From 84c31a0466c12110af72d56c1dcc40759e848c55 Mon Sep 17 00:00:00 2001 From: Stephan Gerhold Date: Mon, 2 Aug 2021 17:56:54 +0200 Subject: dt-bindings: iio: accel: bma255: Add interrupt-names The binding already allows specifying both interrupt pins, but there is currently no way to describe a board where (for whatever reason) only INT2 is connected. Make it possible to use "interrupt-names" to make it explicit which interrupt pin is meant in the interrupts.
