From 7871aa60ae0086fe4626abdf5ed13eeddf306c61 Mon Sep 17 00:00:00 2001 From: Eugen Hristev Date: Thu, 8 Aug 2019 08:35:40 +0000 Subject: mmc: sdhci-of-at91: add quirk for broken HS200 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.
