Subject: [PATCH 1/6] dt-bindings: mmc: renesas_sdhi: Add r8a77470 support
Date: Wed,  3 Oct 2018 12:05:39 +0100	[thread overview]
Message-ID: <1538564744-15590-2-git-send-email-fabrizio.castro@bp.renesas.com> (raw)
In-Reply-To: <1538564744-15590-1-git-send-email-fabrizio.castro@bp.renesas.com>

The RZ/G1C (a.k.a. R8A77470) comes with three SDHI interfaces,
SDHI0 and SDHI2 are compatible with R-Car Gen2 SDHIs, and
SDHI1 is compatible with R-Car Gen3 SDHIs, as it comes with an
internal DMAC, therefore SDHI1 is fully compatible with driver
renesas_sdhi_internal_dmac driver. As a result, the compatible
strings for the R8A77470 SDHI interfaces are a little bit special.
Document SDHI support for the RZ/G1C SoC.
