Platform DesignWare HS OTG USB 2.0 controller
-----------------------------------------------------
Required properties:
- compatible : One of:
- brcm,bcm2835-usb: The DWC2 USB controller instance in the BCM2835 SoC.
- rockchip,rk3066-usb: The DWC2 USB controller instance in the rk3066 Soc;
- "rockchip,rk3188-usb", "rockchip,rk3066-usb", "snps,dwc2": for rk3188 Soc;
- "rockchip,rk3288-usb", "rockchip,rk3066-usb", "snps,dwc2": for rk3288 Soc;
- snps,dwc2: A generic DWC2 USB controller with default parameters.
- reg : Should contain 1 register range (address and length)
- interrupts : Should contain 1 interrupt
- clocks: clock provider specifier
- clock-names: shall be "otg"
Refer to clk/clock-bindings.txt for generic clock consumer properties
Optional properties:
- phys: phy provider specifier
- phy-names: shall be "usb2-phy"
Refer to phy/phy-bindings.txt for generic phy consumer properties
- dr_mode: shall be one of "host", "peripheral" and "otg"
Refer to usb/generic.txt
- g-use-dma: enable dma usage in gadget driver.
- g-rx-fifo-size: size of rx fifo size in gadget mode.
- g-np-tx-fifo-size: size of non-periodic tx fifo size in gadget mode.
- g-tx-fifo-size: size of periodic tx fifo per endpoint (except ep0) in gadget mode.
Example:
usb@101c0000 {
compatible = "ralink,rt3050-usb, snps,dwc2";
reg = <0x101c0000 40000>;
interrupts = <18>;
clocks = <&usb_otg_ahb_clk>;
clock-names = "otg";
phys = <&usbphy>;
phy-names = "usb2-phy";
};
