	Set the current counter value.

Detailed Description

Real-time clock control based on the MCUX IMX SNVS counter API.

The core Zephyr API to this device is as a counter.

Additional implementation details a user should take into account:

• an optional SRTC can be enabled (default) with configuration options
• the high power channel (id 0) is always available, the low power channel (id 1) is optional
• the low power alarm can be used to assert a wake-up
• the counter has a fixed 1Hz period

Function Documentation

mcux_snvs_rtc_set()

int mcux_snvs_rtc_set	(	const struct device *	dev,
		uint32_t	ticks
	)

Set the current counter value.

As the counter advances at 1Hz this will usually be set to the current UNIX time stamp.

Parameters

dev	the IMX SNVS RTC device pointer.
ticks	the new value of the internal counter

Return values

non-negative

on success
