Subject: [PATCH v2 1/4] hwmon: (pmbus/core) increase number of phases and add new mask
Date: Fri, 11 Sep 2026 14:53:37 +0100 [thread overview]
Message-ID: <20260911-hwmon-max20826-support-v2-1-5e30cbd97d84@analog.com> (raw)
In-Reply-To: <20260911-hwmon-max20826-support-v2-0-5e30cbd97d84@analog.com>
Increase the number of phases to 16 as a new upcoming device supports
such a number.
While at it, add a new mask for controlling the source of the output
voltage.
