[PATCH] arm64: dts: freescale: imx8mp-toradex-smarc: Add Toradex Capacitive Touch Display 10.1" LVDS V2

[Leonardo Costa]

From: Leonardo Costa <leonardo.costa@xxxxxxxxxxx>

Add a device tree overlay for the Toradex Capacitive Touch Display 10.1"
V2 on the Toradex SMARC Development Board LVDS0 interface. The panel is
an Opto Logic SCX1001511GGC49 10.1" WXGA TFT LCD and the touch input is
provided by an ILITEK ILI251x capacitive touch controller.

The overlay is also combined with the Toradex SMARC Development Board
device tree to provide a ready-to-use DTB.

This change depends on other patch series, and should be applied after
it:

- https://lore.kernel.org/all/20261002-smarc-imx8mp-display-submit-v1-0-f578c63fb676@xxxxxxxxxxx/T/#u

  Adds the other overlays for SMARC iMX8M Plus. This series is required
  because it adds the 3.3V power regulator used in the panel node. It's
  also needed for the patches to apply cleanly.
