# FP6 / inv_icm42600: force iio-sensor-proxy onto its POLL accel backend.
#
# inv_icm42600 registers no IIO trigger (software kfifo buffer pushed from the
# INT1 handler), but it does expose scan_elements/, so 80-iio-sensor-proxy.rules
# tags the accel with BOTH "iio-poll-accel" and "iio-buffer-accel".
# iio-sensor-proxy 3.9 tries iio-buffer-accel first, fails the trigger lookup
# ("Could not find trigger name associated with ...") and does NOT fall back to
# polling -- it registers the device anyway, so HasAccelerometer is true while
# sensor_device stays NULL. Every ClaimAccelerometer then hits
# "driver_set_polling: assertion sensor_device failed", AccelerometerOrientation
# is stuck at "undefined" and Plasma auto-rotate is dead.
#
# Glob the name: the DTS carries an icm42630/icm42631 compatible pair, so the
# IIO name follows whichever the fallback binds (see journal/imu/status.md).
