4 tristate "Virtual Local CAN Interface (vcan)"
6 Similar to the network loopback devices, vcan offers a
7 virtual local CAN interface.
9 This driver can also be built as a module. If so, the module
13 tristate "Virtual CAN Tunnel (vxcan)"
15 Similar to the virtual ethernet driver veth, vxcan implements a
16 local CAN traffic tunnel between two virtual CAN network devices.
17 When creating a vxcan, two vxcan devices are created as pair.
18 When one end receives the packet it appears on its pair and vice
19 versa. The vxcan can be used for cross namespace communication.
21 In opposite to vcan loopback devices the vxcan only forwards CAN
22 frames to its pair and does *not* provide a local echo of sent
23 CAN frames. To disable a potential echo in af_can.c the vxcan driver
24 announces IFF_ECHO in the interface flags. To have a clean start
25 in each namespace the CAN GW hop counter is set to zero.
27 This driver can also be built as a module. If so, the module
31 tristate "Serial / USB serial CAN Adaptors (slcan)"
34 CAN driver for several 'low cost' CAN interfaces that are attached
35 via serial lines or via USB-to-serial adapters using the LAWICEL
36 ASCII protocol. The driver implements the tty linediscipline N_SLCAN.
38 As only the sending and receiving of CAN frames is implemented, this
39 driver should work with the (serial/USB) CAN hardware from:
40 www.canusb.com / www.can232.com / www.mictronics.de / www.canhack.de
42 Userspace tools to attach the SLCAN line discipline (slcan_attach,
43 slcand) can be found in the can-utils at the SocketCAN SVN, see
44 http://developer.berlios.de/projects/socketcan for details.
46 The slcan driver supports up to 10 CAN netdevices by default which
47 can be changed by the 'maxdev=xx' module option. This driver can
48 also be built as a module. If so, the module will be called slcan.
51 tristate "Platform CAN drivers with Netlink support"
54 Enables the common framework for platform CAN drivers with Netlink
55 support. This is the standard library for CAN drivers.
60 config CAN_CALC_BITTIMING
61 bool "CAN bit-timing calculation"
64 If enabled, CAN bit-timing parameters will be calculated for the
65 bit-rate specified via Netlink argument "bitrate" when the device
66 get started. This works fine for the most common CAN controllers
67 with standard bit-rates but may fail for exotic bit-rates or CAN
68 source clock frequencies. Disabling saves some space, but then the
69 bit-timing parameters must be specified directly using the Netlink
70 arguments "tq", "prop_seg", "phase_seg1", "phase_seg2" and "sjw".
74 bool "Enable LED triggers for Netlink based drivers"
76 # The netdev trigger (LEDS_TRIGGER_NETDEV) should be able to do
77 # everything that this driver is doing. This is marked as broken
78 # because it uses stuff that is intended to be changed or removed.
79 # Please consider switching to the netdev trigger and confirm it
80 # fulfills your needs instead of fixing this driver.
84 This option adds two LED triggers for packet receive and transmit
85 events on each supported CAN device.
87 Say Y here if you are working on a system with led-class supported
88 LEDs and you want to use them as canbus activity indicators.
91 tristate "Atmel AT91 onchip CAN controller"
92 depends on (ARCH_AT91 || COMPILE_TEST) && HAS_IOMEM
94 This is a driver for the SoC CAN controller in Atmel's AT91SAM9263
95 and AT91SAM9X5 processors.
98 tristate "Support for Freescale FLEXCAN based chips"
99 depends on OF && HAS_IOMEM
101 Say Y here if you want to support for Freescale FlexCAN.
104 tristate "Aeroflex Gaisler GRCAN and GRHCAN CAN devices"
105 depends on OF && HAS_DMA
107 Say Y here if you want to use Aeroflex Gaisler GRCAN or GRHCAN.
108 Note that the driver supports little endian, even though little
109 endian syntheses of the cores would need some modifications on
110 the hardware level to work.
112 config CAN_JANZ_ICAN3
113 tristate "Janz VMOD-ICAN3 Intelligent CAN controller"
114 depends on MFD_JANZ_CMODIO
116 Driver for Janz VMOD-ICAN3 Intelligent CAN controller module, which
117 connects to a MODULbus carrier board.
119 This driver can also be built as a module. If so, the module will be
120 called janz-ican3.ko.
123 tristate "Allwinner A10 CAN controller"
124 depends on MACH_SUN4I || MACH_SUN7I || COMPILE_TEST
126 Say Y here if you want to use CAN controller found on Allwinner
129 To compile this driver as a module, choose M here: the module will
134 tristate "TI High End CAN Controller"
136 Driver for TI HECC (High End CAN Controller) module found on many
137 TI devices. The device specifications are available from www.ti.com
140 tristate "Xilinx CAN"
141 depends on ARCH_ZYNQ || ARM64 || MICROBLAZE || COMPILE_TEST
142 depends on COMMON_CLK && HAS_IOMEM
144 Xilinx CAN driver. This driver supports both soft AXI CAN IP and
148 tristate "Intel EG20T PCH CAN controller"
149 depends on PCI && (X86_32 || COMPILE_TEST)
151 This driver is for PCH CAN of Topcliff (Intel EG20T PCH) which
152 is an IOH for x86 embedded processor (Intel Atom E6xx series).
153 This driver can access CAN bus.
