Similar to feature present in older chip, it compares the magnitude of the last 2 accel samples against a threshold and returns an interrupt even if the value is higher. WoM maps best to accel x|y|z ROC event. This series add system wakeup functionality if WoM is on and wakeup is enabled when system suspends. This series also prepare the driver for supporting further APEX features like pedometer, tilt, ... It introduces an apex structure that will hold all APEX settings and track the enable state.
