Renesas Electronics USBHS driver
Required properties:
- compatible: Must contain one of the following:
- "renesas,usbhs-r8a7790" for r8a7790 (R-Car H2) compatible device
- "renesas,usbhs-r8a7791" for r8a7791 (R-Car M2-W) compatible device
- "renesas,usbhs-r8a7794" for r8a7794 (R-Car E2) compatible device
- "renesas,usbhs-r8a7795" for r8a7795 (R-Car H3) compatible device
- 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 : named "ch%d", where %d is the channel number ranging from zero
to the number of channels (DnFIFOs) minus one.
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>;
};
