From 60ab43ba6b6e0f888aab3ce0f84a8aaf15d15079 Mon Sep 17 00:00:00 2001 From: Fabrizio Castro Date: Mon, 8 Oct 2018 09:51:49 +0100 Subject: [PATCH] mmc: renesas_sdhi: Add r8a77470 SDHI1 support 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.
