<content type='text'>
drm_crtc.h has no need for drm_frambuffer.h, so don't include it.
Avoids useless rebuilds of the entire universe when
touching drm_framebuffer.h.

Quite a few placs do currently depend on drm_framebuffer.h without
actually including it directly. All of those need to be fixed
up.

v2: Fix up msm some more
v2: Deal with ingenic and shmobile as well

<title>drm/format-helper: Rename drm_fb_xrgb8888_to_mono_reversed()</title>

<id>urn:sha1:9b13a3fcd35fc24045d2fd0f0e13ddd8d7985b4b</id>
<content type='text'>
There is no "reversed" handling in drm_fb_xrgb8888_to_mono_reversed():
the function just converts from color to grayscale, and reduces the
number of grayscale levels from 256 to 2 (i.e. brightness 0-127 is
mapped to 0, 128-255 to 1).  All "reversed" handling is done in the
repaper driver, where this function originated.

Hence make this clear by renaming drm_fb_xrgb8888_to_mono_reversed() to
drm_fb_xrgb8888_to_mono(), and documenting the black/white pixel
mapping.

There is now a drm_fb_xrgb8888_to_mono_reversed() helper function to do
format conversion from XRGB8888 to reversed monochrome.

Use that helper and remove the open coded version in the repaper driver.

<title>spi: make remove callback a void function</title>

<content type='text'>
The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

Move destination-buffer clipping from all format-helper conversion
functions into callers. Support destination-buffer pitch. Only
distinguish between system and I/O memory, but use same logic
everywhere.

Simply harmonize the interface and semantics of the existing code.
Not all conversion helpers support all combinations of parameters.
We have to add additional features when we need them.

v2:
	* fix default destination pitch in drm_fb_xrgb8888_to_gray8()

<content type='text'>
The function drm_gem_fb_prepare_fb() is a helper for atomic modesetting,
but currently located next to framebuffer helpers. Move it to GEM atomic
helpers, rename it slightly and adopt the drivers. Same for the rsp
simple-pipe helper.

Compile-tested with x86-64, aarch64 and arm. The patch is fairly large,
but there are no functional changes.

v3:
	* remove out-comented line in drm_gem_framebuffer_helper.h
	  (Maxime)
v2:
	* rename to drm_gem_plane_helper_prepare_fb() (Daniel)
	* add tutorial-style documentation
