From 50e9d6cb5dbfec87b39f7d6f270841328f9ba555 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Thu, 3 Sep 2020 10:01:04 +0200 Subject: drm/vc4: hvs: Make the stop_channel function public During the transition from the firmware to the KMS driver, we need to pay particular attention to how we deal with the pixelvalves that have already been enabled, otherwise either timeouts or stuck pixels can occur. We'll thus need to call the function to stop an HVS channel at boot.
