2015-08-16drm/exynos: stop copying sg tableJoonyoung Shim3-40/+20

2015-08-16drm/exynos: remove struct exynos_drm_encoder layerGustavo Padovan15-309/+259
struct exynos_drm_encoder was justing wrapping struct drm_encoder, it had only a drm_encoder member and the internal exynos_drm_encoders ops that was directly mapped to the drm_encoder helper funcs. So now exynos DRM uses struct drm_encoder directly, this removes completely the struct exynos_drm_encoder. v2: add empty .mode_fixup() and .mode_set() to DSI and DPI to avoid null pointer.

2015-08-16drm/exynos: remove exynos_drm_create_enc_conn()Gustavo Padovan11-69/+101
This functions was just hiding the encoder and connector creation in a way that was less clean than if we get rid of it. For example, exynos_encoder ops had .create_connector() defined only because we were handing off the encoder and connector creation to exynos_drm_create_enc_conn(). Without this function we can directly call the create_connector function internally in the code, without the need of any vtable access. It also does some refactoring in the code like creating a bind function for dpi devices.

2015-08-16drm/exynos: remove exynos_encoder's .commit() opGustavo Padovan2-5/+0

2015-08-16drm/exynos: remove extra call to exynos_dp_commit()Gustavo Padovan1-4/+3
exynos_dp_commit() was getting called twice by exynos encoder core, once inside the .enable() call and another time by .commit() itself. The remove of the second call caused the wake of a bug, the operations orders inside exynos_dp_commit was wrong and we had to move exynos_dp_start_video() to be the last operation in there.

2015-08-16drm/exynos: remove struct exynos_drm_displayGustavo Padovan14-252/+177
This struct was just representing encoder information, it was a member of struct exynos_drm_encoder, so any code trying to access encoder data would have to go through the encoder struct, get the display struct and then get the data it want. During this patchset we also realized that the only data exynos_drm_encoder needs to store is the drm_encoder parent and the exynos_drm_encoder_ops.

2015-08-16drm/exynos: simplify calculation of possible CRTCsGustavo Padovan1-24/+5

2015-08-16drm/exynos: use drm atomic state directlyGustavo Padovan5-75/+75
