Hello.
I noticed that I can't longer wake up my device from standby by using a GPIO after upgrading to the v4.9 Kernel.
According to the link below it shouldn't require special configuration. I'm using a gpio3, which is on the first bank (which AFAIK is the only bank allowed to wakeup, even though the documentation doesn't mention it):
http://processors.wiki.ti.com/index.php/AM335x_Power_Management_Standby_User%27s_Guide#GPIO_wakeup
Both devices have the same config on debugfs:

How can I start debugging this?
