From f11e4374b44777aa2b51205999469a057f6f7faa Mon Sep 17 00:00:00 2001 From: Antoni Pokusinski Date: Thu, 2 Oct 2025 22:02:02 +0200 Subject: [PATCH] dt-bindings: iio: pressure: add binding for mpl3115 MPL3115 is an I2C pressure and temperature sensor. It features 2 interrupt lines which can be configured to indicate events such as data ready or pressure/temperature threshold reached.
