[PATCH v2 1/2] dt-bindings: embedded-controller: qcom,hamoa-crd-ec: Add Purwa IOT EVK

From: Anvesh Jain P

Date: Fri Jul 03 2026 - 06:01:39 EST


Document the qcom,purwa-iot-evk-ec compatible for the embedded controller
found on Purwa IOT EVK boards.

Like the CRD, the Purwa IOT EVK carries an on-board embedded controller,
provided by ITE and running on a separate MCU, which handles fan control,
temperature sensors and EC state-change/suspend notifications. The existing
Hamoa IOT EVK documents the same EC via qcom,hamoa-iot-evk-ec.

Like the other reference designs, it uses qcom,hamoa-crd-ec as its fallback
compatible.
