From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com> Hi All, - RZ/G2UL and RZ/Five ("r9a07g043") - RZ/G2L(C) ("r9a07g044") - RZ/V2L ("r9a07g054") - RZ/G3S ("r9a08g045") - RZ/V2M ("r9a09g011") The SD/MMC Interface in the above listed SoCs is not identical to that of R-Car Gen3. These SoCs have HS400 disabled and use fixed address mode. Therefore, we need to apply fixed_addr_mode and hs400_disabled quirks. 'renesas,rzg2l-sdhi' is introduced as a generic compatible string for the above SoCs where fixed_addr_mode and hs400_disabled quirks will be applied. v1->v2 - Updated commit messages for patch #1 and #2 - Dropped SoC DTSI changes as its a hard dependency - Grouped single const value items into an enum list. - For backward compatibility retained RZ/V2M compat string v1: https://patchwork.kernel.org/project/linux-renesas-soc/cover/20240422213006.505576-1-prabhakar.mahadev-lad.rj@bp.renesas.com/ Cheers, Prabhakar Lad Prabhakar (3): dt-bindings: mmc: renesas,sdhi: Group single const value items into an enum list dt-bindings: mmc: renesas,sdhi: Document RZ/G2L family compatibility mmc: renesas_sdhi: Add compatible string for RZ/G2L family, RZ/G3S, and RZ/V2M SoCs .../devicetree/bindings/mmc/renesas,sdhi.yaml | 38 ++++++++----------- drivers/mmc/host/renesas_sdhi_internal_dmac.c | 9 +++-- 2 files changed, 21 insertions(+), 26 deletions(-)
