Hi Daniel,
Sorry for the trouble. I think you were saying below patch introduced issue for you. fe0acab mmc: sdhci-of-esdhc: fix P2020 errata handling
Actually it looked fine from code. Probably it resolved its own issue but caused another. I don't know which kernel you were using. Could you have a check whether my other fix-up patches which may be related to P2020 in your kernel after that one? I remembered P2020 should work.
80c7482 mmc: sdhci-of-esdhc: fix serious issue clock is always disabled 429d939 mmc: sdhci-of-esdhc: fix transfer mode register reading 1b21a70 mmc: sdhci-of-esdhc: fix clock setting for different controller versions 2aa3d82 mmc: sdhci-of-esdhc: fix esdhc_reset() for different controller versions f667216 mmc: sdhci-of-esdhc: re-implement erratum A-009204 workaround
Thanks a lot.
Best regards, Yangbo Lu

Hi,
We got your patch from stable. On p2020 we had mmc issues, and bisected the issue to your patch.
Both prior patches seems to modify quirks2.
Fixes: 05cb6b2a66fa ("mmc: sdhci-of-esdhc: add erratum eSDHC-A001and A-008358 support") Fixes: a46e42712596 ("mmc: sdhci-of-esdhc: add erratum eSDHC5 support")
So I'm not sure if your changes were done correctly.
Daniel
