Hi Jonathan

Thanks for review and comments.

When adding in_anglY_raw to in_angl_raw block, Should I update the KernelVersion form
4.17 to 5.12? Like blow:

What: /sys/bus/iio/devices/iio:deviceX/in_angl_raw
What: /sys/bus/iio/devices/iio:deviceX/in_anglY_raw
KernelVersion: 5.12
Contact: linux-iio@xxxxxxxxxxxxxxx
Description:
Angle of rotation. Units after application of scale and offset
are radians. Where present, Y indexes the channel.

Ok, Then I will keep the in_anglY_label block here. BTW, I didnot see in_voltageY_label
in sysfs-bus-iio in current kernel master branch.
