From 4ec9dd4071cb3e7d2c0c42f2eea935edceba5b7e Mon Sep 17 00:00:00 2001 From: Pierre Bourdon Date: Thu, 11 Apr 2019 04:56:58 +0200 Subject: [PATCH] mmc: mv_sdhci: add driver model support The new DM implementation currently does not support the Sheeva 88SV331xV5 specific quirk present in the legacy implementation. The legacy code is thus kept for this SoC and others not yet migrated to DM_MMC.
