Subject: [PATCH V2 3/3] serial: sprd: adjust TIMEOUT to a big value
Date: Tue, 21 Feb 2017 14:55:04 +0800 [thread overview]
Message-ID: <1487660104-15693-4-git-send-email-chunyan.zhang@spreadtrum.com> (raw)
In-Reply-To: <1487660104-15693-1-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.
