From: Eugen Hristev Date: Thu, 8 Aug 2019 08:35:40 +0000 (+0000) Subject: mmc: sdhci-of-at91: add quirk for broken HS200 X-Git-Tag: v4.9.191~11 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f0d3242a1211c2f12a6da93c97e6b2c4861aba88;p=platform%2Fkernel%2Flinux-amlogic.git mmc: sdhci-of-at91: add quirk for broken HS200 commit 7871aa60ae0086fe4626abdf5ed13eeddf306c61 upstream. HS200 is not implemented in the driver, but the controller claims it through caps. Remove it via a quirk, to make sure the mmc core do not try to enable HS200, as it causes the eMMC initialization to fail.
