[PATCH 0/1] Add Toradex DSI to LVDS adapter with the 10.1" V2 display

[Leonardo Costa]

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

This patch adds the device tree overlay for the Toradex Capacitive Touch Display
10.1" LVDS V2 through the DSI to LVDS bridge on the Verdin iMX8M Mini.

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

- https://lore.kernel.org/linux-arm-kernel/20260623195741.495734-1-leoreis.costa@gmail.com/T/#t
    
    Adds the Toradex Capacitive Touch Display 10.1" LVDS V2 overlays for the
    Verdin AM62. This series is required because it adds the panel bindings for
    the display. It is currently in linux-next.

- https://lore.kernel.org/all/20260724-v1-verdin-imx8mm-dtbos-v2-0-9d7988bd76f6@toradex.com/T/#t

    Adds the other device tree overlays for the Verdin iMX8M Mini.

[PATCH 1/1] arm64: dts: freescale: imx8mm-verdin: 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
Verdin 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.
