Subject: [RFC PATCH 0/3] io: imu: st_lsm6dsx: wake on acc event
Date: Fri, 14 Jun 2019 14:26:01 +0200
Message-ID: <20190614122604.52935-1-sean@geanix.com> (raw)

Hi,

The first patch enables the wake event creation in the suspend function,
it hardcodes the accelerometer to low power mode and the gyro is powered down.

The second and third patch is where I have some questions.
Is it okay to create an sysfs entry that can enable and disable the wake
events from the accelerometer?

The third patch is enabling us to set the threshold value.
Obviously this will need to be changed to represent a real value instead
of the raw register value.
Maybe I need to add a threshold avaliable sysfs entry?
Do I set it to a raw value calculated from the scale value or is some have
a better idea?

Finally is this the right approach to enable wake on accelerometer
events?
Please provide some idea's to how we could do it in the best and most
generic way.

/Sean
