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
Yes, this patch cased mmc to stop functioning on p2020.
Have you investigated this ?
As I said, this patch was proper fix-up, fixing mistake which used host->quirks2. It was host->quirks that should be used. But after this patch, the other potential issues for P2020 appeared.
Your including a change into stable which breaks p2020, that's not acceptable. If more changes are needed to make p2020 stable can you send those additional patches to stable also ?
Otherwise we need to revert your current patch.
Daniel
