Subject: [PATCH 3/3] MIPS: Loongson: Add log before power off due to high temperature
Date: Fri,  8 May 2020 19:55:04 +0800	[thread overview]
Message-ID: <1588938904-924-4-git-send-email-yangtiezhu@loongson.cn> (raw)
In-Reply-To: <1588938904-924-1-git-send-email-yangtiezhu@loongson.cn>

When the CPU temperature is too high, it is better to print a log before
power off, this is useful when analysis the abnormal issues.
