In the other patch you are adding "wakeup-source" to the DT binding, but
here you mark all EC deices as wakeup sources. You need to use
device_property_read_bool(dev, "wakeup-source") and use the result in
call to device_init_wakeup().

And please also update device tree binding doc for the driver.

oops, sorry, i thought that dts property is needed to enable a wakeup source...but obviously it's not, only gpio-keys requires that.

so the dts patch is not needed, will remove in next version, thanx.

Thanks.
