Series arch: Remove fbdev dependency from video helpers | expand

Commit Message

Thomas Zimmermann March 27, 2024, 8:41 p.m. UTC
The per-architecture fbdev code has no dependencies on fbdev and can
be used for any video-related subsystem. Rename the files to 'video'.
Use video-sti.c on parisc as the source file depends on CONFIG_STI_CORE.

Further update all includes statements, includ guards, and Makefiles.
Also update a few strings and comments to refer to video instead of
fbdev.

If the patch is changed to use the Kbuild file to pick the generic
variant of video.h then it is:

Reviewed-by: Sam Ravnborg <sam@ravnborg.org>

I also added an unrelated sparc comment, that can be addressed another
time.

arch/arc/include/asm/video.h only exists to pick
include/asm-generic/video.h.

The simpler way to do this is to add a line to:
arch/arc/include/asm/Kbuild:
+ generic-y += video.h

While touching the file I suggest to move to the simpler way using the
Kbuild file.

The same goes for all the other video.h files that only picks the
asm-generic variant.

video.c is always built-in, so the MODULE_ things can be dropped.
That is an unrelated clean-up so should not be part of this patch.

Does it need to be mandatory in include/asm-generic/Kbuild ?
