[PATCH] mmc: core: add mmc-card hardware reset enable support

2017-04-04 Thread Richard Leitner
Some eMMCs disable their hardware reset line (RST_N) by default. To enable it the host must set the corresponding bit in ECSD. An example for such a device is the Micron MTFCxGACAANA-4M. This patch adds a new mmc-card devicetree property to let the host enable this feature during card initializati
