[ARM] 3113/1: PXA: Allow machines to override (and also reuse) pxa pm functions Patch from Richard Purdie Update the PXA pm.c file to allow machines (such as the Sharp Zaurus) to override the standard pm functions but reuse/wrap them where needed. The init call is made slightly earlier to give machine code an init level to override them in removing any race.

[ARM] 4488/1: pxa: move pxa25x/pxa27x specific code out of pm.c 1. introduce a structure pxa_cpu_pm_fns for pxa25x/pxa27x specific operations as follows: struct pxa_cpu_pm_fns { int save_size; void (*save)(unsigned long *); void (*restore)(unsigned long *); int (*valid)(suspend_state_t state); void (*enter)(suspend_state_t state); } 2. processor specific registers saving and restoring are performed by calling the corresponding (*save) and (*restore) 3. pxa_cpu_pm_fns->save_size should be initialized to the required size for processor specific registers saving, the allocated memory address will be passed to (*save) and (*restore) memory allocation happens early in pxa_pm_init(), and save_size should be assigned prior to this (which is usually true, since pxa_pm_init() happens in device_initcall() 4. there're some redundancies for those SLEEP_SAVE_XXX and related macros, will be fixed later, one way possible is for the system devices to handle the specific registers saving and restoring Signed-off-by: eric miao <eric.y.miao@gmail.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
