1ROCKCHIP USB2.0 PHY WITH INNO IP BLOCK 2 3Required properties (phy (parent) node): 4 - compatible : should be one of the listed compatibles: 5 * "rockchip,rk3228-usb2phy" 6 * "rockchip,rk3328-usb2phy" 7 * "rockchip,rk3366-usb2phy" 8 * "rockchip,rk3399-usb2phy" 9 * "rockchip,rv1108-usb2phy" 10 - reg : the address offset of grf for usb-phy configuration. 11 - #clock-cells : should be 0. 12 - clock-output-names : specify the 480m output clock name. 13 14Optional properties: 15 - clocks : phandle + phy specifier pair, for the input clock of phy. 16 - clock-names : input clock name of phy, must be "phyclk". 17 - assigned-clocks : phandle of usb 480m clock. 18 - assigned-clock-parents : parent of usb 480m clock, select between 19 usb-phy output 480m and xin24m. 20 Refer to clk/clock-bindings.txt for generic clock 21 consumer properties. 22 - rockchip,usbgrf : phandle to the syscon managing the "usb general 23 register files". When set driver will request its 24 phandle as one companion-grf for some special SoCs 25 (e.g RV1108). 26 27Required nodes : a sub-node is required for each port the phy provides. 28 The sub-node name is used to identify host or otg port, 29 and shall be the following entries: 30 * "otg-port" : the name of otg port. 31 * "host-port" : the name of host port. 32 33Required properties (port (child) node): 34 - #phy-cells : must be 0. See ./phy-bindings.txt for details. 35 - interrupts : specify an interrupt for each entry in interrupt-names. 36 - interrupt-names : a list which should be one of the following cases: 37 Regular case: 38 * "otg-id" : for the otg id interrupt. 39 * "otg-bvalid" : for the otg vbus interrupt. 40 * "linestate" : for the host/otg linestate interrupt. 41 Some SoCs use one interrupt with the above muxed together, so for these 42 * "otg-mux" : otg-port interrupt, which mux otg-id/otg-bvalid/linestate 43 to one. 44 45Optional properties: 46 - phy-supply : phandle to a regulator that provides power to VBUS. 47 See ./phy-bindings.txt for details. 48 49Example: 50 51grf: syscon@ff770000 { 52 compatible = "rockchip,rk3366-grf", "syscon", "simple-mfd"; 53 #address-cells = <1>; 54 #size-cells = <1>; 55 56... 57 58 u2phy: usb2-phy@700 { 59 compatible = "rockchip,rk3366-usb2phy"; 60 reg = <0x700 0x2c>; 61 #clock-cells = <0>; 62 clock-output-names = "sclk_otgphy0_480m"; 63 64 u2phy_otg: otg-port { 65 #phy-cells = <0>; 66 interrupts = <GIC_SPI 93 IRQ_TYPE_LEVEL_HIGH>, 67 <GIC_SPI 94 IRQ_TYPE_LEVEL_HIGH>, 68 <GIC_SPI 95 IRQ_TYPE_LEVEL_HIGH>; 69 interrupt-names = "otg-id", "otg-bvalid", "linestate"; 70 }; 71 72 u2phy_host: host-port { 73 #phy-cells = <0>; 74 interrupts = <GIC_SPI 96 IRQ_TYPE_LEVEL_HIGH>; 75 interrupt-names = "linestate"; 76 }; 77 }; 78}; 79
