devices power management from Linux

[angelo_d]

Hi all,

i am in a custom imx6q solution, was looking for some documentation on how to manage devices correctly from Linux, when their power is controlled (enabled/disabled) by gpio.

I suspect that doing this manually, externally from drivers (like by sysfs) could result in driver management issues after power up.

I tried also using gpio regulators but they don't seem to work as expected.

What should be the proper way to go ?

Thanks,

angelo

Hi Angelo

one can check linux/Documentation/power and attached i.MX

Linux Manual low power chapters. Please follow User Guide

recommendations which modules could be powered off.

Best regards
igor
