- compatible: Must contain one of the following:
- "renesas,usbhs-r8a7790"
- "renesas,usbhs-r8a7791"
- reg: Base address and length of the register for the USBHS
- interrupts: Interrupt specifier for the USBHS
- clocks: A list of phandle + clock specifier pairs
Optional properties:
- renesas,buswait: Integer to use BUSWAIT register
- renesas,enable-gpio: A gpio specifier to check GPIO determining if USB
function should be enabled
- phys: phandle + phy specifier pair
- phy-names: must be "usb"
- dmas: Must contain a list of references to DMA specifiers.
- dma-names : Must contain a list of DMA names:
- tx0 ... tx<n>
- rx0 ... rx<n>
- This <n> means DnFIFO in USBHS module.
Example:
usbhs: usb@e6590000 {
compatible = "renesas,usbhs-r8a7790";
reg = <0 0xe6590000 0 0x100>;
interrupts = <0 107 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&mstp7_clks R8A7790_CLK_HSUSB>;
};
