If so, the module 10 will be called vcan. 11 12config 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 32config 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 40if CAN_DEV 41 42config 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 55config 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. 65 66config CAN_AT91 67 tristate "Atmel AT91 onchip CAN controller" 68 depends on ARM 69 ---help--- 70 This is a driver for the SoC CAN controller in Atmel's AT91SAM9263 71 and AT91SAM9X5 processors. 72 73config CAN_TI_HECC 74 depends on ARM 75 tristate "TI High End CAN Controller" 76 ---help--- 77 Driver for TI HECC (High End CAN Controller) module found on many 78 TI devices.
