Hi,

if there are no further comments, can this series be merged through asm-generic?

Best regards

Make architecture helpers for display functionality depend on general
video functionality instead of fbdev. This avoids the dependency on
fbdev and makes the functionality available for non-fbdev code.

Patch 1 replaces the variety of Kconfig options that control the
Makefiles with CONFIG_VIDEO. More fine-grained control of the build
can then be done within each video/ directory; see parisc for an
example.

Patch 2 replaces fb_is_primary_device() with video_is_primary_device(),
which has no dependencies on fbdev. The implementation remains identical
on all affected platforms. There's one minor change in fbcon, which is
the only caller of fb_is_primary_device().

Patch 3 renames the source and header files from fbdev to video.

v3:
- arc, arm, arm64, sh, um: generate asm/video.h (Sam, Helge, Arnd)
- fix typos (Sam)
v2:
- improve cover letter
- rebase onto v6.9-rc1

Thomas Zimmermann (3):
   arch: Select fbdev helpers with CONFIG_VIDEO
   arch: Remove struct fb_info from video helpers
   arch: Rename fbdev header and source files
