Subject: [PATCH] mmc: sdhci-of-esdhc: re-implement erratum A-009204 workaround
The erratum A-009204 workaround patch was reverted because of
incorrect implementation.
8b6dc6b mmc: sdhci-of-esdhc: Revert "mmc: sdhci-of-esdhc: add
erratum A-009204 support"
This patch is to re-implement the workaround (add a 5 ms delay
before setting SYSCTL[RSTD] to make sure all the DMA transfers
are finished).
For 5.4 I took in 22dc132d5448 ("mmc: sdhci-of-esdhc: fix up erratum
A-008171 workaround") to resolve the conflict. I'm not sure if the above
patch is needed on older kernels.
