This allows expanding the GPIO space for use with GPIO expanders. config S3C_GPIO_SPACE int "Space between gpio banks" default 0 help Add a number of spare GPIO entries between each bank for debugging purposes. This allows any problems where an counter overflows from one bank to another to be caught, at the expense of using a little more memory. config S3C_GPIO_TRACK bool help Internal configuration option to enable the s3c specific gpio chip tracking if the platform requires it. # 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_HSMMC3 bool help Compile in platform device definitions for HSMMC channel 3 config S3C_DEV_HWMON bool help Compile in platform device definitions for HWMON config S3C_DEV_I2C1 bool help Compile in platform device definitions for I2C channel 1 config S3C_DEV_I2C2 bool help Compile in platform device definitions for I2C channel 2 config S3C_DEV_I2C3 bool help Compile in platform device definition for I2C controller 3 config S3C_DEV_I2C4 bool help Compile in platform device definition for I2C controller 4 config S3C_DEV_I2C5 bool help Compile in platform device definition for I2C controller 5 config S3C_DEV_I2C6 bool help Compile in platform device definition for I2C controller 6 config S3C_DEV_I2C7 bool help Compile in platform device definition for I2C controller 7 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_WDT bool default y if ARCH_S3C2410 help Complie in platform device definition for Watchdog Timer config S3C_DEV_NAND bool help Compile in platform device definition for NAND controller config S3C_DEV_ONENAND bool help Compile in platform device definition for OneNAND controller config S3C_DEV_RTC bool help Complie in platform device definition for RTC config SAMSUNG_DEV_ADC bool help Compile in platform device definition for ADC controller config SAMSUNG_DEV_IDE bool help Compile in platform device definitions for IDE config S3C64XX_DEV_SPI0 bool help Compile in platform device definitions for S3C64XX's type SPI controller 0 config S3C64XX_DEV_SPI1 bool help Compile in platform device definitions for S3C64XX's type SPI controller 1 config S3C64XX_DEV_SPI2 bool help Compile in platform device definitions for S3C64XX's type SPI controller 2 config SAMSUNG_DEV_TS bool help Common in platform device definitions for touchscreen device config SAMSUNG_DEV_KEYPAD bool help Compile in platform device definitions for keypad config SAMSUNG_DEV_PWM bool default y if ARCH_S3C2410 help Compile in platform device definition for PWM Timer config SAMSUNG_DEV_BACKLIGHT bool depends on SAMSUNG_DEV_PWM help Compile in platform device definition LCD backlight with PWM Timer config S3C24XX_PWM bool "PWM device support" select HAVE_PWM help Support for exporting the PWM timer blocks via the pwm device system # DMA config S3C_DMA bool help Internal configuration for S3C DMA core config SAMSUNG_DMADEV bool select DMADEVICES select PL330_DMA if (CPU_EXYNOS4210 || CPU_S5PV210 || CPU_S5PC100 || \ CPU_S5P6450 || CPU_S5P6440) select ARM_AMBA help Use DMA device engine for PL330 DMAC. 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 config SAMSUNG_WAKEMASK bool depends on PM help Compile support for wakeup-mask controls found on the S3C6400 and above. This code allows a set of interrupt to wakeup-mask mappings.
