From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Fabrizio Castro Subject: [PATCH 1/6] dt-bindings: mmc: renesas_sdhi: Add r8a77470 support Date: Wed, 3 Oct 2018 12:05:39 +0100 Message-Id: <1538564744-15590-2-git-send-email-fabrizio.castro@bp.renesas.com> In-Reply-To: <1538564744-15590-1-git-send-email-fabrizio.castro@bp.renesas.com> References: <1538564744-15590-1-git-send-email-fabrizio.castro@bp.renesas.com> To: Ulf Hansson , Rob Herring , Simon Horman , Geert Uytterhoeven , Mark Rutland Cc: Fabrizio Castro , linux-mmc@vger.kernel.org, devicetree@vger.kernel.org, Chris Paterson , Biju Das , linux-renesas-soc@vger.kernel.org List-ID: 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.
