COMBPHY configuration and state 6 registers in peripheral controller, e.g. PERI_COMBPHY0_CFG and 7 PERI_COMBPHY0_STATE for COMBPHY0 Hi3798CV200 SoC. 8- #phy-cells: Should be 1. The cell number is used to select the phy mode 9 as defined in <dt-bindings/phy/phy.h>. 10- clocks: The phandle to clock provider and clock specifier pair. 11- resets: The phandle to reset controller and reset specifier pair. 12 13Refer to phy/phy-bindings.txt for the generic PHY binding properties. 14 15Optional properties: 16- hisilicon,fixed-mode: If the phy device doesn't support mode select 17 but a fixed mode setting, the property should be present to specify 18 the particular mode. 19- hisilicon,mode-select-bits: If the phy device support mode select, 20 this property should be present to specify the register bits in 21 peripheral controller, as a 3 integers tuple: 22 <register_offset bit_shift bit_mask>. 23 24Notes: 25- Between hisilicon,fixed-mode and hisilicon,mode-select-bits, one and only 26 one of them should be present. 27- The device node should be a child of peripheral controller that contains 28 COMBPHY configuration/state and PERI_CTRL register used to select PHY mode. 29 Refer to arm/hisilicon/hisilicon.txt for the parent peripheral controller 30 bindings. 31 32Examples: 33 34perictrl: peripheral-controller@8a20000 { 35 compatible = "hisilicon,hi3798cv200-perictrl", "syscon", 36 "simple-mfd"; 37 reg = <0x8a20000 0x1000>; 38 #address-cells = <1>; 39 #size-cells = <1>; 40 ranges = <0x0 0x8a20000 0x1000>; 41 42 combphy0: phy@850 { 43 compatible = "hisilicon,hi3798cv200-combphy"; 44 reg = <0x850 0x8>; 45 #phy-cells = <1>; 46 clocks = <&crg HISTB_COMBPHY0_CLK>; 47 resets = <&crg 0x188 4>; 48 hisilicon,fixed-mode = <PHY_TYPE_USB3>; 49 }; 50 51 combphy1: phy@858 { 52 compatible = "hisilicon,hi3798cv200-combphy"; 53 reg = <0x858 0x8>; 54 #phy-cells = <1>; 55 clocks = <&crg HISTB_COMBPHY1_CLK>; 56 resets = <&crg 0x188 12>; 57 hisilicon,mode-select-bits = <0x0008 11 (0x3 << 11)>; 58 }; 59};
