[riot-users] Cortex Kinetis KW2xD Low Power Modes

I'm using RIOT with KW2xD Kinetis MCU for Wireless sensors.

I could observe that the board's current is 10mA when idle which is too
high for long battery

The application note :
says there are Very Low Power Run / Wait / Stop modes.

There are at lease these functions to integrate in RIOT Kernel.

void enter_vlpr(void); => Enter low power run mode
void exit_vlpr(void);  => Go back in regular power run mode
void enter_vlps(void); => Go to low power sleep

What is the correct way to integrate this low power mode in Riot Power
Are there existing implementation for these low power modes for other MCUs
to take in example ?
