+Subject: drm/bridge: lt9611: Fix PLL being unable to lock
+
+From: Robert Foss <robert.foss@linaro.org>
+
+commit 2a9df204be0bbb896e087f00b9ee3fc559d5a608 upstream.
+
+This fixes PLL being unable to lock, and is derived from an equivalent
+downstream commit.
+
+Available LT9611 documentation does not list this register, neither does
+LT9611UXC (which is a different chip).
+
+This commit has been confirmed to fix HDMI output on DragonBoard 845c.
