Subject: [PATCH v2 1/2] dt-bindings: hwmon: ti,ina2xx: Add ti,alert-polarity property
Date: Wed, 29 May 2024 11:47:44 +0200	[thread overview]
Message-ID: <20240529-apol-ina2xx-fix-v2-1-ee2d76142de2@axis.com> (raw)
In-Reply-To: <20240529-apol-ina2xx-fix-v2-0-ee2d76142de2@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).
