menu "CAN Device Drivers"

config CONFIG_CAN_VCAN
	tristate "Virtual Local CAN Interface (vcan)"
	---help---
	  Similar to the network loopback devices, vcan offers a
	  virtual local CONFIG_CAN interface.

	  This driver can also be built as a module.  If so, the module
	  will be called vcan.

config CONFIG_CAN_SLCAN
	tristate "Serial / USB serial CAN Adaptors (slcan)"
	depends on CONFIG_TTY
	---help---
	  CONFIG_CAN driver for several 'low cost' CONFIG_CAN interfaces that are attached
	  via serial lines or via CONFIG_USB-to-serial adapters using the LAWICEL
	  ASCII protocol. The driver implements the tty linediscipline N_SLCAN.

	  As only the sending and receiving of CONFIG_CAN frames is implemented, this
	  driver should work with the (serial/CONFIG_USB) CONFIG_CAN hardware from:
	  www.canusb.com / www.can232.com / www.mictronics.de / www.canhack.de

	  Userspace tools to attach the SLCAN line discipline (slcan_attach,
	  slcand) can be found in the can-utils at the SocketCAN SVN, see
	  http://developer.berlios.de/projects/socketcan for details.

	  The slcan driver supports up to 10 CONFIG_CAN netdevices by default which
	  can be changed by the 'maxdev=xx' module option. This driver can
	  also be built as a module. If so, the module will be called slcan.

config CONFIG_CAN_DEV
	tristate "Platform CAN drivers with Netlink support"
	default y
	---help---
	  Enables the common framework for platform CONFIG_CAN drivers with Netlink
	  support. This is the standard library for CONFIG_CAN drivers.
	  If unsure, say Y.

if CONFIG_CAN_DEV

config CONFIG_CAN_CALC_BITTIMING
	bool "CAN bit-timing calculation"
	default y
	---help---
	  If enabled, CONFIG_CAN bit-timing parameters will be calculated for the
	  bit-rate specified via Netlink argument "bitrate" when the device
	  get started. This works fine for the most common CONFIG_CAN controllers
	  with standard bit-rates but may fail for exotic bit-rates or CONFIG_CAN
	  source clock frequencies. Disabling saves some space, but then the
	  bit-timing parameters must be specified directly using the Netlink
	  arguments "tq", "prop_seg", "phase_seg1", "phase_seg2" and "sjw".
	  If unsure, say Y.

config CONFIG_CAN_LEDS
	bool "Enable LED triggers for Netlink based drivers"
	depends on CONFIG_LEDS_CLASS
	select CONFIG_LEDS_TRIGGERS
	---help---
	  This option adds two LED triggers for packet receive and transmit
	  events on each supported CONFIG_CAN device.

	  Say Y here if you are working on a system with led-class supported
	  LEDs and you want to use them as canbus activity indicators.

config CONFIG_CAN_AT91
	tristate "Atmel AT91 onchip CAN controller"
	depends on (CONFIG_ARCH_AT91 || CONFIG_COMPILE_TEST) && CONFIG_HAS_IOMEM
	---help---
	  This is a driver for the SoC CONFIG_CAN controller in Atmel's AT91SAM9263
	  and AT91SAM9X5 processors.

config CONFIG_CAN_BFIN
	depends on CONFIG_BF534 || CONFIG_BF536 || CONFIG_BF537 || CONFIG_BF538 || CONFIG_BF539 || CONFIG_BF54x
	tristate "Analog Devices Blackfin on-chip CAN"
	---help---
	  Driver for the Analog Devices Blackfin on-chip CONFIG_CAN controllers

	  To compile this driver as a module, choose CONFIG_M here: the
	  module will be called bfin_can.

config CONFIG_CAN_FLEXCAN
	tristate "Support for Freescale FLEXCAN based chips"
	depends on CONFIG_ARM || CONFIG_PPC
	---help---
	  Say Y here if you want to support for Freescale FlexCAN.

config CONFIG_CAN_GRCAN
	tristate "Aeroflex Gaisler GRCAN and GRHCAN CAN devices"
	depends on CONFIG_OF && CONFIG_HAS_DMA
	---help---
	  Say Y here if you want to use Aeroflex Gaisler GRCAN or GRHCAN.
	  Note that the driver supports little endian, even though little
	  endian syntheses of the cores would need some modifications on
	  the hardware level to work.

config CONFIG_CAN_JANZ_ICAN3
	tristate "Janz VMOD-ICAN3 Intelligent CAN controller"
	depends on CONFIG_MFD_JANZ_CMODIO
	---help---
	  Driver for Janz VMOD-ICAN3 Intelligent CONFIG_CAN controller module, which
	  connects to a MODULbus carrier board.

	  This driver can also be built as a module. If so, the module will be
	  called janz-ican3.ko.

config CONFIG_CAN_SUN4I
	tristate "Allwinner A10 CAN controller"
	depends on CONFIG_MACH_SUN4I || CONFIG_MACH_SUN7I || CONFIG_COMPILE_TEST
	---help---
	  Say Y here if you want to use CONFIG_CAN controller found on Allwinner
	  A10/A20 SoCs.

	  To compile this driver as a module, choose CONFIG_M here: the module will
	  be called sun4i_can.

config CONFIG_CAN_TI_HECC
	depends on CONFIG_ARM
	tristate "TI High End CAN Controller"
	---help---
	  Driver for TI HECC (High End CONFIG_CAN Controller) module found on many
	  TI devices. The device specifications are available from www.ti.com

config CONFIG_CAN_XILINXCAN
	tristate "Xilinx CAN"
	depends on CONFIG_ARCH_ZYNQ || CONFIG_ARM64 || CONFIG_MICROBLAZE || CONFIG_COMPILE_TEST
	depends on CONFIG_COMMON_CLK && CONFIG_HAS_IOMEM
	---help---
	  Xilinx CONFIG_CAN driver. This driver supports both soft AXI CONFIG_CAN IP and
	  Zynq CANPS IP.

config CONFIG_PCH_CAN
	tristate "Intel EG20T PCH CAN controller"
	depends on CONFIG_PCI && (CONFIG_X86_32 || CONFIG_COMPILE_TEST)
	---help---
	  This driver is for PCH CONFIG_CAN of Topcliff (Intel EG20T PCH) which
	  is an IOH for x86 embedded processor (Intel Atom E6xx series).
	  This driver can access CONFIG_CAN bus.

	---help---
	  Say Y here if you want the CONFIG_CAN device drivers to produce a bunch of
	  debug messages to the system log.  Select this if you are having
	  a problem with CONFIG_CAN support and want to see more of what is going
	  on.
