[PATCH 1/2] mmc: sdhci-of-at91: add quirk for broken HS200
From: <hidden>
Date: 2019-08-08 08:35:47
Also in:
linux-devicetree, linux-mmc, lkml
Subsystem:
multimedia card (mmc), secure digital (sd) and sdio subsystem, secure digital host controller interface (sdhci) driver, secure digital host controller interface (sdhci) microchip driver, the rest · Maintainers:
Ulf Hansson, Adrian Hunter, Aubin Constans, Linus Torvalds
From: Eugen Hristev <redacted> HS200 is not implemented in the driver, but the controller claims it through caps. Remove it via quirk. Without this quirk, the mmc core will try to enable hs200, which will fail, and the eMMC initialization will fail.
