From 977d2fa6b2ace7e22302a55cdc5ee6110907a9d8 Mon Sep 17 00:00:00 2001 From: Kevin Hilman Date: Thu, 13 Nov 2014 14:28:20 -0800 Subject: PM / Runtime: Kconfig: move ia64 dependency to arch/ia64/Kconfig The IA64_HP_SIM dependency on PM_RUNTIME should be done in the arch Kconfig instead of in the PM core. Move it accordingly. NOTE: arch/ia64/Kconfig currently does a 'select PM', which since commit 1eb208aea317 (PM: Make CONFIG_PM depend on (CONFIG_PM_SLEEP || CONFIG_PM_RUNTIME)) is effectively a noop unless PM_SLEEP or PM_RUNTIME are set elsewhere.

Wysocki" Date: Tue, 18 Nov 2014 01:43:42 +0100 Subject: PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is selected The number of and dependencies between high-level power management Kconfig options make life much harder than necessary. Several conbinations of them have to be tested and supported, even though some of those combinations are very rarely used in practice (if they are used in practice at all). Moreover, the fact that we have separate independent Kconfig options for runtime PM and system suspend is a serious obstacle for integration between the two frameworks. To overcome these difficulties, always select PM_RUNTIME if PM_SLEEP is set. Among other things, this will allow system suspend callbacks provided by bus types and device drivers to rely on the runtime PM framework regardless of the kernel configuration.
