The cell number is used to select the phy mode as defined in <dt-bindings/phy/phy.h>. - clocks: The phandle to clock provider and clock specifier pair. - resets: The phandle to reset controller and reset specifier pair. Refer to phy/phy-bindings.txt for the generic PHY binding properties. Optional properties: - hisilicon,fixed-mode: If the phy device doesn't support mode select but a fixed mode setting, the property should be present to specify the particular mode. - hisilicon,mode-select-bits: If the phy device support mode select, this property should be present to specify the register bits in peripheral controller, as a 3 integers tuple: <register_offset bit_shift bit_mask>. Notes: - Between hisilicon,fixed-mode and hisilicon,mode-select-bits, one and only one of them should be present. - The device node should be a child of peripheral controller that contains COMBPHY configuration/state and PERI_CTRL register used to select PHY mode. Refer to arm/hisilicon/hisilicon.txt for the parent peripheral controller bindings. Examples: perictrl: peripheral-controller@8a20000 { compatible = "hisilicon,hi3798cv200-perictrl", "syscon", "simple-mfd"; reg = <0x8a20000 0x1000>; #address-cells = <1>; #size-cells = <1>; ranges = <0x0 0x8a20000 0x1000>; combphy0: phy@850 { compatible = "hisilicon,hi3798cv200-combphy"; reg = <0x850 0x8>; #phy-cells = <1>; clocks = <&crg HISTB_COMBPHY0_CLK>; resets = <&crg 0x188 4>; hisilicon,fixed-mode = <PHY_TYPE_USB3>; }; combphy1: phy@858 { compatible = "hisilicon,hi3798cv200-combphy"; reg = <0x858 0x8>; #phy-cells = <1>; clocks = <&crg HISTB_COMBPHY1_CLK>; resets = <&crg 0x188 12>; hisilicon,mode-select-bits = <0x0008 11 (0x3 << 11)>; }; }; |
