Add device tree overlays compatible with upstream kernel.
Display-related overlays are excluded due to missing display subsystem
(DSS) support in the upstream kernel.

The base device tree droped the gpio-hog on the LVDS_DSI_SEL line
relying on the pulldown resistor enabled for the pin.
Remove setting a property in the no longer existing gpio-hog.
The base device tree already sets the mux correctly for DSI.

Since commit ff06ea04e4cf ("clk: imx: clk-imx8mp: Allow media_disp pixel
clock reconfigure parent rate") from Linux kernel, it is possible to set
the clock rates inside &lvds_bridge node, instead of overwriting the
ones from &media_blk_ctrl.
When the overlay was first added, we did not realize this, therefore
update the overlay by dropping the unneeded assigned-clock-rates
in &media_blk_ctrl.

Currently this display is not working because is it using the wrong

The Toradex Arducam OV5640 module uses a 27MHz on-board crystal
oscillator for its camera clock, while the current overlays assume the
camera clock is 24MHz. This creates a 10% clock discrepancy for the
module, affecting camera frame rate. Add dedicated overlays to support
the Arducam OV5640.
Worth mentioning that this patch also removes support for legacy OV5640
modules that depends on the SoC for camera clock generation. In other
words, legacy modules without a built-in oscillator will no longer
function.

The apalis-imx6_panel-edt-5.7inch_overlay.dts and
apalis-imx6_panel-edt-7inch_overlay.dts overlays still include the,
already removed, "apalis-imx6_stmpe-ts_overlay.dtsi". Therefore, they

need to selectively do so in an overlay, remove the forgotten include.

The Apalis and Colibri iMX6 v1.2 replaced the STMPE811 which is now EOL
with the AD7879 touch controller and TLA2024 ADC.
Both the AD7879 and the STMPE811 are now enabled by default in the
device trees. There is no need to selectively enable them in an overlay.
Therefore, delete and no longer include the STMPE overlay DTSIs:

Revise DSI overlay not relying anymore on the panel-lvds, on the
touch-controller or any such DT node being available in the base DT,
those nodes are not supposed to be there and were partially removed with
https://lore.kernel.org/all/20250214092634.12414-1-francesco@dolcini.it/.
This change redefine all the required node in the overlay DT files, so
it would work whatever is available in the SOM/carrier DT, to be safe
it forces `status = "okay"` that might be needed if a previous node
was defined as disabled in the base DT file.
The display link nodes and the backlight are also renamed to have a
unique name, ensuring that no node name or label clash happen when
multiple overlay files are applied at the same time.
lt17041 display dtsi was modified by some file including it, it is now
split in 2 files trying to minimize confusion on the actual timings
that are used.

Adapt the OV5640 overlay to support the Toradex Arducam OV5640 module.
The key difference from the current Toradex camera module is that
Arducam requires the POWER_EN signal from the Toradex CSI camera
interface to be set to HIGH to enable the camera power supply. In the
Toradex module, this is managed by a pull-up resistor on the camera
hardware, so no software changes are necessary.
It's also worth noting that in the device tree overlay, there is no
pinctrl on the regulator node because the GPIO for power enable is
already configured in the SOC pinctrl/GPIO controller nodes in the
Toradex device tree for the SOM/Carrier Boards.

The touch controller generates a negative pulse of ~ 200us lenght.
The falling edge is a bit slower and noisier due to the used level
translation in HW. Change to trigger the interrupt on the rising edge
to lower the possibilty of triggering two interrupts due to noise.
