Subject[PATCH v2 3/5] mmc: sdhci-sprd: add SDHCI_QUIRK2_PRESET_VALUE_BROKEN
Date
From: Chunyan Zhang <chunyan.zhang@unisoc.com>

The bit of PRESET_VAL_ENABLE in HOST_CONTROL2 register is reserved on
sprd's sd host controller, set quirk2 to disable configuring this.

Fixes: fb8bd90f83c4 ("mmc: sdhci-sprd: Add Spreadtrum's initial host
controller")
