    Subject[PATCH 03/12] ARM: dts: sun8i: Add pinmux set for uart0
    Date
    uart0 on sun8i is only muxed with mmc0, which makes it a poor choice
    for the console. However, some tablets only have pads for uart0
    available on the circuit board.

    Here we add the uart0 pinmux set for people who need it.
