From 1195a098168fcacfef1cd80d05358e52fb366bf6 Mon Sep 17 00:00:00 2001 From: Thomas Renninger Date: Fri, 16 Jul 2010 13:11:31 +0200 Subject: ACPI: Provide /sys/kernel/debug/ec/... This patch provides the same information through debugfs, which previously was provided through /proc/acpi/embedded_controller/*/info This is the gpe the EC is connected to and whether the global lock gets used. The io ports used are added to /proc/ioports in another patch. Beside the fact that /proc/acpi is deprecated for quite some time, this info is not needed for applications and thus can be moved to debugfs instead of a public interface like /sys.
