If anyone has any objections, please let me know. ------------------ From: Quentin Schulz commit dfe078755706ed50651ebbe0442843ecd4ae8389 upstream. According to the Jedec 5.1 specification, the device is held in reset when RST_n is low, therefore the polarity of the line must be that, as specified in the Device Tree binding (mmc/mmc-pwrseq-emmc.yaml). Due to the wrong polarity, eMMC devices with RST_n_FUNCTION[162] bitfield [1:0] set to 0x1 (the default is 0x0) will be held in reset forever.
