Renesas Electronics USBHS driver
Required properties:
usb: renesas_usbhs: add fallback compatibility strings Add fallback compatibility strings for R-Car Gen2 and Gen3. This is in keeping with the fallback scheme being adopted wherever appropriate for drivers for Renesas SoCs.

- compatible: Must contain one or more of the following:
usb: renesas_usbhs: Add compatible string for r8a7743/5 This patch adds support for r8a7743/5 SoCs. The Renesas RZ/G1[ME] (R8A7743/5) usbhs is identical to the R-Car Gen2 family. No driver change is needed due to the fallback compatible value "renesas,rcar-gen2-usbhs". Adding the SoC-specific compatible values here has two purposes: 1. Document which SoCs have this hardware module, 2. Allow checkpatch to validate compatible values.

usb: renesas_usbhs: add support for R-Car D3 This patch adds support for R-Car D3. This SoC needs to release the PLL reset by the UGCTRL register. So, since this is not the same as other R-Car Gen3 SoCs, this patch adds a new type as "USBHS_TYPE_RCAR_GEN3_WITH_PLL".

- dmas: Must contain a list of references to DMA specifiers.
usb: renesas_usbhs: Revise the binding document about the dma-names Since the DT should describe the hardware (not the driver limitation), This patch revises the binding document about the dma-names to change simple numbering as "ch%d" instead of "tx<n>" and "rx<n>". Also this patch fixes the actual code of renesas_usbhs driver to handle the new dma-names.
