Subject: [PATCH v4 1/2] dt-bindings: iio: imu: icm42600: add interrupt
 naming support

From: Jean-Baptiste Maneyrol <jean-baptiste.maneyrol@....com>

Add interrupt-names field for specifying interrupt pin configured.

Chips are supporting up to 2 interrupt pins with configurable interrupt
sources. Change interrupt to support 1 or 2 entries.
