[PATCH v3 2/5] mmc: sdhci-pxav3: enable usage of DAT3 pin as HW card detect

2015-10-15 Thread Marcin Wojtas
Marvell Armada 38x SDHCI controller enable using DAT3 pin as a hardware card detection. According to the SD sdandard this signal can be used for this purpose combined with a pull-down resistor, implying inverted (active high) polarization of a card detect. MMC standard does not support this feature
