[PATCH] mmc: sdhci-of-dwcmshc: Use inverted-wp quirk for CV18xx and SG200x SoCs

From: Haylen Chu
Date: Fri May 31 2024 - 10:20:45 EST


MMC controller integrated in Sophgo CV18xx and SG200x SoCs has an
inverted write-protect flag, causing SDCards misdetected as read-only.
So set SDHCI_QURIK_INVERTED_WRITE_PROTECT to make write protection work
correctly.

Fixes: 017199c2849c ("mmc: sdhci-of-dwcmshc: Add support for Sophgo CV1800B and SG2002")
