Function Documentation

int s3c2410_cpu_suspend ( unsigned  long)
void s3c_cpu_resume ( void  )
void s3c_pm_configure_extint ( void  )

s3c_pm_configure_extint() - ensure pins are correctly set for IRQ

Setup all the necessary GPIO pins for waking the system on external interrupt.

Definition at line 119 of file pm.c.

void s3c_pm_do_restore ( struct sleep_save ptr,
int  count 

s3c_pm_do_restore() - restore register values from the save list. : Pointer to an array of registers. : Size of the ptr array.

Restore the register values saved from s3c_pm_do_save().

Note, we do not use S3C_PMDBG() in here, as the system may not have restore the UARTs state yet

Definition at line 187 of file pm.c.

void s3c_pm_do_restore_core ( struct sleep_save ptr,
int  count 

s3c_pm_do_restore_core() - early restore register values from save list.

This is similar to s3c_pm_do_restore() except we try and minimise the side effects of the function in case registers that hardware might need to work has been restored.

WARNING: Do not put any debug in here that may effect memory or use peripherals, as things may be changing!

Definition at line 208 of file pm.c.

void s3c_pm_do_save ( struct sleep_save ptr,
int  count 

s3c_pm_do_save() - save a set of registers for restoration on resume. : Pointer to an array of registers. : Size of the ptr array.

Run through the list of registers given, saving their contents in the array for later restoration when we wakeup.

void s3c_pm_restore_core ( void  )

Definition at line 138 of file pm.c.

void s3c_pm_save_core ( void  )

Definition at line 144 of file pm.c.

void samsung_pm_restore_gpios ( void  )

samsung_pm_restore_gpios() - restore the state of the gpios after sleep.

Restore the state of the GPIO pins after sleep, which may involve ensuring that we do not glitch the state of the pins from that the bootloader's resume code has done.

Definition at line 367 of file pm-gpio.c.

void samsung_pm_save_gpios ( void  )

samsung_pm_save_gpios() - save the state of the GPIOs for restoring after sleep.

Save the GPIO states for resotration on resume. See samsung_pm_restore_gpios().

samsung_pm_save_gpios() - Save the state of the GPIO banks.

For all the GPIO banks, save the state of each one ready for going into a suspend mode.
