Subject: [PATCH v4 1/2] dt-bindings: hwmon: ti,ina2xx: Add ti,alert-polarity-active-high property
Date: Tue, 11 Jun 2024 11:36:25 +0200	[thread overview]
Message-ID: <20240611-apol-ina2xx-fix-v4-1-8df1d2282fc5@axis.com> (raw)
In-Reply-To: <20240611-apol-ina2xx-fix-v4-0-8df1d2282fc5@axis.com>

Add a property to the binding to configure the Alert Polarity.
Alert pin is asserted based on the value of Alert Polarity bit of
Mask/Enable register. It is by default 0 which means Alert pin is
configured to be active low open collector. Value of 1 maps to
Inverted (active high open collector).
