+Subject: [PATCH 2/3] ARM: clk-imx6q: fix video divider for rev T0 1.0
+
+commit 81ef447950bf0955aca46f4a7617d8ce435cf0ce upstream.
+
+The post dividers do not work on i.MX6Q rev T0 1.0 so they must be fixed
+to 1. As the table index was wrong, a divider a of 4 could still be
+requested which implied the clock not to be set properly. This is the
+root cause of the HDMI not working at high resolution on rev T0 1.0 of
+the SoC.
