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. [0]: https://lore.kernel.org/lkml/20220429084253.1085911-1-javierm@redhat.com/ 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.
