Subject: [PATCH] arm64: allwinner: dts: h6: fix Pine H64 MMC bus width
Date: Thu, 26 Jul 2018 12:48:05 +0800	[thread overview]
Message-ID: <20180726044805.55888-1-icenowy@aosc.io> (raw)

Currently the enabled MMC controllers on Pine H64 do not have bus-width
set, which make them fall back to 1-bit mode and become quite slow.

Fix this by add the corresponding bus-width properties.

Fixes: ecbd611882a1 ("arm64: allwinner: h6: enable MMC0/2 on Pine H64")
