Subject: [PATCH V3 4/4] serial: sprd: adjust TIMEOUT to a big value
Date: Thu, 2 Mar 2017 14:22:10 +0800 [thread overview]
Message-ID: <1488435730-6711-5-git-send-email-chunyan.zhang@spreadtrum.com> (raw)
In-Reply-To: <1488435730-6711-1-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.
