Thomas Zimmermann bc50cf64e9 drm/kmb: Remove unnecessary include statements for drm_crtc_helper.h
Several source files include drm_crtc_helper.h without needing it or
only to get its transitive include statements; leading to unnecessary
compile-time dependencies.

Drop drm_crtc_helper.h where possible.

v2:
	* update commit message (Sam)

Anitha Chrisanthus a79f40cccd drm/kmb: Limit supported mode to 1080p
KMB only supports single resolution(1080p), this commit checks for
1920x1080x60 or 1920x1080x59 in crtc_mode_valid.
Also, modes with vfp < 4 are not supported in KMB display. This change
prunes display modes with vfp < 4.

v2: added vfp check

Anitha Chrisanthus 7f7b96a8a0 drm/kmb: Add support for KeemBay Display
This is a basic KMS atomic modesetting display driver for KeemBay family of
SOCs. Driver has no 2D or 3D graphics. It calls into the ADV bridge
driver at the connector level.

Single CRTC with LCD controller->mipi DSI->ADV bridge

Only 1080p resolution and single plane is supported at this time.
