From: Chris Morgan <macromor...@hotmail.com> Backport fixes for the Potron SFP+ XGSPON ONU stick. These fixes allow the Potron SFP+ XGSPON ONU stick to work without manual workarounds to prevent UART activity on pins 2 and 7 to be interpreted as TX_FAULT or LOS signals on devices with support for these signals (such as the Banana Pi R4).
