Subject: [RESEND PATCH v2 0/6] Add display support on the stm32f746-disco board

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.

Dario Binacchi (6):
ARM: dts: stm32: add ltdc support on stm32f746 MCU
ARM: dts: stm32: add pin map for LTDC on stm32f7
ARM: dts: stm32: support display on stm32f746-disco board
dt-bindings: display: simple: add Rocktech RK043FN48H
drm/panel: simple: add support for Rocktech RK043FN48H panel
drm/stm: add an option to change FB bpp
