Hello,
We are using a DM3730 with the TPS65951 on our custom board. For our customer is low standby power consumption important.
I would like to know whether we can wake-up from pin SYS_CLKOUT1 (in mux mode 4 (gpio)). This pin is connected to a touch screen which generates an interrupt when the touch screen is touched. Upon this touch, we would like the controller to become active.
This GPIO is in the Wake-up domain, so all the other domains should be set to inactive.
If only the wake-up domain is powered, can we then still wake-up on this touch interrupt?
Could you point me to some registers which should be set to bring all other domains to inactive?
We are now using the command "echo mem > /sys/power/state" , but not all domains are powered down.
p.s. Can we set a GPIO to a specific level (not in wake-up domain), when the dm3730 is suspended (echo mem > /sys/power/state). We would like maintain the actual gpio state (output high).
Thanks
Erwin
