[PATCH v10 0/5] Add display support for stm32f769-disco board

[Dario Binacchi]

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 that have already been applied.

Changes in v10:
- Drop backlight. From a closer analysis of the schematics
  en.MB1225-F769I-B01_Schematic.pdf and en.mb1166-default-a09-schematic.pdf,
  it is noticed that the GPIO I14 is connected to an unmounted
  resistor (n/a), making the backlight functionality via GPIO unusable.
- Drop backlight references

Changes in v9:
- Drop 'interrupts' property to fix yaml checks
- Rename vcc_3v3 to to vcc-3v3
- Rename panel-dsi@0 to panel@0 to fix yaml warnings
- Change commit message
- Rename stm32f769-disco-mb1225-revb03-mb1166-reva09 to
  stm32f769-disco-mb1166-reva09

Changes in v8:
- Add Acked-by tag of Lee Jones
- Add Reviewed-by tag of Raphael Gallais-Pou
- Add Reviewed-by tag of Raphael Gallais-Pou
- Remove unit name from 'ltdc/port/endpoint@0' to fix the compiling
  warning:
  ../arch/arm/boot/dts/st/stm32f769-disco.dts:189.28-191.5: Warning
  (unit_address_vs_reg): /soc/display-controller@40016800/port/endpoint@0: node
  has a unit name, but no reg or ranges property
- Add Reviewed-by tag of Linus Walleij
- Add Reviewed-by tag of Raphael Gallais-Pou

Changes in v7:
- Replace .dts with .dtb in the Makefile

Changes in v6:
- Drop patches
  - [5/8] dt-bindings: nt35510: add compatible for FRIDA FRD400B25025-A-CTK
  - [7/8] drm/panel: nt35510: move hardwired parameters to configuration
  - [8/8] drm/panel: nt35510: support FRIDA FRD400B25025-A-CTK
  because applied by the maintainer Linus Walleij

Changes in v5:
- Replace GPIOD_ASIS with GPIOD_OUT_HIGH in the call to devm_gpiod_get_optional().

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