[PATCH v5 1/3] dt-bindings: adc-joystick: add poll-interval-ms

[Chris Morgan <macroalpha82@gmail.com>]

New devicetree attribute of "poll-interval-ms".

Add poll-interval support for the adc-joystick documentation. This is
an optional value and if not provided the adc-joystick works as it
does today (with triggered buffers). If this value is provided, the
adc-joystick driver is polled at the specified interval. A new
attribute was added instead of using the existing attribute of
"poll-interval" to comply with rules detailed in property-units.yaml.
