1 Samsung Exynos SoC USB controller
3 The USB devices interface with USB controllers on Exynos SOCs.
4 The device node has following properties.
8 - compatible: should be "samsung,exynos4210-ehci" for USB 2.0
9 EHCI controller in host mode.
10 - reg: physical base address of the controller and length of memory mapped
12 - interrupts: interrupt number to the cpu.
13 - clocks: from common clock binding: handle to usb clock.
14 - clock-names: from common clock binding: Shall be "usbhost".
15 - phys: from the *Generic PHY* bindings; array specifying phy(s) used
17 - phy-names: from the *Generic PHY* bindings; array of the names for
18 each phy for the root ports, must be a subset of the following:
19 "host", "hsic0", "hsic1".
22 - samsung,vbus-gpio: if present, specifies the GPIO that
23 needs to be pulled up for the bus to be powered.
28 compatible = "samsung,exynos4210-ehci";
29 reg = <0x12110000 0x100>;
30 interrupts = <0 71 0>;
31 samsung,vbus-gpio = <&gpx2 6 1 3 3>;
33 clocks = <&clock 285>;
34 clock-names = "usbhost";
42 - compatible: should be "samsung,exynos4210-ohci" for USB 2.0
43 OHCI companion controller in host mode.
44 - reg: physical base address of the controller and length of memory mapped
46 - interrupts: interrupt number to the cpu.
47 - clocks: from common clock binding: handle to usb clock.
48 - clock-names: from common clock binding: Shall be "usbhost".
49 - phys: from the *Generic PHY* bindings; array specifying phy(s) used
51 - phy-names: from the *Generic PHY* bindings; array of the names for
52 each phy for the root ports, must be a subset of the following:
53 "host", "hsic0", "hsic1".
57 compatible = "samsung,exynos4210-ohci";
58 reg = <0x12120000 0x100>;
59 interrupts = <0 71 0>;
61 clocks = <&clock 285>;
62 clock-names = "usbhost";
70 - compatible: should be one of the following -
71 "samsung,exynos5250-dwusb3": for USB 3.0 DWC3 controller on
73 "samsung,exynos5433-dwusb3": for USB 3.0 DWC3 controller on
75 "samsung,exynos7-dwusb3": for USB 3.0 DWC3 controller on Exynos7.
76 - #address-cells, #size-cells : should be '1' if the device has sub-nodes
78 - ranges: allows valid 1:1 translation between child's address space and
79 parent's address space
80 - clocks: Clock IDs array as required by the controller.
81 - clock-names: names of clocks correseponding to IDs in the clock property
82 - vdd10-supply: 1.0V powr supply
83 - vdd33-supply: 3.0V/3.3V power supply
86 The dwc3 core should be added as subnode to Exynos dwc3 glue.
88 The binding details of dwc3 can be found in:
