[PATCH v4 0/5] Add driver for EC found on Qualcomm reference devices

[Anvesh Jain P]

From: Anvesh Jain P <anvesh.p@xxxxxxxxxxxxxxxx>

Add Embedded controller driver support for Hamoa/Purwa/Glymur Qualcomm
reference boards. It handles fan control, temperature sensors, access
to EC state changes and supports reporting suspend entry/exit to the EC.

---
Changes in v4:
  - Fix fan count calculation to use min() instead of max() to correctly
    cap fan_cnt at EC_MAX_FAN_CNT.
  - Remove unnecessary mutex lock/unlock.
  - Disable fan debug mode on ec module removal.
  - Fix issue reported by kernel test robot.
  - Consolidate hamoa-iot-evk specific changes into hamoa-iot-evk.dts.
  - Add board-specific compatible strings as per review comments.
  - Link to v3: https://lore.kernel.org/all/20260308233646.2318676-1-sibi.sankar@xxxxxxxxxxxxxxxx/

Changes in v3:
  - Revamp the bindings and driver to support generic ec specification
    that works across Qualcomm Hamoa/Purwa and Glymur reference devices.
  - Add ec nodes to Hamoa/Purwa CRDs and IOT-EVKs.
  - Add ec node to Glymur CRDs.
