From 2b29bf16611a1aabb310406dd171dce6e6d51322 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 28 Sep 2016 17:21:05 -0700 Subject: [PATCH] drm/vc4: Increase timeout for HDMI_SCHEDULER_CONTROL changes. Fixes occasional debug spew at boot when connected directly through HDMI, and probably confusing the HDMI state machine when we go trying to poke registers for the enable sequence too soon.
