Renesas Electronics USBHS driver Required properties: - 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 - rx0 ... rx - This 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>; };
