From 02104141f3fa08c0b8d3924e0db4744212ed5b9a Mon Sep 17 00:00:00 2001 From: Stephan Gerhold Date: Mon, 2 Aug 2021 17:56:55 +0200 Subject: [PATCH] dt-bindings: iio: accel: bma255: Add bosch,bmc156_accel BMC156 is very smilar to BMC150, but it has only one accelerometer interrupt pin. It would make sense if only INT1 was exposed but someone at Bosch decided to only have an INT2 pin. In this case, it does not make sense if the first interrupt pin is treated as INT1 (since that pin does not exist). Add a note to the bindings that the first interrupt pin is treated as INT2 for BMC156.
