imx233 2.6.31 GPIO as wakeup source

Dear all,

 

we are completing the hw design of a new mobile device based on imx233 and SW developed on L2.631 SDK,

This device is intended to massively use linux standby and suspend to ram to optimize power consumption.

We decided to use a GPIO driven by a micro controller to wake up the OS., but we can test this function only later, when HW has been developed

 

Please can you let me know if L2.6.31_10.05 BSP support the possibility to set GPIOs as wakeup sources (for example using echo enabled > /sys/class/gpio/gpio<n>/power/wakeup)

 

 

really Thanks for any hint

 

Alberto
