| 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,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>; |
| }; |
