|
- "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,usbhs-r8a77965" for r8a77965 (R-Car M3-N) compatible device
|
- "renesas,usbhs-r8a77995" for r8a77995 (R-Car D3) compatible device
|
- "renesas,usbhs-r7s72100" for r7s72100 (RZ/A1) compatible device
|
- "renesas,rcar-gen2-usbhs" for R-Car Gen2 or RZ/G1 compatible devices
|
- "renesas,rcar-gen3-usbhs" for R-Car Gen3 compatible device
|
- "renesas,rza1-usbhs" for RZ/A1 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>;
|
};
