[PATCH v2 0/14] drm: minimize drmP.h dependencies

[PATCH v2 0/14] drm: minimize drmP.h dependencies

[Sam Ravnborg]

The goal with this small series is to remove the last bits
that prevents us from removing drmP.h driver-by-driver or file by file.

- drmP.h is now stripped down to include files and forward declarations.
- All header files in include/drm/ no longer include drmP.h.

The series was made on top of drm-misc-next
Build tested using arm and x86 all{yes,mod}config

The patches are trivial but touches a lot of files,
so a lot of people on cc: for the individual patches.

I expect the full series to be applied to drm-misc-next

There are still ~700 uses of drmP.h so a long way ahead of
us to get rid of it.
(The last mail said 900 but that was a typo)

The kernel-doc parts that I authored in the following
may require some extra info as I know too little about
DRM to be able to write something really useful.
Or at least review by someone with knowledge of DRM,
but that goes for everything.

v2:
- DRM_SWITCH_POWER as enum (Daniel Vetter)
- Prefer forward decalration over includes (Laurent Pinchart)
- Updated drm_device to use kerneldoc style (Daniel Vetter)
- Improved commit messages (David Lechner)
- Split up patch when removing drmP.h from drm_gem_cma_helper.h
- rebased on top of drm-misc-next
- dropped patch already applied
- added reviewed-by from Laurent Pinchart (Laurent Pinchart)
- add drm_framebuffer.h patch
- add kernel-doc comments to drm_util.h
- moved EXPORT_SYMBOL_FOR_TESTS_ONLY to drm_util.h
- added note to drmP.h not to add new stuff and not to use in new files

The series should have been a reply to this cover letter,
but my tooling lost me - sorry!

Hi Sam,

And the $subjects that say "reply" should say "rely" I think.

Yep, fixed. Will be part of v3.

Thanks,
