Describe the Cortex-M7 remote processor and its RPMsg memory regions for
Verdin iMX8M Plus, add shared OV5640 camera overlays for Verdin iMX8M
Mini and Verdin iMX8M Plus, and support a second camera through the
Verdin iMX8M Plus Mezzanine.

It applies on top of the recently submitted Verdin iMX8M Plus overlay
series:
https://lore.kernel.org/all/20260907-verdin-imx8mp-non-camera-overlays-ready-v1-0-ca0c63c2994f@toradex.com/

Add the Verdin board description and RPMsg reserved-memory regions,
following the Verdin iMX8M Mini description. A small overlay optionally
reserves Verdin UART_4 for Cortex-M7 firmware.

The camera patches are the follow-up promised when the OV5640 patches
were removed from v2 of the Verdin iMX8M Mini overlay series:
https://lore.kernel.org/r/20260713-v1-verdin-imx8mm-dtbos-v1-0-4acd63db4504@toradex.com

Verdin iMX8M Mini and Verdin iMX8M Plus can use the same 24-pin camera
connector on the Verdin Development Board, Dahlia and Mallow carrier
boards. The connector's sideband signals are routed to different GPIO
controllers, however, and the two SoCs use different capture pipelines.
Describing these details directly in an accessory overlay would require
a separate camera overlay for each SoM and carrier combination.

Following feedback on the Verdin iMX8M Mini series, introduce a binding
for the connector's sideband GPIO nexus. Add connector mappings to the
carrier descriptions and stable labels for the SoM-specific CSI media
nodes. This allows one pair of OV5640 overlays to be shared by both SoMs
and all three carrier boards.

The binding intentionally covers only the connector's GPIO signals.
MIPI CSI-2 endpoints, I2C, clocks and supplies continue to use their
existing bindings and are connected through stable labels in the Verdin
device trees.

The unsuffixed camera overlay describes the current camera module with
its 27 MHz oscillator. A separate overlay supports the legacy module
with its 24 MHz oscillator.

The Verdin iMX8M Plus Mezzanine exposes the SoC's second MIPI CSI-2
interface through another 24-pin camera connector. Its camera control
signals can be routed through either the default or alternate GPIO
jumper positions. Reuse the connector nexus for both configurations so
that they share one camera and media-pipeline description. Provide 27
MHz and 24 MHz variants for each jumper configuration.

The default GPIO routing is intended for a single camera because it
shares control signals with the native CSI_1 connector. The alternate
routing permits native and mezzanine cameras to be used together, but
conflicts with the Atmel MXT touchscreen GPIO.

The shared 27 MHz overlay was run-tested on Verdin iMX8M Mini and Verdin
iMX8M Plus. Both shared camera overlays were compiled, applied and
schema-validated with the WiFi and non-WiFi variants of all three
supported carrier boards on both SoCs. All mezzanine overlays were also
tested both standalone and in the dual camera use case on the iMX8MP.

When fw_devlink is enforcing probe ordering, camera probing depends on
the GPIO nexus support from [1]. Without it, fw_devlink can treat the
connector nexus itself as the supplier of the camera regulator instead
of following gpio-map to the underlying GPIO controller. This can leave
the regulator and camera waiting, for example:

  i2c 2-003c: deferred probe pending: i2c: supplier regulator-camera not ready

Changes in v2:
- dt-bindings: Drop the unrelated GPIO controller node from the example
- dt-bindings: Describe the physical connector (24-pin, 0.5 mm pitch
  FFC/FPC) shared by Toradex carrier boards, following the discussion
  on the compatible name
- Keep the toradex,camera-connector compatible, the all-ones
  gpio-map-mask and the absence of gpio-controller
- Rebase
- Link to v1: https://lore.kernel.org/r/20260910-verdin-imx8mp-hmp-camera-ready-v1-0-3c9349ecdb9f@toradex.com

Hi Frank,

Okay, I will send a separate series for this part with the needed edits.

Verdin UART_4 can be assigned to Cortex-M7 firmware. Add an overlay
that marks the UART as reserved so Linux does not claim the port.

The overlay is also combined with the Verdin iMX8M Plus Development
Board device tree to provide a ready-to-use DTB for the non-WiFi SoM
variant. UART_4 carries Bluetooth on WiFi SoMs.

I remember at another thread said, use imx-uart4-mcu.dtso for all uart4
case. It doesn't affect ov5460 part.

From: Ernest Van Hoecke <ernest.vanhoecke@toradex.com>

Toradex boards route the sideband signals of their 24-pin camera
connectors to different GPIO controllers. Camera overlays which name
those controllers directly must therefore be duplicated for each host
board.

Describe reset, power-down, detection and power-control as
connector-local GPIO functions. This lets an accessory overlay remain
independent of the host wiring. MIPI CSI-2, I2C, clocks and supplies
remain described separately because the GPIO nexus does not abstract
them.

This seems overly generic, but I assume that's what it's actually called
and if you make a new camera connector the name will be
"camera connector 2" or something.

These seem incredibly wide for something with only 4 gpios?

From: Ernest Van Hoecke <ernest.vanhoecke@toradex.com>

The Verdin Development Board, Dahlia and Mallow expose the same 24-pin CSI
camera connector, while Verdin iMX8M Mini and Verdin iMX8M Plus route its
sideband signals and media pipeline through different SoC resources.

Add a GPIO nexus to each carrier description and stable Verdin-level labels
for each module's CSI_1 I2C bus, receiver and capture engine. Keeping the
nexus in the carrier files avoids describing the physical connector on
carriers which do not provide it.

This gives accessory overlays a stable connector and media interface
without embedding either module's wiring in the accessory description.

From: Ernest Van Hoecke <ernest.vanhoecke@toradex.com>

The current and legacy Toradex OV5640 camera modules use the same connector
on Verdin iMX8M Mini and Verdin iMX8M Plus. Keeping SoC and carrier GPIO
references in the overlays would require a separate camera description for
every combination.

Use the connector nexus and stable CSI_1 media labels to describe the
camera once. Keep separate variants only for the current 27 MHz and legacy
24 MHz camera oscillators.

Build both DTBOs for installation and compose each with the two Verdin
Development Board DTBs to validate the module integrations.

From: Ernest Van Hoecke <ernest.vanhoecke@toradex.com>

The Verdin iMX8M Plus exposes its second MIPI CSI-2 interface through the
Verdin iMX8M Plus Mezzanine. Add overlays for using a Toradex OV5640 camera
on this interface.

The mezzanine can route the camera control signals through two jumper
configurations. Describe each configuration as a GPIO nexus mapping so the
camera description remains independent of the physical routing.

The default positions share the native CSI_1 GPIOs and are intended for a
single camera. The alternate positions permit simultaneous native and
mezzanine cameras, but conflict with the Atmel MXT touchscreen GPIO.

The current camera set uses a 27 MHz on-board oscillator. The legacy camera
module uses 24 MHz, so provide variants for both.
