    +What: /sys/kernel/debug/ec/*/{gpe,use_global_lock,io}
    +Date: July 2010
    +Contact: Thomas Renninger <>
    +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):
    +The io file is binary and a userspace tool located here:
    +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.
