+Date: July 2010
+Contact: Thomas Renninger <trenn@suse.de>
+Description:
+
+General information like which GPE is assigned to the EC and whether
+the global lock should get used.
+Knowing the EC GPE one can watch the amount of HW events related to
+the EC here (XY -> GPE number from /sys/kernel/debug/ec/*/gpe):
+/sys/firmware/acpi/interrupts/gpeXY
+
+The io file is binary and a userspace tool located here:
+ftp://ftp.suse.com/pub/people/trenn/sources/ec/
+should get used to read out the 256 Embedded Controller registers
+or writing to them.
+
+CAUTION: Do not write to the Embedded Controller if you don't know
+what you are doing! Rebooting afterwards also is a good idea.
+This can influence the way your machine is cooled and fans may
+not get switched on again after you did a wrong write.

+Description:
+ The /sys/power/wakeup_count file allows user space to put the
+ system into a sleep state while taking into account the
+ concurrent arrival of wakeup events. Reading from it returns
+ the current number of registered wakeup events and it blocks if
+ some wakeup events are being processed at the time the file is
+ read from. Writing to it will only succeed if the current
+ number of wakeup events is equal to the written value and, if
+ successful, will make the kernel abort a subsequent transition
+ to a sleep state if any wakeup events are reported after the
+ write has returned.
