config DEV_NULL
	bool "Enable /dev/null"
	default y

config DEV_ZERO
	bool "Enable /dev/zero"
	default y

config LOOP
	bool "Enable loop device"
	default n
	---help---
		Supports the standard loop device that can be used to export a
		file (or character device) as a block device.  See losetup() and
		loteardown() in include/nuttx/fs/fs.h.

config RAMDISK
	bool "RAM disk support"
	default n
	---help---
		Can be used to set up a block of memory or (read-only) FLASH as
		a block driver that can be mounted as a files system.  See
		include/nuttx/ramdisk.h.

config RAMLOG
	bool "RAM log message support"
	default n
	---help---
		This is a driver that was intended to support debugging output,
		aka syslogging, when the normal serial output is not available.
		For example, if you are using a telnet or USB serial console,
		the debug output will get lost.

		This driver is similar to a pipe in that it saves the debugging
		output in a FIFO in RAM.  It differs from a pipe in numerous
		details as needed to support logging.

config CAN
	bool "CAN support"
	default n

config PWM
	bool "PWM support"
	default n

config I2C
	bool "I2C support"
	default y

config SPI
	bool "SPI support"
	default y
	
menuconfig ANALOG
	bool "Analog Device(adc,dac) support"
	default n
	---help---
		This directory holds implementations of analog device drivers.
		This includes drivers for Analog to Digital Conversion (ADC) as
		well as drivers for Digital to Analog Conversion (DAC).
		See include/nuttx/analog/*.h for registration information.
if ANALOG
source drivers/analog/Kconfig
endif

config BCH
	bool "BCH support"
	default n
	---help---
		Contains logic that may be used to convert a block driver into
		a character driver.  This is the complementary conversion as that
		performed by loop.c.  See include/nuttx/fs/fs.h for registration
		information.
if BCH
source drivers/bch/Kconfig
endif

menuconfig INPUT
	bool "Input device support"
	default y
	---help---
		This directory holds implementations of input device drivers.
		This includes such things as touchscreen and keypad drivers.
		See include/nuttx/input/*.h for registration information.
if INPUT
source drivers/input/Kconfig
endif

menuconfig LCD
	bool "LCD support"
	default n
	select NX_LCDDRIVER
	---help---
		Drivers for parallel and serial LCD and OLED type devices.  These
		drivers support interfaces as defined in include/nuttx/lcd/lcd.h
if LCD
source drivers/lcd/Kconfig
endif

menuconfig MMCSD
	bool "MMC/SD support"
	default n
	---help---
		Support for MMC/SD block drivers.  MMC/SD block drivers based on
		SPI and SDIO/MCI interfaces are supported.  See include/nuttx/mmcsd.h
		and include/nuttx/sdio.h for further information.

if MMCSD
source drivers/mmcsd/Kconfig
endif
	
menuconfig MTD
	bool "Memory Technology Device (MTD) support"
	default n
	---help---
		Memory Technology Device (MTD) drivers.  Some simple drivers for
		memory technologies like FLASH, EEPROM, NVRAM, etc.  See
		include/nuttx/mtd.h

		(Note: This is a simple memory interface and should not be
		confused with the "real" MTD developed at infradead.org.  This
		logic is unrelated; I just used the name MTD because I am not
		aware of any other common way to refer to this class of devices).
if MTD
source drivers/mtd/Kconfig
endif

menuconfig NETDEVICES
	bool "Network Device support"
	default n
	---help---
		Network interface drivers.  See also include/nuttx/net/net.h
if NETDEVICES
source drivers/net/Kconfig
endif

menuconfig PIPES
	bool "FIFO and named pipe drivers"
	default n
	---help---
		FIFO and named pipe drivers.  Standard interfaces are declared
		in include/unistd.h
if PIPES
source drivers/pipes/Kconfig
endif

menuconfig POWER
	bool "Power management (PM) driver interfaces"
	default n
	---help---
		Power management (PM) driver interfaces.  These interfaces are used
		to manage power usage of a platform by monitoring driver activity
		and by placing drivers into reduce power usage modes when the
		drivers are not active.
if POWER
source drivers/power/Kconfig
endif

menuconfig SENSORS
	bool "Sensors support"
	default n
	---help---
		Drivers for various sensors
if SENSORS
source drivers/sensors/Kconfig
endif

menuconfig SERCOMM_CONSOLE
	bool "Osmocom-bb serial console"
	default n
	---help---
		Sercomm is the transport used by osmocom-bb that runs on top of serial.
		See http://bb.osmocom.org/trac/wiki/nuttx-bb/run for detailed the usage
		of nuttx with sercomm.

		drivers/sercomm is only built if CONFIG_SERCOMM_CONSOLE in the NuttX
		configuration file.  If you attempt to build this driver without
		osmocom-bb, you will get compilation errors because of header files
		that are needed from the osmocom-bb.
if SERCOMM
source drivers/sercomm/Kconfig
endif

menuconfig SERIAL
	bool "Serial support"
	default y
	---help---
		Front-end character drivers for chip-specific UARTs.  This provide
		some TTY-like functionality and are commonly used (but not required for)
		the NuttX system console.  See also include/nuttx/serial/serial.h
if SERIAL
source drivers/serial/Kconfig
endif

menuconfig USBDEV
	bool "USB device support"
	default n
	---help---
		USB device drivers.  See also include/nuttx/usb/usbdev.h
if USBDEV
source drivers/usbdev/Kconfig
endif

menuconfig USBHOST
	bool "USB Host support"
	default n
	---help---
		USB host drivers.  See also include/nuttx/usb/usbhost.h
if USBHOST
source drivers/usbhost/Kconfig
endif

menuconfig WIRELESS
	bool "Wireless support"
	default n
	---help---
		Drivers for various wireless devices.
if WIRELESS
source drivers/wireless/Kconfig
