Subject: [PATCH v5 0/8] Add display support for stm32f769-disco board

The series adds display support for the stm32f769-disco board. It has been
tested on hardware revisions MB1225-B03 and MB1166-A09. This required
modifications to the nt35510 driver. As I do not have the Hydis HVA40WV1
display, it would be better if someone tested the driver in that
configuration.

Changes in v5:
- Add Acked-by tag of Krzysztof Kozlowski
- Add Reviewed-by tag of Linus Walleij
- Replace NT35510_ROTATE_180_SETTING with NT35510_ROTATE_0_SETTING
- Add Reviewed-by tag of Linus Walleij
- Tested-by tag of Linus Walleij
- Replace GPIOD_ASIS with GPIOD_OUT_HIGH in the call to devm_gpiod_get_optional().

Changes in v4:
- Put the "enum" list in alphabetical order

Changes in v3:
- Use "enum" to have less code changed

Changes in v2:
- Add Acked-by tag of Conor Dooley
- Add a dash in front of each "items:"
- Change the status of panel_backlight node to "disabled"
- Delete backlight property from panel0 node.
- Re-write the patch [7/8] "drm/panel: nt35510: refactor panel initialization"
  in the same style as the original driver in order to maintain the same
  structure.
- Re-write the patch [8/8] "drm/panel: nt35510: support FRIDA FRD400B25025-A-CTK"
  in the same style as the original driver.
