From 4df685091dfe27ff557031f8429906fb5d8240ea Mon Sep 17 00:00:00 2001 From: Stephan Gerhold Date: Wed, 2 Dec 2020 11:46:56 +0100 Subject: iio: imu: inv_mpu6050: Add support for MPU-6880 MPU-6880 seems to be very similar to MPU-6500 and it works fine with some minor additions for the mpu6050 driver. Add the necessary defines for it and make it use the same registers as MPU-6500 but with a FIFO size of 4096.
