65 The first phandle argument in the PHY specifier identifies the PHY, its
66 meaning is compatible dependent. For the currently supported SoCs (Exynos 4210
67 and Exynos 4212) it is as follows:
68 0 - USB device ("device"),
69 1 - USB host ("host"),
72 Exynos3250 has only USB device phy available as phy 0.
74 Exynos 4210 and Exynos 4212 use mode switching and require that mode switch
79 For Exynos 4412 (compatible with Exynos 4212):
81 usbphy: phy@125b0000 {
82 compatible = "samsung,exynos4x12-usb2-phy";
83 reg = <0x125b0000 0x100>;
84 clocks = <&clock 305>, <&clock 2>;
85 clock-names = "phy", "ref";
87 samsung,sysreg-phandle = <&sys_reg>;
88 samsung,pmureg-phandle = <&pmu_reg>;
91 Then the PHY can be used in other nodes such as:
93 phy-consumer@12340000 {
98 Refer to DT bindings documentation of particular PHY consumer devices for more
99 information about required PHYs and the way of specification.

181 samsung,pmu-syscon = <&pmu_system_controller>;
185 - aliases: For SoCs like Exynos5420 having multiple USB 3.0 DRD PHY controllers,
186 'usbdrd_phy' nodes should have numbered alias in the aliases node,
187 in the form of usbdrdphyN, N = 0, 1... (depending on number of
