I guess you could fold that patch into the previous one.

Is there any other UART in the system?

serial0 is defined in sun8i-reference-design-tablet.dtsi, as r_uart.

The alias is not supposed to be about the controller index, but the
index in the board, meaning that if you only have a single UART, that
would be serial0.

Thanks!
