- Renesas Electronics USBHS driver
- Required properties:
- - compatible: Must contain one or more 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-r8a7792" for r8a7792 (R-Car V2H) compatible device
- - "renesas,usbhs-r8a7793" for r8a7793 (R-Car M2-N) compatible device
- - "renesas,usbhs-r8a7794" for r8a7794 (R-Car E2) compatible device
- - "renesas,usbhs-r8a7795" for r8a7795 (R-Car H3) compatible device
- - "renesas,usbhs-r8a7796" for r8a7796 (R-Car M3-W) compatible device
- - "renesas,rcar-gen2-usbhs" for R-Car Gen2 compatible device
- - "renesas,rcar-gen3-usbhs" for R-Car Gen3 compatible device
- When compatible with the generic version, nodes must list the
- SoC-specific version corresponding to the platform first followed
- by the generic version.
- - 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", "renesas,rcar-gen2-usbhs";
- reg = <0 0xe6590000 0 0x100>;
- interrupts = <0 107 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&mstp7_clks R8A7790_CLK_HSUSB>;
- };
