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/#
