[PATCH v1 1/3] ARM: dts: imx7d-colibri-emmc: Add Toradex Capacitive Touch Display 7" Parallel

[Francesco Dolcini]

From: Francesco Dolcini <francesco.dolcini@toradex.com>

Add a device tree overlay for the Capacitive Touch Display 7" Parallel
on the Colibri iMX7 parallel RGB LCD interface.

The panel is a LogicTechno LT161010-2NHC 7" WVGA TFT Transmissive LCD
and the touch input is provided by an Atmel MaxTouch capacitive touch
controller.

The touch controller is connected to the Toradex 10-way Capacitive Touch
Interface connector available on Iris v2 and Aster carrier boards.

The overlay is also combined with the Iris v2 and Aster carrier board
device tree to provide a ready-to-use DTB.

[Severity: Medium]
Should the standalone overlay
imx7d-colibri-emmc-panel-cap-touch-7inch-parallel-touch-adapter.dtbo also be
added to this dtb-$(CONFIG_SOC_IMX7D) list?

Without it, the standalone overlay will not be copied to the deployment
directory when running make dtbs_install, unlike the sibling overlay
imx7d-colibri-emmc-panel-cap-touch-7inch-parallel.dtbo which is present
just below. This might break the ability for users to apply the overlay
dynamically via U-Boot on other carrier boards.

[Severity: Medium]
Should the standalone device tree overlay
imx7d-colibri-emmc-panel-res-touch-7inch-parallel.dtbo also be added to
the dtb-$(CONFIG_SOC_IMX7D) list here?

It looks like omitting it prevents it from being installed by
make dtbs_install, which might break the ability to dynamically load
the overlay from a bootloader on other compatible carrier boards.
