Subject: [PATCH v2 1/4] dt-bindings: arm: qcom: Document HAMOA-IOT-EVK
 board

Document the device tree binding for a new board named "EVK" based on
the Qualcomm Hamoa-IoT platform.

The "hamoa" name refers to a family of SoCs that share the same silicon
die but are offered in multiple speed bins. The specific SoC used in
this board is the x1e80100, which represents one such bin within the
Hamoa family.

Although "qcom,hamoa-iot-evk" is introduced as the board-specific
compatible, the fallback compatible remains "qcom,x1e80100" to preserve
compatibility with existing in-kernel drivers and software that already
depend on this identifier.
