2017-10-17drm/amd/display: Unify amdgpu_dm state variable namings.Leo (Sunpeng) Li1-69/+68
Use dm_new_*_state and dm_old_*_state for their respective amdgpu_dm new and old object states. Helps with readability, and enforces use of new DRM api (choose either new, or old).

2017-10-17drm/amd/display: Use new DRM API where possibleLeo (Sunpeng) Li1-65/+66
To conform to DRM's new API, we should not be accessing a DRM object's internal state directly. Rather, the DRM for_each_old/new_* iterators, and drm_atomic_get_old/new_* interface should be used. This is an ongoing process. For now, update the DRM-facing atomic functions, where the atomic state object is given.

2017-10-17drm/amd/display: Use DRM new-style object iterators.Dave Airlie2-28/+17
Use the correct for_each_new/old_* iterators instead of for_each_* The following functions were considered: amdgpu_dm_find_first_crtc_matching_connector: use for_each_new - Old from_state_var flag was always choosing the new state amdgpu_dm_display_resume: use for_each_new - drm_atomic_helper_duplicate_state is called during suspend to cache the state - It sets 'state' within the state triplet to 'new_state' amdgpu_dm_commit_planes: use for_each_old - Called after the state was swapped (via atomic commit tail) amdgpu_dm_atomic_commit: use for_each_new - Called before the state is swapped amdgpu_dm_atomic_commit_tail: use for_each_old - Called after the state was swapped dm_update_crtcs_state: use for_each_new - Called before the state is swapped (via atomic check) amdgpu_dm_atomic_check: use for_each_new - Called before the state is swapped v2: Split out typo fixes to a new patch. v3: Say "functions considered" instead of "affected functions". The latter implies that changes are made to each.
