[PATCH v6 0/3] Initial support for Qualcomm Hamoa IOT EVK board

[PATCH v6 0/3] Initial support for Qualcomm Hamoa IOT EVK board

[Yijie Yang]

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

[PATCH v6 1/3] dt-bindings: arm: qcom: Document HAMOA-IOT-EVK board

[Yijie Yang]

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.

[PATCH v6 2/3] arm64: dts: qcom: Add HAMOA-IOT-SOM platform

[Yijie Yang]

The HAMOA-IOT-SOM is a compact computing module that integrates a System
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)

[PATCH v6 3/3] arm64: dts: qcom: Add base HAMOA-IOT-EVK board

[Yijie Yang]

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? If it supplies the panel, then the panel should be able to control
its power supplies.

No, it's not. It has PCIe4, but not a WiFi (which makes sense since WiFI
is not present on the SoM).

For Hamoa WiFi chip is powerd by UEFI not kernel, so WiFi can work without DTS node.

Only for usercase specific firmware requirement we need to add WiFi node.
For this case we need to wait both HSP and HMT's usercase specific firmwares are available on UPSTREAM, otherwise loading fw will fail.

So for now, we can skip adding the WiFi node. Once the use-case-specific firmware is ready in upstream, I can add the WiFi node separately for both HSP and HMT.
