[PATCH v3 0/2] Add xSPI support for RZ/T2H and RZ/N2H SoCs

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>

Hi All,

Add support for the xSPI (Extended SPI) Interface on Renesas RZ/T2H and
RZ/N2H SoCs. The xSPI IP on these SoCs is identical to that found on the
RZ/G3E SoC.

v2->v3:
- Used RZ/G3E comptiable as a fallback compatible for
  RZ/T2H and RZ/N2H SoCs since the xSPI IP is identical.
- Updated commit message to reflect that the xSPI IP is
 identical between RZ/G3E, RZ/T2H, and RZ/N2H SoCs.
- Dropped RB tag from Rob for patch#1.
- Dropped driver changes for RZ/T2H and RZ/N2H SoCs since
  the xSPI IP is compatible to RZ/G3E.

v1->v2:
- Add RB tag from Rob for the dt-bindings patch.
- Add RB tag from Wolfram for the rpc-if duplicate device name patch.
- Added xspi_info_r9a09g077 for RZ/T2H with type XSPI_RZ_T2H instead
  of reusing xspi_info_r9a09g047 with type XSPI_RZ_G3E, to allow for
  better differentiation in the future if needed.

v2: https://lore.kernel.org/all/20260327174245.3947213-1-prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx/
v1: https://lore.kernel.org/all/20260310212927.3372410-1-prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx/

Note, patches apply on to of next-20260326

Cheers,
Prabhakar
