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.

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)

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
Written in collaboration with Quill Qi (Audio) <le.qi@oss.qualcomm.com>,
Jie Zhang (Graphics) <quic_jiezh@quicinc.com>, Shuai Zhang (Bluetooth)
<quic_shuaz@quicinc.com>, and Yongxing Mou (USB DisplayPorts)
<quic_yongmou@quicinc.com>.

Other platforms use a single line here. If you don't want to do it,
align data to start from the same column rather than restarting from the
column 1.

Okay, so how is WiFi controlled? Is there a GPIO? The DT should be
describing the hardware, not the UEFI behaviour.

Hi Dmitry, as I described in previous mail, On hamoa platfrom whole wifi module's power supply and enable gpio are voted in UEFI.
Hamoa is PC platform, so BIOS/UEFI behavior is compatible with Windows/ACPI architecture. UEFI is responsible for enabling power supply
for all devices which may be used in boot phase (such as WLAN may be used to boot from network).
So we need not Wifi chip's power and control GPIO in kernel side, thanks

This is not completely relevant. You are describing driver / Linux /
bootloader behaviour. I asked if there is a GPIO in the hardware. If
there is one, please add it here.

What if someone requests this GPIO from userspace and pulls it down?

Hi Dimitry,
During the UEFI boot phase, the WLAN enable GPIO has already been asserted, and the WLAN chip is functioning normally.
If we include this GPIO in the kernel device tree, when the kernel configures this GPIO, its voltage level may experience a brief glitch, which could cause the WLAN chip to reset and result in a PCIe link down.
So I didn't add wlan-en-gpio in this hamoa's device tree.

Here you are describing driver behaviour. It's a software issue and
can be handled in the driver.
I'm asking you to describe the hardware. From the hardware perspective
there is a GPIO pin. Please describe it in the DT.

The WCN pwrseq code handles this already, please simply describe the
hardware like the platform firmware description which you're creating
is supposed to
