    Subject[PATCH 5.14 053/100] riscv: dts: microchip: mpfs-icicle: Fix serial console
    Date
    From: Geert Uytterhoeven <geert@linux-m68k.org>

    [ Upstream commit cbba17870881cd17bca24673ccb72859431da5bd ]

    Currently, nothing is output on the serial console, unless
    "console=ttyS0,115200n8" or "earlycon" are appended to the kernel
    command line. Enable automatic console selection using
    chosen/stdout-path by adding a proper alias, and configure the expected
    serial rate.

    While at it, add aliases for the other three serial ports, which are
    provided on the same micro-USB connector as the first one.
