Turn off TWI and GPIO

[plotkin1996]

Hi,

How do I configure Zephyr to turn off TWI and GPIO while in sleep mode? Once I enable those, idle power consumption doubles. I tried using device_pm_enable() on initialization, and then device_pm_get_sync() and device_pm_put() every time i use them, but it made the program reset on start, so it's obviously not the right way to do it.

Never mind, it did turn off automatically, but my interval between TWI usage events was too small (5 seconds) and it looks like Zephyr doesn't enter full power save if a timer event is expected so soon. Increasing the interval brought consumption down right after the timer event.
