94e30d93f9 drm/exynos: remove exynos_drm_fb_set_buf_cnt()
The exynos_drm_fb_set_buf_cnt() is used to set buffer count only in
exynos_drm_fbdev_update(). This patch sets directly buffer count in
exynos_drm_framebuffer_init() without using exynos_drm_fb_set_buf_cnt(),
so there is no any reason to keep exynos_drm_fb_set_buf_cnt().

179239a7ae drm/exynos: fix size check in g2d_check_buf_desc_is_valid()
The size check was incomplete. It only computed the
size of area of the drawing rectangle and checked if
the size still fit inside the buffer.

The correct check is to compute the position of the
last byte that the G2D engine is going to access and
then check if that position is still contained in the
buffer. In particular we need the stride information
to determine this.

The current code was ignoring the end of update for all overlay planes,
caring only for the primary plane update in case of pageflip.

This change adds a change to start to check for pending updates for all
planes through exynos_plane->pending_fb. At the start of plane update the
pending_fb is set with the fb to be shown on the screen. Then only when to
fb is already presented in the screen we set pending_fb to NULL to
signal that the update was finished.

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

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

2eeb2e5e66 drm/exynos: use drm atomic state directly
For some fields the use of struct exynos_drm_plane filled with data from
the plane state just creates a source of duplicated information and
overhead.  Here we change the crtc drivers to access the plane state
directly simplifying the code by not relying on a exynos internal struct.

1e1d139322 drm/exynos: pass struct exynos_drm_plane in update/enable
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.

eafd540aea drm/exynos: use KMS version of DRM vblanks functions
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.
