dt-bindings: hwmon: (ina3221) Add ti,single-shot property (2e1ce201) · Commits · 戴 / test

By default, ina3221, as a hardware monitor, continuously measures the inputs and generates corresponding data. However, for battery powered devices, this mode might be power consuming. This patch adds a "ti,single-shot" property to allow changing the default continuous mode to single-shot operating mode. Signed-off-by:

		Optional properties:
		- ti,single-shot: This chip has two power modes: single-shot (chip takes one
		measurement and then shuts itself down) and continuous (
		chip takes continuous measurements). The continuous mode is
		more reliable and suitable for hardware monitor type device,
		but the single-shot mode is more power-friendly and useful
		for battery-powered device which cares power consumptions
		while still needs some measurements occasionally.
		If this property is present, the single-shot mode will be
		used, instead of the default continuous one for monitoring.
