   3 config CAN_VCAN
   4         tristate "Virtual Local CAN Interface (vcan)"
   5         ---help---
   6           Similar to the network loopback devices, vcan offers a
   7           virtual local CAN interface.
   8
   9           This driver can also be built as a module.  If so, the module
  10           will be called vcan.

  12 config CAN_SLCAN
  13         tristate "Serial / USB serial CAN Adaptors (slcan)"
  14         depends on TTY
  15         ---help---
  16           CAN driver for several 'low cost' CAN interfaces that are attached
  17           via serial lines or via USB-to-serial adapters using the LAWICEL
  18           ASCII protocol. The driver implements the tty linediscipline N_SLCAN.
  19
  20           As only the sending and receiving of CAN frames is implemented, this
  21           driver should work with the (serial/USB) CAN hardware from:
  22           www.canusb.com / www.can232.com / www.mictronics.de / www.canhack.de
  23
  24           Userspace tools to attach the SLCAN line discipline (slcan_attach,
  25           slcand) can be found in the can-utils at the SocketCAN SVN, see
  26           http://developer.berlios.de/projects/socketcan for details.
  27
  28           The slcan driver supports up to 10 CAN netdevices by default which
  29           can be changed by the 'maxdev=xx' module option. This driver can
  30           also be built as a module. If so, the module will be called slcan.

  32 config CAN_DEV
  33         tristate "Platform CAN drivers with Netlink support"
  34         default y
  35         ---help---
  36           Enables the common framework for platform CAN drivers with Netlink
  37           support. This is the standard library for CAN drivers.
  38           If unsure, say Y.

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

  55 config CAN_LEDS

  57         depends on LEDS_CLASS
  58         select LEDS_TRIGGERS
  59         ---help---
  60           This option adds two LED triggers for packet receive and transmit
  61           events on each supported CAN device.
  62
  63           Say Y here if you are working on a system with led-class supported
  64           LEDs and you want to use them as canbus activity indicators.
  65
  66 config CAN_AT91
  67         tristate "Atmel AT91 onchip CAN controller"

  71           and AT91SAM9X5 processors.

  91         ---help---
  92           Say Y here if you want to use Aeroflex Gaisler GRCAN or GRHCAN.
  93           Note that the driver supports little endian, even though little
  94           endian syntheses of the cores would need some modifications on
  95           the hardware level to work.
