[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.

[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 Capacitive Touch
Adapter, the connection to the various carrier boards is documented in
the datasheet [1].

The overlay is also combined with the Eval carrier board device tree to
provide a ready-to-use DTB.

I already sent out pull request for 7.3.  It will be for next version 7.4

I doesn't plan put it into linux-next until 7.3-rc1. It keeps continue
development during merge windows. I hope this ways to improve overall
efficiency.
