Add support for Qualcomm's Monaco-ac-sku Evaluation Kit (EVK) without
safety monitoring feature of Safety Island(SAIL) subsystem.
This board is based on Qualcomm's QCS8300-AC variant SoC.
Monaco-ac-sku EVK board is a single board computer (SBC) that supports various
industrial applications, including factory automation, industrial
robots, drones, edge AI boxes, machine vision, autonomous mobile
robots (AMRs), and industrial gateways.

Add initial device tree support for monaco-ac EVK board,
based on Qualcomm's monaco-ac (QCS8300-AC) variant SoC.
monaco-ac EVK is single board supporting these peripherals :
- Storage: 1 × 128 GB UFS, micro-SD card, EEPROMs for MACs,
and eMMC.
- Audio/Video, Camera & Display ports.
- Connectivity: RJ45 2.5GbE, WLAN/Bluetooth, CAN/CAN-FD.
- PCIe ports.
- USB & UART ports.
Compared to "monaco-evk" variant, which utilizes higher tier QCS8300-AA
SKU (supporting 40 TOPS of NPU) and a 4-PMIC (2x PM8650AU + Maxim MAX20018
+ TI TPS6594) power delivery network (PDN) to support higher power
requirement. This board utilizes lower tier QCS8300-AC SKU
(Supporting 20 TOPS of NPU) and a simplified 2 PMIC(2x PM8650AU) PDN.
Add support for the following components :
- GPI (Generic Peripheral Interface) and QUPv3-0/1
controllers to facilitate DMA and peripheral communication.
- TCA9534 I/O expander via I2C to provide 8 additional GPIO
lines for extended I/O functionality.
- USB1 controller routed to a TypeC connector in device mode to
support USB peripheral operations.
- Remoteproc subsystems for supported DSPs such as Audio DSP,
Compute DSP and Generic DSP, along with their corresponding
firmware.
- Configure nvmem-layout on the I2C EEPROM to store data for Ethernet
and other consumers.
- QCA8081 2.5G Ethernet PHY on port-0 and expose the
Ethernet MAC address via nvmem for network configuration.
It depends on CONFIG_QCA808X_PHY to use QCA8081 PHY.
- Support for the Iris video decoder, including the required
firmware, to enable video decoding capabilities.
- PCIe0 and PCIe1 controller and phy-nodes.
- Sound card and max98357a based I2S speaker amplifier.

If it is a different SoC SKU, should it be reflected in the SoC compat
strings?

Monaco‑AC does not introduce any S/W differences compared to Monaco SoC
-- All IP blocks and bindings remain identical from S/W PoV, Hence
haven't included the SoC SKU in the SoC compat strings.
Hope this is okay ? Your view on this ?

You are descibing -AC as the main difference between the kits, but then
you say that -AC doesn't bring new software interfaces. What is the
difference then between monako-evk and the -ac variant?
Also, from the naming point of view, it is monako-ac-evk, not the other
way.

The major difference between monaco-evk and monaco-ac-evk boards is that
of power grid. monaco-evk requires 4 PMICs (2x PM8650AU + Maxim MAX20018
+ TI TPS6594) to support higher power requirements of monaco-AA variant
of SoC which supports upto 40 TOPS of NPU - whereas this board
"monaco-ac-evk" supports 20 TOPS of NPU and has lesser power
requirements hence 2 PMICs suffice the power requirements (2x PM8650AU).

Ack, will change this to "monaco-ac-evk" in the next version.
Also, should I change DT name "monaco-ac-sku.dts" instead of current
"monaco-evk-ac-sku" ?

Corrected Typo - I meant change DT name to "monaco-ac-evk.dts" and drop
"sku" from the DT name as well ?

Is that the only difference? Is the PCB the same? Should we have a
single common file for those two variants?

monako-ac-evk.dtsi.

Yes, the major differences b/w 2 boards are:
1. Monaco-AA version of SoC in monaco-evk v/s Monaco-AC version of SoC
in monaco-ac-evk board.
2. 4 PMICs (2x PM8650AU + Maxim MAX20018 + TI TPS6594) in monaco-evk
board v/s 2 PMICs (2x PM8650AU) in monaco-ac-evk board.
PCB is different for both of the boards.
Can I restructure as below to avoid code duplication ?
"monaco-evk-common.dtsi" --> This will add/enable all the common
peripherals of monaco-evk and monaco-ac-evk.
monaco-evk.dts --> Include "monaco-evk-common.dtsi" and enable
monaco-evk specific changes.
monaco-ac-evk.dts --> Include "monaco-evk-common.dtsi" and enable
monaco-ac specific changes
Does the above file re-structuring looks good ?
