* [PATCH v2 1/3] mmc: renesas_sdhi: Add OF entry for RZ/G2H SoC [not found] <20260519135342.623943-1-prabhakar.mahadev-lad.rj@bp.renesas.com> @ 2026-05-19 13:53 ` Prabhakar 2026-05-19 16:09 ` Wolfram Sang 2026-05-20 7:56 ` Geert Uytterhoeven 0 siblings, 2 replies; 3+ messages in thread From: Prabhakar @ 2026-05-19 13:53 UTC (permalink / raw) To: Wolfram Sang, Ulf Hansson, Geert Uytterhoeven, Magnus Damm Cc: linux-mmc, linux-renesas-soc, linux-kernel, Prabhakar, Biju Das, Fabrizio Castro, Lad Prabhakar, stable From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com> The RZ/G2H (R8A774E1) SoC was previously handled via the generic "renesas,rcar-gen3-sdhi" fallback compatible string. However, because the SDHI IP on RZ/G2H is identical with the R-Car H3-N (R8A77951), it requires the specific quirks and configuration defined in `of_r8a7795_compatible` rather than the generic Gen3 data. Add the explicit "renesas,sdhi-r8a774e1" match entry to map it correctly. Note that the DT binding file renesas,sdhi.yaml does not need an update as the entry for this SoC is already present.
