[PATCH 0/5] ARM: dts: Add Colibri iMX6 overlays

[Antoine Gouby]

This series adds device tree overlays for the Colibri iMX6 SoM. The
overlays cover HDMI, VGA and parallel displays.

The series adds support for:

- HDMI Displays
- Toradex Capacitive and Resistive Touch 7" Parallel Displays
- VGA Displays

The Makefile entries build the standalone overlays as DTBOs, and add
ready-to-use composed DTBs for selected carrier boards and accessory
combinations, for build-time coverage.

[PATCH 1/5] ARM: dts: imx6dl-colibri: Add HDMI overlay

[Antoine Gouby]

From: Antoine Gouby <antoine.gouby@toradex.com>

Add a device tree overlay to enable the HDMI output on the Colibri iMX6.

The HDMI interface is not available on the Colibri SODIMM connector, it
is exposed through a dedicated 24-pin FFC connector on the module. The
FFC cable connects either directly to the Colibri Evaluation Board and
Iris carrier boards, which provide their own display output connectors,
or to the Colibri HDMI Adapter, which provides an HDMI connector and can
also be used with carrier boards without a dedicated display FFC
connector, such as Aster.

The overlay is also combined with the various versions of the Aster,
Evaluation Board v3, Iris and Iris v2 carrier board device trees,
including the Colibri iMX6 V1.2 variants, to provide ready-to-use DTBs.

[PATCH 2/5] ARM: dts: imx6dl-colibri: Add Toradex Capacitive Touch Display 7" Parallel

[Antoine Gouby]

From: Antoine Gouby <antoine.gouby@toradex.com>

Add a device tree overlay for the Capacitive Touch Display 7" Parallel
on the Colibri iMX6 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 touch interrupt and reset signals on SODIMM 107 and SODIMM 106 share
their pads with the WEIM nEXT_CS1 and nEXT_CS2 chip selects, disable
WEIM to avoid the pin conflict.

The overlay is also combined with the Colibri iMX6 V1.2 Iris v2 and
Aster carrier board device trees to provide ready-to-use DTBs.

[PATCH 5/5] ARM: dts: imx6dl-colibri: Add VGA overlay

[Antoine Gouby]

From: Antoine Gouby <antoine.gouby@toradex.com>

Add a device tree overlay for the VGA output on the Colibri iMX6
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 iMX6ULL and Colibri iMX7.

The overlay is also combined with the Colibri iMX6 V1.2 Aster,
Evaluation Board v3, Iris and Iris v2 carrier board device trees to
provide ready-to-use DTBs.

File name include key componets, lt161010

such as

imx6dl-colibri-7inch-lt161010.dtso, like others

	imx93-tqma9352-mba93xxla-lvds-tm070jvhg33.dtso

In case you will add more 7" panel in future, panel is quite easily EOL.

Let's try to settle this topic.

What you are proposing is not ok, I have already provided a complete
and detailed explanation on this topic here, please have a look again:

 - https://lore.kernel.org/all/20261005075319.GA7692@francesco-nb/
 - https://lore.kernel.org/all/20261005075319.GA7692@francesco-nb/

In addition to that, I'd like to say that this is exactly the same as
the raspberry pi display, see

 arch/arm64/boot/dts/ti/k3-am625-verdin-rpi-display-2-7in.dtso
 arch/arm64/boot/dts/renesas/r8a779g3-sparrow-hawk-rpi-display-2-5in.dtso
 arch/arm64/boot/dts/renesas/r8a779g3-sparrow-hawk-rpi-display-2-7in.dtso
 arch/arm64/boot/dts/renesas/r8a779g3-sparrow-hawk-rpi-display-2.dtsi


If you are concerned about this name being too generic and the risk of
name conflict or potential confusion my proposal is to add a `tdx`
prefix to the name.

The proposed name would be
`imx6dl-colibri-tdx-panel-cap-touch-7inch-parallel.dtso`. 

With such prefix we would have a clear Toradex "namespace" that would
prevent any kind of conflict and confusion.

Can we find a way forward on this, that allow both to have a correct
name and solve also your concerns?
