This adds helpers for drivers that don't subclass drm_framebuffer and are backed by drm_gem_object(s). drm_fb_cma_helper is converted to use the helpers.
This patchset is part of a process to add a shmem gem library like the cma library. The common parts between the two goes into core or helpers.
Noralf.
Changes since version 2: - Expanded docs (Daniel) - Add drm_gem_fbdev_fb_create() instead of exporting drm_gem_fb_alloc(). This function is used by drivers/helpers to create a drm_framebuffer for use with fbdev emulation. - drm_gem_object_put_unlocked() is NULL tolerant (Joe Kniss) - Rebase tinydrm patch on new st7586 driver - Rebase arc and pl111 patches on 'drm: make drm_mode_config_func const'
Changes since version 1: - Pushed the new functions out to the cma drivers, so I could clean up the cma library.
