From 4233698dd37536f2595ec773ca841360195cd310 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Sat, 19 Jan 2019 01:30:53 +0000 Subject: [PATCH] mmc: sunxi: Honour non-removable property in DT If a board DT describes a cd-gpios property, but also marks the storage as non-removable, we must ignore the GPIO (as Linux does). Teach the DM_MMC part of the Allwinner MMC driver about the non-removable DT property, to fix DM_MMC access on the SoPine and Pine64-LTS board.
