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.
