Hello,
This series contain patches suggested by Thomas Zimmermann as a feedback for "[RFC PATCH v4 00/11] Fix some race between sysfb device registration and drivers probe" [0].
Since other changes in [0] were more controversial, I decided to just split this part in a new patch-set and revisit the rest of the patches later.
This is a v2 that addresses issues pointed out in v1.
Patch #1 is just a cleanup since when working on this noticed that some DRM drivers were passing as preferred bits per pixel to drm_fbdev_generic_setup() the value that is the default anyways.
Patch #2 renames the 'preferred_bpp' drm_fbdev_generic_setup() parameter to 'options', and make this a multi field parameter so that it can be extended later to pass other options as well.
Patch #3 finally adds the new DRM_FB_FW option and makes simpledrm to use it so that the registered framebuffer device is also marked as firmware provided.
The patches were tested on a rpi4 board with the vc4 DRM driver built as a module and either simplefb or simpledrm built-in.

Changes in v3: - Drop the preferred_bpp local variable (Laurent Pinchart). - Add a const qualifier to options parameter (Laurent Pinchart). - Drop the firmware local variable (Laurent Pinchart). - Use DRM_FB_OPTION() since DRM_FB_SET_OPTION() got renamed (kernel test robot).
Changes in v2: - Rename DRM_FB_SET_OPTION() to DRM_FB_OPTION() and make more clear in the kernel-doc what this macro does (Laurent Pinchart). - Fix some kernel-doc issues I didn't notice in v1. - Add Reviewed-by tags from Thomas and Laurent.
Javier Martinez Canillas (3): drm: Remove superfluous arg when calling to drm_fbdev_generic_setup() drm/fb-helper: Rename preferred_bpp drm_fbdev_generic_setup() parameter drm: Allow simpledrm to setup its emulated FB as firmware provided
