platform_bus: allow custom extensions to system PM methods

2010-05-21T16:37:30Z

When runtime PM for platform_bus was added, it allowed for platforms to customize the runtime PM methods since they are defined as weak symbols. This patch allows platforms to also extend the system PM methods with custom hooks so runtime PM and system PM extensions can be managed together by custom platform-specific code.

platform: Make platform resource input parameters const

Make the platform resource input parameters of platform_device_add_resources() and platform_device_register_simple() const, as the resources are copied and never modified. Signed-off-by: Geert Uytterhoeven Acked-by: Greg Kroah-Hartman

driver core: Early dev_name() depends on slab_is_available().

2010-05-13T08:56:56Z

The early dev_name() setup needs to do an allocation which can only be satisfied under slab_is_available() conditions. Some of the early platform drivers may be initialized before this point, and those still need to contend themselves with an empty dev_name. This fixes up a regression with the SH earlyprintk which was bailing out prior to hitting the early probe path due to not being able to satisfy the early allocation. Other early platform drivers (such as the early timers) that need to match the dev name are sufficiently late that allocations are already possible. Signed-off-by: Paul Mundt

PM / platform_bus: Allow runtime PM by default

2010-05-10T21:10:13Z

Currently the default runtime PM callbacks for platform devices return -ENOSYS, preventing the use of runtime PM platforms until they have provided at least a default implementation. This hinders the use of runtime PM by devices which work with many platforms such as memory mapped devices, MFDs and on chip IPs shared by multiple architectures. Change the default implementation to the standard pm_generic_runtime one, allowing drivers to use runtime PM without per-architecture changes.
