From 9142364e4666835e53586c21fe4e8983a8b09bb2 Mon Sep 17 00:00:00 2001 From: Archit Taneja Date: Mon, 16 Jan 2017 12:16:34 +0530 Subject: [PATCH] drm/msm/mdp5: Refactor mdp5_plane_atomic_check In mdp5_plane_atomic_check, we get crtc_state from drm_plane_state. Later, for cursor planes, we'll populate the update_plane() func that takes a fast asynchronous path to implement cursor movements. There, we would need to call a similar atomic_check func to validate the plane state, but crtc_state would need to be derived differently. Refactor mdp5_plane_atomic_check to mdp5_plane_atomic_check_with_state such that the latter takes crtc_state as an argument. This is similar to what the intel driver has done for async cursor updates.
