As many RPI2 styled interfaces provides 1 or 2 UARTs.

Non necessarily ... There is a second UART, the UART4 available on pins 19/21, but it is shared with SPI pins.
It is better to use those SPI pins for attaching the SC16IS752 chips ...
Hi, I just obtained my first Rock64, may i know how to enable SPI pin with SC16IS752 step by step in Linux?
