[ Upstream commit dbeb8e72cc51536a70313e6d523dcb1429b40477 ] Rename display interface to match other modules to make it easier to use device tree overlays. The parallel RGB interface (lcdif) and all related stuff turn on in a device tree overlay. Keep them disabled in the main devicetree. As these subsystems are provided by module and not a part of boards, move their definitions into the module-level devicetree. Disable ad7879 touchscreen which turns on in a devic tree overlay. Remains it disabled in the main devicetree. Move Atmel MXT capacitive touch controller device tree nodes from carrier board to module level and add iomux pinctl groups for both the Capacitive Touch Adapter (using SODIMM 28/30) and the capacitive touch connector as found on later carrier boards (using SODIMM 106/107). Keep touchscreen and display nodes enabled for NAND based i.MX 7 modules, since device tree overlays are not yet supported. For the Colibri Evaluation Board keep the Capacitive Touch Adapter node disabled and PWM2, PWM3 enabled instead. For eMMC based modules keep nodes disabled to work in conjunction with device tree overlays. Add the iomuxc pinctrl group for the LVDS transceiver related signals to use it in a device tree overlay. While at it also alphabetically re=order them properties.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
