From 6dc2c8711abcf87bb10039e99a0efb6f8b3a2cf9 Mon Sep 17 00:00:00 2001 From: Michael Srba Date: Wed, 23 Mar 2022 13:15:50 +0100 Subject: iio: imu: inv_mpu6050: Add support for ICM-20608-D The difference between the ICM-20608-D and the other ICM-20608 variants is the addition of a DMP (Digital Motion Processor) core. This difference is deemed substantial enough to change the WHOAMI register value. Since this driver doesn't currently acknowledge the exisence of something like a DMP core, simply copy ICM-20608 except for the aforementioned WHOAMI register.
