From 263b4c1a64bc12470684aeaf7c44f03d31716819 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Thu, 27 Aug 2015 04:37:19 +0200 Subject: ACPI / property: Expose data-only subnodes via sysfs Add infrastructure needed to expose data-only subnodes of ACPI device objects introduced previously via sysfs. Each data-only subnode is represented as a sysfs directory under the directory corresponding to its parent object (a device or a data-only subnode). Each of them has a "path" attribute (containing the full ACPI namespace path to the object the subnode data come from) at this time. Signed-off-by: Rafael J.
