SubjectRe: IIO timestamp get skewed when suspending (st_lsm6dsx)
From
Date
Hi Thomas,

I have a question regarding CLOCK_REALTIME and CLOCK_BOOTTIME when
resuming from suspend.

We have run into problems with
drivers/iio/imu/st_lsm6dsx/st_lsm6dsx_core.c + the first patch from
Lorenzo Bianconi in this thread.
The accelerometer have an internal FIFO that includes a timestamp. When
we resume from suspend,
the driver resets the fifo ts counter and sets an internal reference to
that time.
But to me it looks like both CLOCK_REALTIME and CLOCK_BOOTIME aren't
ready when st_lsm6dsx_resume() is called.

If this is a limitation, can you point to other drivers that have been
able to workaround it?
Or can we wait for a flag or similar?

Best regards,
Sean Nyekjaer
