From 246d178c78685fc6ffcd8339ef0e64771024d82f Mon Sep 17 00:00:00 2001 From: Andrea Merello Date: Wed, 7 Sep 2022 15:21:56 +0200 Subject: iio: document pitch, yaw, roll modifiers Introduce ABI documentation for new modifiers used for reporting rotations expressed as euler angles (i.e. yaw, pitch, roll). It looks like we have some unit inconsistency along various IIO modifiers: it seems that incli is in deg, angl is in radians and rot isn't documented, but at least the adis16209 driver has rot in deg. Here we use deg (so angl is the only one using radians).
