From b5fa16b62042382a72e09d2a463fe41914f62b96 Mon Sep 17 00:00:00 2001 From: Icenowy Zheng Date: Tue, 20 Dec 2016 13:58:26 +0800 Subject: [PATCH] ARM: dts: sun8i: add a delay after reset xr819 on Orange Pi Zero XR819 seems to need a delay after its reset line to be deasserted, otherwise it may not respond MMC commands correctly, and fail to initialize. Add a 200ms delay in the mmc-pwrseq.
