Subject: [PATCH v2 0/4] Add WoM feature as an IIO event
Date: Fri,  8 Mar 2024 15:10:19 +0000	[thread overview]
Message-ID: <20240308151023.379705-1-inv.git-commit@tdk.com> (raw)

From: Jean-Baptiste Maneyrol <jean-baptiste.maneyrol@tdk.com>

Add WoM (Wake-on-Motion) feature for all chips supporting it
(all except MPU-6000/6050/9150). WoM compares the magnitude of
the current accel sample with the previous one against a threshold
and returns an interrupt event if the value is higher.

WoM is checking against all axes and maps best to ROC since it
compares the last 2 samples. Thus report WoM as an accel
x|y|z roc_rising IIO event, add system wakeup functionality if
WoM is on and put the chip in low-power mode when the system
is suspended. Corresponding ROC value is in SI units since
the chip is using an absolute value in mg.

v2:
- Rework to use accel x|y|z roc for reporting WoM event
- Use only datasheet advertised bits for MPU-6500 family chips
