Subject: [PATCH v6 2/2] dt-bindings: hwmon: Add sample averaging properties for ADM1275
Date: Wed,  2 Mar 2022 20:38:17 +0800	[thread overview]
Message-ID: <20220302123817.27025-3-potin.lai@quantatw.com> (raw)
In-Reply-To: <20220302123817.27025-1-potin.lai@quantatw.com>

Add documentation of new properties for sample averaging in PMON_CONFIG
register.

New properties:
- adi,volt-curr-sample-average
- adi,power-sample-average
