Laurent Pinchart 333d2da5b7 drm: WARN when calling drm_format_info() for an unsupported format
The format helpers have historically treated unsupported formats as part
of the default case, returning values that are likely wrong. We can't
change this behaviour now without risking breaking drivers in difficult
to detect ways, but we can WARN on unsupported formats to catch faulty
callers.

The only exception is the framebuffer_check() function that calls
drm_format_info() to validate the format passed from userspace. This is
a valid use case that shouldn't generate a warning.

Laurent Pinchart d549349007 drm: Use drm_format_info() in DRM core code
Replace calls to the drm_format_*() helper functions with direct use of
the drm_format_info structure. This improves efficiency by removing
duplicate lookups.

Daniel Vetter 43968d7b80 drm: Extract drm_plane.[hc]
Just pure code movement, cleanup and polish will happen in later
patches.

v2: Don't forget all the ioctl! To extract those cleanly I decided to
put check_src_coords into drm_framebuffer.c (and give it a
drm_framebuffer_ prefix), since that just checks framebuffer
constraints.

v3: rebase over PAGE_FLIP_TARGET.

    drm: Reject page_flip for !DRIVER_MODESET

so as a result of moving the page_flip ioctl, this fix has
been rolled into this patch.

- Move the intro section into a DOC comment, and update it slightly.
- kernel-doc for struct drm_framebuffer!

v2:
- Copypaste fail (Sean).
- Explain the linear @offsets clearer (Ville).

Daniel Vetter 7520a277d9 drm: Extract drm_framebuffer.[hc]
Also start with drm_modeset.h with the core bits, since we need
to untangle this mess somehow. That allows us to move the drm_modes.h
include to the right spot, except for the temporary connector status
enum. That will get fixed as soon as drm_connector.h exists.

v2: Rebase.

v3: Move drm_crtc_force_disable_all back again, that wasn't meant to
be moved (Sean).

v4: Rebase.
