- Board specific DT entries for TI's USIM - smart card controller of AM43xx
platfrom.These entries are used by USIM driver for various configurations.
- Shutdown line of NXP phy is maped to GPIO5. So enabling same to have support
for NXP phy.
- i2c2 pinmux configuration - NxP tda8026 phy is connected to i2c2 lines
