Subject: [PATCH 3/6] mmc: renesas_sdhi: Add r8a77470 SDHI1 support
Date: Wed,  3 Oct 2018 12:05:41 +0100	[thread overview]
Message-ID: <1538564744-15590-4-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 the R-Car Gen2 SDHIs, SDHI1
is compatible with R-Car Gen3 SDHIs and it can be used as
eMMC as well. This patch adds driver compatibility, and makes
sure both drivers get compiled for the R8A77470.
