| 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. |
| 11 | |
| 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. |
| 31 | |
| 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. |
| 39 | |

| 41 | |
| 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. |
| 54 | |
| 55 | config CAN_LEDS |
| 56 | bool "Enable LED triggers for Netlink based drivers" |
| 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. |

| 70 | This is a driver for the SoC CAN controller in Atmel's AT91SAM9263 |
| 71 | and AT91SAM9X5 processors. |

| 97 | called janz-ican3.ko. |

| 117 | Say Y here if you want to use Aeroflex Gaisler GRCAN or GRHCAN. |
| 118 | Note that the driver supports little endian, even though little |
| 119 | endian syntheses of the cores would need some modifications on |
| 120 | the hardware level to work. |
