From c3d62fc6a058d1024f3ad0525a251e9d6c5203ed Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Fri, 2 Jun 2017 12:29:53 -0700 Subject: MIPS: generic/yamon-dt: Use serial* rather than uart* aliases Name aliases in the SEAD-3 device tree serial0 & serial1, rather than uart0 & uart1. This allows the core serial code to make use of the aliases to ensure that the UARTs are consistently numbered as expected rather than having the numbering depend upon probe order. When translating YAMON-provided serial configuration to a device tree stdout-path property adjust accordingly, such that we continue to reference a valid alias.
