[RFC PATCH 2/2] mmc: sdhci: Quirk for AMD SDHC Device 0x7906

2019-05-01 Thread Raul E Rangel
AMD SDHC 0x7906 requires a hard reset to clear all internal state. Otherwise it can get into a bad state where the DATA lines are always read as zeros. This change requires firmware that can transition the device into D3Cold for it to work correctly. If the firmware does not support transitioning
