From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Fabrizio Castro Subject: [PATCH 4/6] ARM: dts: r8a77470: Add SDHI0 support Date: Wed, 3 Oct 2018 12:05:42 +0100 Message-Id: <1538564744-15590-5-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: Rob Herring , Simon Horman , Geert Uytterhoeven , Mark Rutland Cc: Fabrizio Castro , Magnus Damm , linux-renesas-soc@vger.kernel.org, devicetree@vger.kernel.org, Chris Paterson , Biju Das List-ID: RZ/G1C comes with two different types of IP for the SDHI interfaces, SDHI0 and SDHI2 share the same IP type, and such an IP is also compatible with the one found in R-Car Gen2. SDHI1 IP on the other hand is compatible with R-Car Gen3 with internal DMA. This patch completes the SDHI support of the R-Car Gen2 compatible IPs, including fixing the max-frequency definition of SDHI2, as it turns out there is a bug in Section 1.3.9 of the RZ/G1C Hardware User's Manual (Rev. 1.00 Oct. 2017).
