Subject: [PATCH v3 0/3] tty: serial: Add earlycon support to MT8173 SoC
Date: Tue, 28 Apr 2015 21:40:31 +0800 [thread overview]
Message-ID: <1430228434-31779-1-git-send-email-eddie.huang@mediatek.com> (raw)
This patch add earlycon support to MT8173 SoC platform.
To use earlycon, need
1. Add earlycon in boot parameters
2. Add "linux,sdtout-path" property in device tree file
This patch based on 4.1-rc1.
Change in v3:
Remove noinit options, not necessary, because 8250_early.c will not init hardware
if not provide baudrate.
Change v2:
1. Add noinit options.
2. Remove duplicate code in 8250_mtk.c, reuse the 8250_early.c existed function.
