From b88ce2a41562d1a9554f209e0f31a32d9f473794 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Mon, 26 Nov 2012 10:03:06 +0100 Subject: ACPI / PM: Allow attach/detach routines to change device power states Make it possible to ask the routines used for adding/removing devices to/from the general ACPI PM domain, acpi_dev_pm_attach() and acpi_dev_pm_detach(), respectively, to change the power states of devices so that they are put into the full-power state automatically by acpi_dev_pm_attach() and into the lowest-power state available automatically by acpi_dev_pm_detach().
