Introduce support for the SolidRun i.MX8MP HummingBoard IIoT platform.
This board is a new design based on the i.MX8MP System on Module and
does not share much hardware with previous HummingBoard variants.
It comes with some common features:
- 3x USB-3.0 Type A connector
- 2x 1Gbps RJ45 Ethernet
- USB Type-C Console Port
- microSD connector
- RTC with backup battery
- RGB Status LED
- 1x M.2 M-Key connector with PCI-E Gen. 3 x1
- 1x M.2 B-Key connector with USB-2.0/3.0 + SIM card holder
- 1x LVDS Display Connector
- 1x DSI Display Connector
- GPIO header
- 2x RS232/RS485 ports (configurable)
- 2x CAN
In addition there is a board-to-board expansion connector to support
custom daughter boards with access to SPI, a range of GPIOs and -
notably - CAN and UART. Both 2x CAN and 2x UART can be muxed either
to this b2b connector, or a terminal block connector on the base board.
The routing choice for UART and CAN is expressed through gpio
mux-controllers in DT and can be changed by applying dtb overlays.

Move the USB controller configuration out of the i.MX8MM VAR-SOM dtsi
and into the VAR-SOM Symphony carrier board dts.
The SOM does not provide any USB connectors and carrier boards may
choose whether and how to route USB, therefore USB should be described
in the carrier-specific device tree instead of the SOM include.
While moving the nodes, align the Symphony USB description with the
carrier design by enabling both USB controllers, wiring USB1 to the
PTN5150 Type-C controller for dual-role operation, and updating the
PHY tuning and VBUS regulator pinctrl (including a sleep state).

The VAR-SOM-MX8MM currently integrates the NXP IW61x wireless module,
providing WiFi over SDIO and Bluetooth over UART.
Move the wireless module configuration out of the base
imx8mm-var-som.dtsi and provide dedicated variant includes.
The IW61x configuration is moved to imx8mm-var-som-wifi-bt-iw61x.dtsi
and used by the Symphony evaluation board device tree.
A separate imx8mm-var-som-wifi-brcm-legacy.dtsi include is added to keep
the configuration for the legacy Broadcom SDIO WiFi module used on
earlier SOM revisions.
To preserve compatibility with older SOM revisions, add a separate
imx8mm-var-som-symphony-legacy.dtb, which disables the IW61x setup and
applies the Broadcom-specific configuration.
The Broadcom-based SOM revision is no longer in production, but support
is kept for existing users.

Update the FEC Ethernet controller on the i.MX8MM VAR-SOM to match the
latest SOM hardware revision using the integrated MaxLinear MXL86110 PHY.
Add the PHY VDDIO supply regulator, adjust reset timings and add a
pinctrl sleep state for low-power operation.
The PHY LED signals originate on the SOM, but the actual LEDs are part
of the carrier implementation (RJ45 connector). Move the LED
configuration to the Symphony carrier device tree, matching the
evaluation board LED wiring.
Wake-on-LAN via magic packet is not supported at the VAR-SOM level and
is therefore not enabled in the SOM device tree nor in the official
evaluation carrier board configuration (symphony).
Designs requiring WoL support may enable it in their own carrier-specific
device trees if properly integrated at the hardware level.

The PMIC provides a level-shifter for the I2C lines to the RTC. As the
level shifter needs to be enabled before the RTC can be accessed, make sure
that the PMIC driver is probed first.
As the PMIC also provides the supply voltage for the RTC through the 3.3V
regulator, simply express this in the DT to create the required dependency.
Avoid sporadic boot hangs that occurred when the RTC was accessed before
the level-shifter was enabled.
