Introduce the device tree, DT bindings, and driver modifications required
to bring up the HAMOA-IOT-EVK evaluation board—based on the X1E80100 SoC—to
a UART shell.
This patch set focuses on two key hardware components: the HAMOA-IOT-SOM
and the HAMOA-IOT-EVK carrier board.
The HAMOA-IOT-SOM is a compact System on Module that integrates the SoC,
GPIOs, and PMICs. It is designed to be modular and can be paired with
various carrier boards to support different use cases.
The HAMOA-IOT-EVK is one such carrier board, designed for IoT scenarios.
It provides essential peripherals such as UART, on-board PMICs, and
USB-related components.
Together, these components form a flexible and scalable platform, and this
patch set enables their initial bring-up through proper device tree
configuration and driver support.
Qualcomm SoCs often have multiple product variants, each identified by a
different SoC ID. For instance, the x1e80100 SoC has closely related
variants such as x1e78100 and x1e001de. This diversity in SoC identifiers
can lead to confusion and unnecessary maintenance complexity in the device
tree and related subsystems.
To address this, code names offer a more consistent and project-agnostic
way to represent SoC families. They tend to remain stable across
development efforts.
This patch series introduces "hamoa" as the codename for the x1e80100 SoC.
Going forward, all x1e80100-related variants—including x1e81000 and others
in the same family—will be represented under the "hamoa" designation in the
device tree.
This improves readability, streamlines future maintenance, and aligns with
common naming practices across Qualcomm-based platforms.
Features added and enabled:
- UART
- On-board regulators
- Regulators on the SOM
- PMIC GLINK
- USB0 through USB6 and their PHYs
- Embedded USB (eUSB) repeaters
- USB Type-C mux
- PCIe6a and its PHY
- PCIe4 and its PHY
- Reserved memory regions
- Pinctrl
- NVMe
- ADSP, CDSP
- WLAN, Bluetooth (M.2 interface)
- USB DisplayPort
- Graphic
- Audio

Document the device tree binding for the HAMOA-IOT-EVK board, which uses
the Qualcomm X1E80100 SoC.
The EVK consists of a carrier board and a modular System-on-Module (SoM).
The SoM integrates the SoC, PMICs, and essential GPIOs, while the EVK
carrier board provides additional peripherals such as UART and USB
interfaces.

on Chip (SoC) — specifically the x1e80100 — along with essential
components optimized for IoT applications. It is designed to be mounted on
carrier boards, enabling the development of complete embedded systems.
This change enables the following components:
- Regulators on the SOM
- Reserved memory regions
- PCIe6a and its PHY
- PCIe4 and its PHY
- USB0 through USB6 and their PHYs
- ADSP, CDSP
- WLAN, Bluetooth (M.2 interface)

The HAMOA-IOT-EVK is an evaluation platform for IoT products, composed of
the Hamoa IoT SoM and a carrier board. Together, they form a complete
embedded system capable of booting to UART.
This change enables the following peripherals on the carrier board:
- UART
- On-board regulators
- USB Type-C mux
- Pinctrl
- Embedded USB (EUSB) repeaters
- NVMe
- pmic-glink
- USB DisplayPorts
- Bluetooth
- Graphic
- Audio

Why do we have DSPs in the SoM, while GPU is enabled only in the board

My bot found new DTB warnings on the .dts files added or changed in this
series.
Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.
If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:
pip3 install dtschema --upgrade
This patch series was applied (using b4) to base:
Base: using specified base-commit b899981540841e409e496083921f2e5c4c209925
If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)

Huh, why bothering with testing prior to sending to mailing list if
