If anyone has any objections, please let me know. ------------------ From: Conor Dooley commit e6c5d6c589764a41218cbd81bd7d6c9b906e2cf0 upstream. The bank voltages are only 4 bits wide, so when a pin was unused the driver was not correctly interpreting it as being at zero volts, because the driver's value for unused had two extra set bits.
