The series adds support for the display on the stm32f746-disco board,
along with a generic patch that adds the "bpp" parameter to the stm-drm
module. The intention is to allow users to size, within certain limits,
the memory footprint required by the framebuffer.
Changes in v2:
- Add 'Acked-by' tag of Conor Dooley.
- Fix build warning reported by kernel test robot.
- Add 'Reported-by' tag of kernel test robot.

Boards that use the STM32F{4,7} series have limited amounts of RAM. The
added parameter allows users to size, within certain limits, the memory
footprint required by the framebuffer.

Hi Dario,
Thanks for this serie. I'll look at it shortly.
In the meantime, would it be possible to send it again as I think it is not
complete.
patchwork and lore.kernel.org both prompt incomplete parts of your serie.
