help
Use additional GPIO space in addition to the GPIO's the SOC
provides. This allows expanding the GPIO space for use with
GPIO expanders.

config SAMSUNG_PM_DEBUG
bool "S3C2410 PM Suspend debug"
depends on PM
help
Say Y here if you want verbose debugging from the PM Suspend and
Resume code. See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>
for more information.
config S3C_PM_DEBUG_LED_SMDK
bool "SMDK LED suspend/resume debugging"
depends on PM && (MACH_SMDK6410)
help
Say Y here to enable the use of the SMDK LEDs on the baseboard
for debugging of the state of the suspend and resume process.
Note, this currently only works for S3C64XX based SMDK boards.
config SAMSUNG_PM_CHECK
bool "S3C2410 PM Suspend Memory CRC"
depends on PM && CRC32
help
Enable the PM code's memory area checksum over sleep. This option
will generate CRCs of all blocks of memory, and store them before
going to sleep. The blocks are then checked on resume for any
errors.
Note, this can take several seconds depending on memory size
and CPU speed.
See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>
config SAMSUNG_PM_CHECK_CHUNKSIZE
int "S3C2410 PM Suspend CRC Chunksize (KiB)"
depends on PM && SAMSUNG_PM_CHECK
default 64
help
Set the chunksize in Kilobytes of the CRC for checking memory
corruption over suspend and resume. A smaller value will mean that
the CRC data block will take more memory, but wil identify any
faults with better precision.
See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>
