Subject: [PATCH V3 0/5] Add driver for EC found on Qualcomm reference devices
Date: Mon, 9 Mar 2026 05:06:41 +0530 [thread overview]
Message-ID: <20260308233646.2318676-1-sibi.sankar@oss.qualcomm.com> (raw)
From: Sibi Sankar <quic_sibis@quicinc.com>
Add Embedded controller driver support for Hamoa/Purwa/Glymur Qualcomm
reference boards, which run on IT8987 and Nuvoton MCUs respectively. It
handles fan control, temperature sensors, access to EC state changes and
supports reporting suspend entry/exit to the EC.
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.
- Link to v2: https://lore.kernel.org/lkml/20241219200821.8328-1-maccraft123mc@gmail.com/
- Link to v1: https://lore.kernel.org/lkml/20240927185345.3680-1-maccraft123mc@gmail.com/
