-Subject: [PATCH] LF-605 mmc: sdhci-of-esdhc: update tuning erratum A-008171
-
-There is an official update for eSDHC tuning erratum A-008171.
-This patch is to implement the changes,
-- Affect all revisions of SoC.
-- Changes for tuning window checking.
-- Hardware hits a new condition that tuning succeeds although
-  the eSDHC might not have tuned properly for type2 SoCs
-  (soc_tuning_erratum_type2[] array in driver). So check
-  tuning window after tuning succeeds.
