Add device tree overlays for the Toradex display accessories on the
Colibri iMX6ULL eMMC parallel RGB LCD interface, mirroring what was
recently merged for the Colibri iMX7 eMMC:

 - Capacitive Touch Display 7" Parallel, touch on the 10-way Capacitive
   Touch Interface connector (Iris v2, Aster)
 - Capacitive Touch Display 7" Parallel, touch through the Capacitive
   Touch Adapter (Eval v3)
 - Resistive Touch Display 7" Parallel (Eval v3)
 - VGA output through a non-programmable video DAC (Aster, Eval v3,
   Iris, Iris v2)

The panel, backlight and LCDIF part of each overlay is identical between
the two modules, both using the same LCDIF binding and labels. Instead
of duplicating it, each patch moves that part out of the corresponding
Colibri iMX7 eMMC overlay into a dtsi shared by the two modules and
includes it from both. Only the Atmel MaxTouch wiring, the conflicting
PWM channels and the BL_ON pinctrl and GPIO driving the VGA DAC power-save
input stay in the SoC specific overlays. The shared files follow the
imx6ul-imx6ull-*.dtsi naming already used in the same directory.

The first three patches are fixes needed before the rework. Patch 1
(from Emanuele) drives the VGA DAC power-save input through the BL_ON
signal, without it the Eval and Aster carrier boards show a black image.
Patch 2 adds the Colibri iMX7 eMMC touch adapter and resistive touch
.dtbo to dtb-y, as they were built only as a dependency of the combined
DTBs and never shipped by dtbs_install. Patch 3 aligns the Colibri
iMX6ULL backlight brightness levels with the Colibri iMX7 ones, the LED
driver of the 7" displays turns off below roughly 15% duty cycle and only
the three highest of the current levels produced a visible image.

From: Emanuele Ghidoli <emanuele.ghidoli@toradex.com>

On the Colibri Evaluation Board and Aster carrier board, the BL_ON signal
on SODIMM 71 controls the active-low power-save input of the ADV7125 VGA
DAC. The VGA overlay does not drive this signal, leaving the DAC disabled.
The monitor receives the sync signals but displays a black image.
On the Iris carrier board, the DAC power-save input is pulled high
so the missing GPIO configuration does not prevent the VGA output from
working.

Add the pinctrl configuration and an active-high enable GPIO to the VGA
bridge so that the simple-bridge driver takes the DAC out of power-save
when enabling the output.

The Capacitive Touch Display 7" Parallel with Touch Adapter and the
Resistive Touch Display 7" Parallel overlays are only built as a
dependency of the combined Eval carrier board DTBs and are not listed in
dtb-y, so the standalone .dtbo files are not installed by dtbs_install.

Add them to dtb-y like the other Colibri iMX7 eMMC overlays.

The LED driver of the Toradex 7" parallel displays turns the backlight
off below roughly 15% PWM duty cycle, with the current brightness levels
only the three highest ones produce a visible image.

Use the same brightness levels as on the Colibri iMX7, which is used with
the same displays, keeping the default brightness at about the same
value.

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

Add a device tree overlay for the Capacitive Touch Display 7" Parallel
on the Colibri iMX6ULL eMMC 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 panel, backlight and LCDIF configuration is identical to the Colibri
iMX7 eMMC one, only the Atmel MaxTouch controller wiring is SoC
specific. To avoid duplicating it, rework the Colibri iMX7 eMMC overlay
moving the common part to a new dtsi shared between the two modules,
and include it from both overlays.

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

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

Add a device tree overlay for the Capacitive Touch Display 7" Parallel
on the Colibri iMX6ULL eMMC 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 panel, backlight and LCDIF configuration is identical to the Colibri
iMX7 eMMC one, only the Atmel MaxTouch controller wiring and the
conflicting PWM channels are SoC specific. To avoid duplicating it,
rework the Colibri iMX7 eMMC overlay to include the dtsi shared between
the two modules, and use it from the new overlay as well.

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

Add a device tree overlay for the Resistive Touch Display 7" Parallel
on the Colibri iMX6ULL eMMC parallel RGB LCD interface.

The panel is a LogicTechno LT161010-2NHR 7" WVGA TFT Transmissive LCD
with a resistive touch.

The overlay content is identical to the Colibri iMX7 eMMC one. To
avoid duplicating it, rework the Colibri iMX7 eMMC overlay moving its
content to a new dtsi shared between the two modules, and include it
from both overlays.

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

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

Add a device tree overlay for the VGA output on the Colibri iMX6ULL eMMC
parallel RGB LCD interface. The VGA output is driven through a
non-programmable video DAC without VESA DDC I2C signals to a DVI
connector. The DAC power-save input is driven by the BL_ON signal on
SODIMM 71, like on the Colibri iMX7.

The overlay content is identical to the Colibri iMX7 eMMC one, only the
GPIO driving the DAC power-save input is SoC specific. To avoid
duplicating it, rework the Colibri iMX7 eMMC overlay moving the common
part to a new dtsi shared between the two modules, and include it from
both overlays.

The overlay is also combined with the Aster, Evaluation Board v3, Iris
and Iris v2 carrier board device trees to provide ready-to-use DTBs.
