Subject: [PATCH v4 0/9] arm64: dts: freescale: Add support for the
 GOcontroll Moduline Display

Add inital support for 2 variants of the Moduline Display controller.
This system is powered by the Ka-Ro Electronics tx8p-ml81 COM, which
features an imx8mp SoC.

Signed-off-by: Maud Spierings <maudspierings@...ontroll.com>

Changes in v4:
- Add imx mailing list to ka-ro tx8p maintainer entry
- Fix several small indentation and ordering issues in devicetrees
- Change the two display adapter boards to overlays
- Add the missing patch for the Makefile to actually be able to build
  the new devicetrees
- Link to v3: https://lore.kernel.org/r/20250327-initial_display-v3-0-4e89ea1676ab@gocontroll.com

Changes in v3:
- Set regulator-boot-on and always-on on LDO5 of the pmic, after 20 ish
  seconds it auto disabled this LDO causing weird behaviour like
  ethernet droping out, wifi not working anymore. This LDO can control
  the IO voltage level of certain pins, just let it keep the u-boot
  value.
- Fix the comment style in imx8mp-pinfunc.h
- Rebase on newest next tag
- Link to v2: https://lore.kernel.org/r/20250226-initial_display-v2-0-23fafa130817@gocontroll.com

Changes in v2:
- Dropped the trivial-devices patch
- Added a patch with bindings for the gocontroll,moduline-module-slot
- Added a patch to spidev.c to enable the spidev driver for the module
  slot
- Added a missing usb-c connector in the av101hdt-a10 variant dts
- Switched to the new bindings for the module slots in the base dts
- Fixed some commit typos
- Link to v1: https://lore.kernel.org/r/20250224-initial_display-v1-0-5ccbbf613543@gocontroll.com
