The PCIEPHY_PERST bit is already supported by the driver (albeit incorrectly?) - this patch just inverts the bit. Since this bit is not inverted on the other platforms, and the i.MX8MP reference manual says nothing about this, please explicitly state why this needs to be inverted and call it a fix in the commit description. regards Philipp
