PM/UART 3.5-rc5: UART Rx wakeups not quite right?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Are there any patches floating around to fix UART Rx wakeups for 3.5?

I have a GUMSTIX Overo with various things hanging off the UARTs, one
of which (on ttyO0) sends in periodic (GPS) data.

I don't want this data to wake the OMAP from system suspend.

I would normally disable UART Rx wakeup for ttyO0:
# echo "disabled" > /sys/devices/platform/omap_uart.0/power/wakeup

This works on 3.5-rc5 (i.e. I can suspend, and not immediately wake) UNTIL
I run an application that opens /dev/ttyO0.

At this point when entering system suspend ttyO0 wakes the OMAP up
immediately, even though the SYSFS reports the wakeup as "disabled".

Any ideas?

Cheers,
Joe
