From 634852d1f468ccc8cc2e790757c6c1c0f95eb955 Mon Sep 17 00:00:00 2001 From: Ramalingam C Date: Mon, 4 Feb 2019 21:14:40 +0530 Subject: [PATCH] drm/i915: HDCP state handling in ddi_update_pipe The downgrade of the fullmodeset into fastset intel_encoder->update_pipe, in possible scenario, skips the En/Dis-able DDI. Hence breaks the HDCP state change handling. We also don't have any hdcp tests in CI, because the shard runs don't have hdcp capable outputs :-/ So this change fixs it by handling the HDCP state change request at intel_encoder->update_pipe too along with enable and disable of the DDI.
