iio:proximity:sx9324: Add SX9324 support
Semtech SAR sensor SX9324 is an evolution of the SX9310:
It has 4 phases that can be configured to capture and process data
from any of 3 CS pins and provide independent detection:
proximity, table proximity or body proximity.
Gather antenna data:
echo sx9324-dev3 > trigger/current_trigger
echo 1 > scan_elements/in_proximity0_en
echo 1 > buffer/enable
od -v -An --endian=big -t d2 -w2 /dev/iio\:device3
(at 10Hz, the default).
Trigger events:
Setting:
thresh_falling_period: 2 (events)
thresh_rising_period: 2 (events)
in_proximity0_thresh_either_value: 300
in_proximity0_thresh_either_hysteresis: 72
using iio_event_monitor /dev/iio\:deviceX, approaching my hand to the
antenna pad, I see:
...
Event: time: 1634763907532035297, type: proximity, channel: 0, evtype:
thresh, direction: falling
Event: time: 1634763910138104640, type: proximity, channel: 0, evtype:
thresh, direction: rising
