Subject: [PATCH AUTOSEL 5.8 49/72] arm64: dts: meson: misc fixups for w400 dtsi
Date: Sat, 8 Aug 2020 19:35:18 -0400 [thread overview]
Message-ID: <20200808233542.3617339-49-sashal@kernel.org> (raw)
In-Reply-To: <20200808233542.3617339-1-sashal@kernel.org>
From: Christian Hewitt <christianshewitt@gmail.com>
[ Upstream commit 2fa17dd09533d5d83201be3229a28c1010a8ea3e ]
Current devices using the W400 dtsi show mmc tuning errors:
[12483.917391] mmc0: tuning execution failed: -5
[30535.551221] mmc0: tuning execution failed: -5
[35359.953671] mmc0: tuning execution failed: -5
[35561.875332] mmc0: tuning execution failed: -5
[61733.348709] mmc0: tuning execution failed: -5
Removing "sd-uhs-sdr50" from the SDIO node prevents this. We also add
keep-power-in-suspend to the SDIO node and fix an indentation.
Fixes: 3cb74db9b256 ("arm64: dts: meson: convert ugoos-am6 to common w400 dtsi")
