-Subject: [PATCH] mmc: xenon_sdhci: remove wait_dat0 SDHCI OP
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Generic SDHCI driver received support for checking the busy status by
-polling the DAT[0] level instead of waiting for the worst MMC switch time.
-
-Unfortunately, it appears that this does not work for Xenon controllers
-despite being a part of the standard SDHCI registers and the Armada 3720
-datasheet itself telling that BIT(20) is useful for detecting the DAT[0]
-busy signal.
-
-I have tried increasing the timeout value, but I have newer managed to
-catch DAT_LEVEL bits change from 0 at all.
-
-This issue appears to hit most if not all SoC-s supported by Xenon driver,
-at least A3720, A8040 and CN9130 have non working eMMC currently.
-
-So, until a better solution is found drop the wait_dat0 OP for Xenon.
-I was able to only test it on A3720, but it should work for others as well.
-
-Fixes: 40e6f52454fc ("drivers: mmc: Add wait_dat0 support for sdhci driver")
