Add OV5640 camera overlays for the Toradex SMARC iMX8MP SoM and its
development carrier board.

The overlays use the camera connector GPIO nexus, so this series
requires the toradex,camera-connector binding from v3 of the Verdin
iMX8M OV5640 series:
https://lore.kernel.org/r/20261022-verdin-imx8mp-hmp-camera-ready-v3-1-90a30b0b0d55@toradex.com

The camera regulator is supplied by the on-carrier 3.3 V rail, which is
described by the first patch.

Changes in v2:
- Include the on-carrier 3.3 V regulator patch, previously posted with
  the SMARC iMX8MP display overlays, which are deferred
- Refer to v3 of the toradex,camera-connector binding
- Rebase onto imx/dt64
- Link to v1: https://lore.kernel.org/r/20261002-v1-smarc-imx8mp-cameras-v1-0-a0e89182c625@toradex.com

Describe the fixed 3.3 V rail of the Toradex SMARC Development Board as
a regulator, like the existing on-carrier 1.8 V rail, so it can be
referenced as a supply by the devices it powers.

The SMARC Development Board exposes two 24-pin camera connectors with
reset and power-control signals routed through the SoM GPIO expander.

Describe the connectors as GPIO nexuses and add stable labels for the
camera buses and CSI receivers, so accessory overlays can use the
carrier's interfaces without embedding its GPIO routing.

commit d093f7d003a6a1108921f20ccc8a5a3a82a991c7
Author: Ernest Van Hoecke <ernest.vanhoecke@toradex.com>

arm64: dts: freescale: imx8mp-toradex-smarc: Add camera connector nexus

This commit adds two camera connector gpio nexus nodes to
imx8mp-toradex-smarc-dev.dts and adds labels for the camera i2c buses and
mipi csi receivers in imx8mp-toradex-smarc.dtsi.

[Severity: Medium]
Is there a devicetree binding schema documenting the
"toradex,camera-connector" compatible string used in camera-connector-0 and
camera-connector-1 in
arch/arm64/boot/dts/freescale/imx8mp-toradex-smarc-dev.dts?

Neither Documentation/devicetree/bindings/ in the tree nor this patch series
defines "toradex,camera-connector", which causes dtbs_check validation on
imx8mp-toradex-smarc-dev.dtb to fail to match any schema:

Documentation/devicetree/bindings/submitting-patches.rst:
  6) Any compatible strings used in a chip or board DTS file must be
     previously documented in the corresponding DT binding file
     in Documentation/devicetree/bindings.  This rule applies even if
     the Linux device driver does not yet match on the compatible
     string.

Should a binding schema be added before using this compatible string?

[Severity: High]
Will routing consumer gpios through camera-connector-0 and
camera-connector-1 cause fw_devlink to block consumer camera devices from
probing?

Because camera-connector-0 and camera-connector-1 are top-level nodes with a
compatible property, of_platform_default_populate_init() ->
of_platform_default_populate() -> of_platform_populate() ->
of_platform_bus_create() instantiates platform devices for them that have no
matching driver.

When a consumer device (such as camera@3c in the ov5640 overlay) references
&smarc_csi0 or &smarc_csi1 in reset-gpios and powerdown-gpios, fw_devlink
resolves the supplier through of_link_property() -> parse_gpios() ->
parse_suffix_prop_cells():

drivers/of/property.c:parse_suffix_prop_cells() {
	if (of_parse_phandle_with_args(np, prop_name, cells_name, index,
				       &sup_args))
		return NULL;

	return sup_args.np;
}

Unlike of_get_named_gpiod_flags() in drivers/gpio/gpiolib-of.c, which calls
of_parse_phandle_with_args_map() to traverse gpio-map,
parse_suffix_prop_cells() calls of_parse_phandle_with_args() and stops at
the nexus node itself.

As a result, fw_devlink_create_devlink() links the camera consumer to the
driverless camera-connector platform device instead of som_gpio_expander.
When the camera consumer probes via really_probe() ->
device_links_check_suppliers(), it sees that the supplier has no bound
driver:

drivers/base/core.c:device_links_check_suppliers() {
		if (link->status != DL_STATE_AVAILABLE &&
		    !device_link_test(link, DL_FLAG_SYNC_STATE_ONLY)) {
...
			device_links_missing_supplier(dev);
			ret = dev_err_probe(dev, -EPROBE_DEFER,
					    "supplier %s not ready\n", dev_name(link->supplier));
			break;
		}
}

Note that simply dropping the compatible property from camera-connector-0
and camera-connector-1 without updating fw_devlink to traverse gpio-map
would leave the nexus nodes without a struct device, causing
fwnode_links_check_suppliers() in device_links_check_suppliers() to defer
the consumer permanently with "wait for supplier /camera-connector-0" even
after driver_deferred_probe_timeout expires.

Could this regression be avoided by teaching fw_devlink to resolve through
gpio-map (for example using of_parse_phandle_with_args_map() in
drivers/of/property.c) before relying on a driverless gpio nexus node?

Add device tree overlays for the current 27 MHz and legacy 24 MHz
Toradex OV5640 camera modules connected to CSI0 and CSI1 on the SMARC
Development Board.

CAM_n_CON_PWRCTRL (pin 24) is an active-high power-up input of the
camera module, so it is described as an active-low powerdown GPIO.

The overlays are also combined with the SMARC Development Board device
tree to provide ready-to-use DTBs.
