Hi, This is the second version of the patch series to rework pm_ops in order to introduce the set_target() method etc. This time I've takes some Dave's comments into consideration and I've realized that a method similar to set_target() is also needed for hibernation, so I've reworked that too, a bit. The following series of patches: * introduces the .set_target() method in 'struct pm_ops' so that the platform code knows in advance what sleep state the system is going to enter (this is urgently needed by at91 and should go into 2.6.22 as a bugfix) * makes ACPI use .set_target() * adds an ACPI helper function for the devices to determine the power state to put the device into * moves the definition of 'struct pm_ops' to <include/suspend.h> * changes the name of 'struct pm_ops' to 'struct platform_suspend_operations' and modifies the names of some related functions and global variables accordingly * modifies 'struct platform_suspend_operations' so that .prepare() and .finish() don't take arguments (.enter() still takes the state argument, because some platforms don't need to implement the other callbacks) * reworks 'struct hibernation_ops' to add the new method analogous to .set_target() * renames 'struct hibernation_ops' to 'struct hibernation_platform_operations' (in analogy with 'struct platform_suspend_operations') The details are in the changelogs. The series have been compilation-tested on x86_64 and I'm going to compile it for all of the affected platforms. Comments welcome.
