Instead of giving -1 to as arg to drm_send_vblank_event() pass the correct pipe number to it.

Get rid of legacy DRM vblank function that are less clear to use. The new ones basically requires only the crtc as parameters.

It also clean ups exynos_drm_crtc_finish_pageflip() parameters as a consequence.

The atomic modesetting interfaces supports async commits that should be implemented by the drivers. If drm core requests an async commit exynos_atomic_commit() will schedule a work task to run the update later.

It also waits an update to finish before schedule a new one.

We already have the plane pointer in before calling .update_plane() or disable_plane() so pass it directly to those calls avoiding a new conversion from zpos to struct exynos_drm_plane.

v2: don't remove check for suspended in FIMD (comment by Joonyoung)

Now after the move to use drm_plane_state directly struct drm_plane_state has many unused fields, along with others that weren't used before the plane state change. Thus remove them all.

The DRM Core doesn't have a dpms() operation anymore, everything now is enable() or disable().

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.

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.

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.

From: Gustavo Padovan gustavo.padovan@collabora.co.uk

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.
