Patch 1 updates the Device Tree binding schema for the Microchip LAN8650/1 to document the optional reset-gpios property connected to the active-low RESET_N pin. Patch 2 implements optional reset GPIO handling in the common oa_tc6 library. If specified, the hardware reset line is asserted for 10 us (datasheet specifies min 5 us) and allowed 1 ms settle time for crystal oscillator startup before starting OPEN Alliance TC6 communication. Changes in v2: - Moved reset-gpios handling from the lan865x driver into the common oa_tc6 library (drivers/net/ethernet/oa_tc6.c), so all MAC-PHY devices can make use of it, as suggested by Parthiban Veerasooran.
