If I make imx6solo to sleep mode by a gpio from a car's ACC-GPIO,how can I do? It likes thta the cpu to sleep(1.34V-1.5V-3.3V is always on) when cpu detect the gpio change to 1 from 0,and then when the gpio goes to 0 from1,cpu can wanke up and goto normallywork mode.
Am I right?Can any gpio of IMX6SOLO do this function?Can I need use the onoff/stby_req/on_req?

Hi
any gpio interrupt can wake processor from low power modes, no need for
any manupulations with ONOFF or POWER buttons. So one can enable any gpio
with interrupt for waking, please use wake examples in unit tests package (for example
imx-test/.. mxc_rtc/rtcwakeup.c :
www.nxp.com/lgfiles/NMG/MAD/YOCTO/imx-test-5.7.tar.gz
and description in sect.21.1.5 Unit Test atatched Linux Manual.
Best regards
igor
