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:

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.

Add support for MIPI DSI Host controller. Since MIPI DSI is not
available on stm32f746, the patch adds the "stm32f769.dtsi" file
containing the dsi node inside.

2.43.0
In the schematics of document UM2033, the power supply for the micro SD
card is the same 3v3 voltage that is used to power other devices on the
board. By generalizing the name of the voltage regulator, it can be
referenced by other nodes in the device tree without creating
misunderstandings.
This patch is preparatory for future developments.

As reported in the section 8.3 (i. e. Board revision history) of document
UM2033 (i. e. Discovery kit with STM32F769NI MCU) these are the changes
related to the board revision addressed by the patch:
- Board MB1166 revision A-09:
- LCD FRIDA FRD397B25009-D-CTK replaced by FRIDA FRD400B25025-A-CTK
The patch adds the DTS support for the new display which belongs to the
the Novatek NT35510-based panel family.
