[PATCH v3 1/4] dt-bindings: arm: qcom: fix PURWA/HAMOA IOT SOM compatibles

[Yuanjie Yang]

The compatible strings for the Hamoa and Purwa IoT SOM platforms do not
match the naming used in the official hardware documentation.

The documentation identifies these SOMs using their IQ product names
rather than hamoa-iot-som or purwa-iot-som style names. In particular,
there are no SOM products documented with the names:

  - hamoa-iot-som
  - purwa-iot-som

Update the compatible strings to use the correct SOM names as described
in the hardware documentation:

  - hamoa-iot-som -> iq-x7181-evk-som
  - purwa-iot-som -> iq-x5121-evk-som

This aligns the DT compatible strings with the official product naming
and documentation.

These are already released, so marketing reasons are not enough to
change the ABI.

[PATCH v3 2/4] arm64: dts: qcom: fix PURWA/HAMOA IOT SOM compatibles

[Yuanjie Yang]

The compatible strings used for the Hamoa and Purwa IoT SOMs do not
match the naming used in the corresponding hardware documentation.

The SOMs are documented using their IQ product names and there are no
products identified as hamoa-iot-som or purwa-iot-som. Update the SOM
compatible strings to use the documented hardware names instead.

This keeps the DTS compatible strings aligned with the official
Qualcomm hardware documentation.

[PATCH v3 3/4] dt-bindings: arm: qcom: Add Advantech SOM-DB5830

[Yuanjie Yang]

Document the device tree binding for the Advantech SOM-DB5830 board based
on the Qualcomm X1E80100 SoC.

The platform consists of an Advantech SOM-6820 system-on-module (SoM)
mounted on an Advantech SOM-DB5830 carrier board. The SOM integrates an
IQ X7181 EVK SiP containing the Qualcomm X1E80100 SoC and its supporting
components.

[PATCH v3 4/4] arm64: dts: qcom: Add Advantech SOM-DB5830

[Yuanjie Yang]

Add the initial device tree for the Advantech SOM-DB5830 platform based on
the Qualcomm X1E80100 SoC.

The platform consists of an Advantech SOM-6820 system-on-module (SoM)
mounted on an Advantech SOM-DB5830 carrier board. The SOM integrates an
IQ X7181 EVK SiP containing the Qualcomm X1E80100 SoC and its supporting
components.

Compared to the HAMOA IOT EVK, PCIe controllers 3, 5 and 6 are routed to
expansion slots, while PCIe controller 4 is connected to an ASM1164
SATA controller. The platform does not provide a USB Type-C connector.
The eUSB repeater (TUSB2E111YCGR) is configured through hardware strapping
pins and therefore requires no software control.

The initial device tree includes support for:
- UART
- Regulators
- USB
- PCIe
- Pinctrl
- ADSP, CDSP
- UFS
- Graphics
- Video

Regulators, pinctrl, graphics, video, ADSP and CDSP support are
inherited from the common iq-x7181-evk-som.dtsi description.
