From: Martin Kelly Date: Fri, 20 Apr 2018 16:54:01 +0000 (-0700) Subject: dt-bindings: iio:imu:mpu6050: support more interrupt types X-Git-Tag: v4.19~841^2~225^2~50 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f3476e8f6230f5ffd8eebdd5fc0867ae53b75dcc;p=platform%2Fkernel%2Flinux-rpi.git dt-bindings: iio:imu:mpu6050: support more interrupt types Document that the hardware supports falling edge, rising edge, level low, and level high interrupt types, rather than just rising edge. The language used is the same as that in st_lsm6dsx.txt.
