From cbba17870881cd17bca24673ccb72859431da5bd Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Thu, 26 Aug 2021 15:19:39 +0200 Subject: [PATCH] riscv: dts: microchip: mpfs-icicle: Fix serial console 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.
