From 38b8f823864707eb1cf331d2247608c419ed388c Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Wed, 3 May 2017 11:13:46 +0800 Subject: clk: sunxi-ng: a31: Correct lcd1-ch1 clock register offset 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.
