From c80b4010d7e4a1ba2aa83928a659f4bd87c1019c Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 5 Nov 2015 10:18:14 +0100 Subject: [PATCH] ARM: ux500: Assign proper sensor IRQs for Snowball The Snowball gyro and magnetometer DRDY (data ready) lines are used as interrupt triggers by the IIO subsystem, triggering new data retrieveal on edges on this signal. Thus assign them as the primary interrupt in the device tree. The "other interrupt" coming out of the sensors is for alarms and similar complex events, the DRDY is for periodic measures, which is what we want. After this the generic_buffer tool from IIO tools gives a nice stream of readings after enabling the desired channels in sysfs.
