From 3cc17e61d4dd9594fc6a2d15d88bb91f4bc61e75 Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Sun, 26 Mar 2017 12:10:59 +0100 Subject: [PATCH] iio:imu:mpu6050 update i2c bindings to reflect i2c-gate and supported parts These bindings are somewhat lagging the state of the driver. The i2c-gate bindings are documented elsewhere, but it seems sensible to at least have an example and cross reference in here. SPI bindings will need to be the subject of a future patch.
