Subject: [v5.5] Fix up eSDHC issue on P2020
Date: Wed, 15 Apr 2020 11:52:11 +0800 [thread overview]
Message-ID: <20200415035212.19139-1-yangbo.lu@nxp.com> (raw)
The upstream commit broke P2020 eSDHC.
fe0acab mmc: sdhci-of-esdhc: fix P2020 errata handling
While the issue was fixed by later commit.
2aa3d82 mmc: sdhci-of-esdhc: fix esdhc_reset() for different controller versions
The commit fe0acab had been applied to stable kernel 5.5, 5.4,
4.19, 4.14, 4.9, and 4.4 without that fix-up.
To fix up P2020 eSDHC on the stable kernels, backport the fix-up 2aa3d82
kernel 5.4 and 5.5.
Please help to revert fe0acab on 4.19, 4.14, 4.9 and 4.4, since there are
many conflicts to cherry-pick the fix-up, and fe0acab is actually not strongly
required for handling errata which is hardly triggered.
