Hi, If "default" pins are active for CAN then there is a slight window during boot when CAN pins are in active mode and can affect DRA7 CAN stability. This is because device core automatically selects "default" before probe.
These patches change "default" pins to inactive and adds a new "active" pin state so that we don't encounter the glitch mentioned above. cheers, -roger J.D.
