Add device tree overlay to enable ICSSG0 dual EMAC support on AM642 EVM.
This overlay enables both ICSSG0 Ethernet interfaces (port0 and port1) in
dual EMAC mode.
Users can combine this with the existing ICSSG1 overlay to enable all four
ICSSG interfaces if needed.

Add support for the Toradex Aquila AM69 and its Development Carrier
Board.
The Aquila AM69 SoM is based on the TI AM69 SoC from the Jacinto 7
family and is designed for high-end embedded computing, featuring up to
32GB of LPDDR4 and 256GB eMMC storage, extensive multimedia support (3x
Quad CSI, 2x Quad DSI, DisplayPort, 5x Audio I2S/TDM), six Ethernet
interfaces (1x 1G, 4x 2.5G SGMII, 1x 10G), USB 3.2 Host/DRD support, and
a Wi-Fi 7/BT 5.3 module, alongside an RX8130 RTC, I2C EEPROM and
Temperature Sensor, and optional TPM 2.0 module.
Various nodes, inherited from the SoC dtsi, are explicitly disabled in
the SoM dtsi file (`status = disabled`) even if already disabled. These
nodes need to be disabled in the SoM, given that the node is not
complete there, explicitly disabling it limits the dependency on the SoC
dtsi allowing for refactoring without no impact on this file.

* x2 Gigabit Ethernet expansion connectors
* x4 3.5mm TRS Audio Jack Line In
* x4 3.5mm TRS Audio Jack Line Out
* x2 Audio expansion connectors
* x1 Type-A USB 2.0, x1 Type-C dual-role device (DRD) USB 2.0
* x1 UHS-1 capable micro SD card slot
* 32 GB eMMC Flash
* 512 Mb OSPI NOR flash
* x4 UARTs via USB 2.0-B
* XDS110 for onboard JTAG debug using USB
* Temperature sensors, user push buttons and LEDs
Although AM62D2 and AM62A7 differ in peripheral capabilities example
multimedia, VPAC, and display subsystems, the core architecture remains
same. To reduce duplication, AM62D support reuses the AM62A dtsi and the
necessary overrides will be handled in SOC specific dtsi file and a
board specific dts.

SolidRun HummingBoard-T has two options for M.2 connector, supporting
either PCI-E or USB-3.1 Gen 1 - depending on configuration of a mux
on the serdes lane.
The required configurations in device-tree were modeled as overlays.
The USB-3.1 overlay uses /delete-property/ to unset a boolean property
on the usb controller limiting it to USB-2.0 by default.
Overlays can not delete a property from the base dtb, therefore this
overlay is at this time useless.
Convert both overlays into full dts by including the base board dts.
While the pcie overlay was functional, both are converted for a
consistent user experience when selecting between the two mutually
exclusive configurations.

Add Toradex Verdin Ivy carrier board support. One notable feature of Ivy
is the analog inputs. These inputs are multiplexed, allowing the same
input to measure either voltage or current. For current measurements,
a GPIO switch enables or disables the shunt resistor. This process is
automatically managed by the Linux kernel using the IIO and MUX
subsystems. Voltage measurement is always enabled, but the voltage
measured by the ADC is scaled by a cascade voltage divider. In the
device tree, the equivalent gain of the voltage divider is used, which
can be calculated as follows:
------------

R1=30K | |

Vin = Analog Input (AIN)
Vout = ADC Input
Rth = Thevenin Equiv. Resistance
Vth = Thevenin Equiv. Voltage

R1 = 30K, R2 = 10K, R3 = 30K, R4 = 10K
RL = R4 = 10K
Rth = (R1 // R2) + R3 = 37500 Ohms
Vth = (Vin * R2) / (R1 + R2) = Vin/4;
Vout = (Vth * RL)/ (Rth + RL) = Vth/4.75 = Vin/19

P21 MCASP1_AFSX GPMC0_WAIT0
K17 MCASP1_ACLKX GPMC0_BE0N_CLE
K20 MCASP1_AXR2 GPMC0_ADVN_ALE
The factory default sets the pins for McASP1 use. (i.e.
Resistor Array RA1 installed, RA4 not installed).
For NAND use, RA1 has to be removed and RA4 must be
installed.

Add an overlay to change from the default OSPI NOR to QSPI NOR
for all am6xx-phycore-som boards.
The EEPROM on am6xx-phycore-soms contains information about the
configuration of the SOM. The standard configuration of the SOM
has an ospi nor, but if qspi nor is populated, the EEPROM will
indicate that change and we can use this overlay to cleanly change to
qspi nor.

The NAND expansion card plugs in over the HSE (High Speed Expansion)
connector. Add support for it.
We add the ranges property to the GPMC node instead of the NAND
overlay file to prevent below warnings.
/fragment@3/__overlay__: Relying on default #address-cells value
/fragment@3/__overlay__: Relying on default #size-cells value
As GPMC is dedicated for NAND use on this board, it should be OK.

J721E common processor board can be interfaced with the infotainment
expansion board[0] to enable the following audio/video interfaces in
addition to the peripherals provided by the common processor board:
- Two Audio codecs each with three Stereo Inputs and four Stereo Outputs
- Audio input over FPD Link III
- Digital Audio Interface TX/RX
- HDMI/FPD LINK III Display out
- LI/OV Camera input
Add support for TFP410 HDMI bridge located on the Infotainment Expansion
Board (connected to J46 & J51).
Add a HDMI connector node and connect the endpoints as below:
DSS => TFP410 bridge => HDMI connector
Also add the pinmux data and board muxes for DPI.
Rest of the peripherals are not added as of now.
