[ARM] Move include/asm-arm/arch-* to arch/arm/*/include/mach

[ARM] 5027/1: Fixed random memory corruption on pxa suspend cycle.

2008-05-04T10:06:05+00:00

Each time a pxa type cpu went in suspend, a portion of kmalloc memory was corrupted. The issue was an incorrect length allocation introduced by the commit 711be5ccfe9a02ba560aa918a008c31ea4760163 for the save registers array (=> overflow). Signed-off-by: Robert Jarzmik Signed-off-by: Russell King

PM: Move definition of struct pm_ops to suspend.h

2007-10-18T21:37:18+00:00

Move the definition of 'struct pm_ops' and related functions from to . There are, at least, the following reasons to do that: * 'struct pm_ops' is specifically related to suspend and not to the power management in general. * As long as 'struct pm_ops' is defined in , any modification of it causes the entire kernel to be recompiled, which is unnecessary and annoying. * Some suspend-related features are already defined in , so it is logical to move the definition of 'struct pm_ops' into there. * 'struct hibernation_ops', being the hibernation-related counterpart of 'struct pm_ops', is defined in .

[ARM] 4489/1: pxa: split pxa_cpu_suspend to processor specific ones

2007-07-20T16:25:20+00:00

1. split pxa_cpu_suspend to pxa25x_cpu_suspend and pxa27x_cpu_suspend and make pxa25x_cpu_pm_enter() and pxa27x_cpu_pm_enter() to invoke the corresponding _suspend functions, thus remove all those ugly #ifdef .. #endif out of sleep.S 2. move the declarations of those suspend functions to pm.h note: this is not a clean enough solution until all the pxa25x and pxa27x specific part is further removed out of sleep.S, sleep.S is supposed to contain generic code only Signed-off-by: eric miao Signed-off-by: Russell King

[ARM] 4488/1: pxa: move pxa25x/pxa27x specific code out of pm.c

2007-07-20T16:25:10+00:00

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 Signed-off-by: Russell King

[ARM] pxa: remove useless pxa_pm_finish() function

2007-07-12T13:27:53+00:00

pxa_pm_finish() does nothing but return zero. The core code does nothing with this return value, and will not try to call the finish method in the pm_ops structure if it is NULL. Therefore, we can remove this useless function. Signed-off-by: Russell King

[ARM] 3113/1: PXA: Allow machines to override (and also reuse) pxa pm functions

2005-11-06T15:03:23+00:00

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. Signed-off-by: Richard Purdie Signed-off-by: Russell King
