X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2b29bf16611a1aabb310406dd171dce6e6d51322;p=linux-beck.git 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.
