Subject: [PATCH] clk: sunxi-ng: a31: Correct lcd1-ch1 clock register offset
Date: Wed,  3 May 2017 11:13:46 +0800	[thread overview]
Message-ID: <20170503031346.29174-1-wens@csie.org> (raw)

The register offset for the lcd1-ch1 clock was incorrectly pointing to
the lcd0-ch1 clock. This resulted in the lcd0-ch1 clock being disabled
when the clk core disables unused clocks. This then stops the simplefb
HDMI output path.

Reported-by: Bob Ham <rah@settrans.net>
Fixes: c6e6c96d8fa6 ("clk: sunxi-ng: Add A31/A31s clocks")
Cc: stable at vger.kernel.org # 4.9.x-
