Subject: [PATCH 5/5] serial: sprd: adjust TIMEOUT to a big value
Date: Tue, 14 Feb 2017 17:19:12 +0800 [thread overview]
Message-ID: <1487063952-7113-6-git-send-email-chunyan.zhang@spreadtrum.com> (raw)
In-Reply-To: <1487063952-7113-1-git-send-email-chunyan.zhang@spreadtrum.com>
From: Wei Qiao <wei.qiao@spreadtrum.com>
SPRD_TIMEOUT was 256, which is too small to wait until the status
switched to workable in a while loop, so that the earlycon could
not work correctly.
