[PATCH v2] arm64: dts: ti: k3-am69-aquila: Add Toradex DSI to LVDS adapter with the 10.1" V2 display

[Leonardo Costa]

From: Leonardo Costa <leonardo.costa@toradex.com>

Add a device tree overlay for the Toradex DSI to LVDS Adapter with the
Toradex Capacitive Touch Display 10.1" LVDS V2. The adapter connects to the
Aquila DSI_1 interface. It is based on the Texas Instruments SN65DSI84
DSI-to-LVDS bridge and drives an Opto Logic SCX1001511GGC49 10.1" WXGA TFT
LCD LVDS panel. Touch input is provided by an ILITEK ILI251x capacitive
touch controller.

Changes in v2:
- Add comment explaining the panel timings difference between this
  overlay and the ones for the native LVDS interface (without the DSI to
  LVDS bridge).
- Add information in the hardware pin comments about which signals in
  the DSI to LVDS bridge each pin connects to.
- Add comment explaining why the rising edge is used on the TOUCH_INT#
  signal.
- Link to v1: https://lore.kernel.org/all/20260803173705.2268792-1-leoreis.costa@gmail.com/T/#

I have applied the following to branch ti-k3-dts-next on [1].
Thank you!

[1/1] arm64: dts: ti: k3-am69-aquila: Add Toradex DSI to LVDS adapter with the 10.1" V2 display
      commit: 0717c94b493171f350f113545f765cd3b71adc50

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.
