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 (ARCH_AT91 || COMPILE_TEST) && HAS_IOMEM 69 ---help--- 70 This is a driver for the SoC CAN controller in Atmel's AT91SAM9263 71 and AT91SAM9X5 processors. 72 73config CAN_BFIN 74 depends on BF534 || BF536 || BF537 || BF538 || BF539 || BF54x 75 tristate "Analog Devices Blackfin on-chip CAN" 76 ---help--- 77 Driver for the Analog Devices Blackfin on-chip CAN controllers 78 79 To compile this driver as a module, choose M here: the 80 module will be called bfin_can. 81 82config CAN_FLEXCAN 83 tristate "Support for Freescale FLEXCAN based chips" 84 depends on ARM || PPC 85 ---help--- 86 Say Y here if you want to support for Freescale FlexCAN. 87 88config CAN_GRCAN 89 tristate "Aeroflex Gaisler GRCAN and GRHCAN CAN devices" 90 depends on OF && HAS_DMA 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. 96 97config CAN_JANZ_ICAN3 98 tristate "Janz VMOD-ICAN3 Intelligent CAN controller" 99 depends on MFD_JANZ_CMODIO 100 ---help--- 101 Driver for Janz VMOD-ICAN3 Intelligent CAN controller module, which 102 connects to a MODULbus carrier board. 103 104 This driver can also be built as a module.
