Hi Sreekanth, for the gpio-keys driver, we get the power button gpio number from the firmware (SFI table). If you want to see the code for this, it is in arch/x86/platform/mrst/mrst.c Kristen _______________________________________________ MeeGo-dev mailing list [email protected] http://lists.meego.com/listinfo/meego-dev http://wiki.meego.com/Mailing_list_guidelines
