[PATCH v3 0/9] drm: Add generic fbdev emulation

["Noralf Trønnes" <noralf@tronnes.org>]

This patchset adds generic fbdev emulation for drivers that supports GEM
based dumb buffers which support .gem_prime_vmap and gem_prime_mmap. An
API is begun to support in-kernel clients in general.

The only change this time is reworking client removal (again). Drop
reference counting, only allow the driver to remove a client.

Noralf.

Changes since version 2:
- Applied first 3 patches to drm-misc-next
- Drop client reference counting and only allow the driver to release
  clients.

Noralf Trønnes (9):
  drm: Begin an API for in-kernel clients
  drm/fb-helper: Add generic fbdev emulation .fb_probe function
  drm/pl111: Set .gem_prime_vmap and .gem_prime_mmap
  drm/cma-helper: Use the generic fbdev emulation
  drm/client: Add client callbacks
  drm/debugfs: Add internal client debugfs file
  drm/fb-helper: Finish the generic fbdev emulation
  drm/tinydrm: Use drm_fbdev_generic_setup()
  drm/cma-helper: Remove drm_fb_cma_fbdev_init_with_funcs()
