GPIOlib shall be compiled only for S3C64XX and S5P series of processors. config S3C_GPIO_CFG_S3C24XX bool help Internal configuration to enable S3C24XX style GPIO configuration functions. config S3C_GPIO_CFG_S3C64XX bool help Internal configuration to enable S3C64XX style GPIO configuration functions. config S5P_GPIO_CFG_S5PC1XX bool help Internal configuration to enable S5PC1XX style GPIO configuration functions. config S3C_GPIO_PULL_UPDOWN bool help Internal configuration to enable the correct GPIO pull helper config S3C_GPIO_PULL_DOWN bool help Internal configuration to enable the correct GPIO pull helper config S3C_GPIO_PULL_UP bool help Internal configuration to enable the correct GPIO pull helper config SAMSUNG_GPIO_EXTRA int "Number of additional GPIO pins" default 0 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. # ADC driver config S3C_ADC bool "ADC common driver support" help Core support for the ADC block found in the Samsung SoC systems for drivers such as the touchscreen and hwmon to use to share this resource. # device definitions to compile in config S3C_DEV_HSMMC bool help Compile in platform device definitions for HSMMC code config S3C_DEV_HSMMC1 bool help Compile in platform device definitions for HSMMC channel 1 config S3C_DEV_HSMMC2 bool help Compile in platform device definitions for HSMMC channel 2 config S3C_DEV_I2C1 bool help Compile in platform device definitions for I2C channel 1 config S3C_DEV_FB bool help Compile in platform device definition for framebuffer config S3C_DEV_USB_HOST bool help Compile in platform device definition for USB host. config S3C_DEV_USB_HSOTG bool help Compile in platform device definition for USB high-speed OtG config S3C_DEV_NAND bool help Compile in platform device definition for NAND controller config S3C64XX_DEV_SPI bool help Compile in platform device definitions for S3C64XX's type SPI controllers. comment "Power management" 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 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 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 endif
