[PATCH AUTOSEL 5.10 09/47] mmc: sdhci-of-dwcmshc: set SDHCI_QUIRK2_PRESET_VALUE_BROKEN

From: Sasha Levin <sashal@kernel.org>
Date: 2021-03-02 16:07:10
Also in: linux-mmc, lkml
Subsystem: multimedia card (mmc), secure digital (sd) and sdio subsystem, secure digital host controller interface (sdhci) driver, the rest · Maintainers: Ulf Hansson, Adrian Hunter, Linus Torvalds

From: Jisheng Zhang <redacted>

[ Upstream commit 5f7dfda4f2cec580c135fd81d96a05006651c128 ]

The SDHCI_PRESET_FOR_* registers are not set(all read as zeros), so
set the quirk.
