4config CAN_VCAN
5	tristate "Virtual Local CAN Interface (vcan)"
6	depends on CAN
7	---help---
8	  Similar to the network loopback devices, vcan offers a
9	  virtual local CAN interface.
10
11	  This driver can also be built as a module.  If so, the module
12	  will be called vcan.
13
14config CAN_SLCAN
15	tristate "Serial / USB serial CAN Adaptors (slcan)"
16	depends on CAN
17	---help---
18	  CAN driver for several 'low cost' CAN interfaces that are attached
19	  via serial lines or via USB-to-serial adapters using the LAWICEL
20	  ASCII protocol. The driver implements the tty linediscipline N_SLCAN.
21
22	  As only the sending and receiving of CAN frames is implemented, this
23	  driver should work with the (serial/USB) CAN hardware from:
24	  www.canusb.com / www.can232.com / www.mictronics.de / www.canhack.de
25
26	  Userspace tools to attach the SLCAN line discipline (slcan_attach,
27	  slcand) can be found in the can-utils at the SocketCAN SVN, see
28	  http://developer.berlios.de/projects/socketcan for details.
29
30	  The slcan driver supports up to 10 CAN netdevices by default which
31	  can be changed by the 'maxdev=xx' module option. This driver can
32	  also be built as a module. If so, the module will be called slcan.
33
34config CAN_DEV
35	tristate "Platform CAN drivers with Netlink support"
36	depends on CAN
37	default y
38	---help---
39	  Enables the common framework for platform CAN drivers with Netlink
40	  support. This is the standard library for CAN drivers.
41	  If unsure, say Y.
42
43config CAN_CALC_BITTIMING
44	bool "CAN bit-timing calculation"
45	depends on CAN_DEV
46	default y
47	---help---
48	  If enabled, CAN bit-timing parameters will be calculated for the
49	  bit-rate specified via Netlink argument "bitrate" when the device
50	  get started. This works fine for the most common CAN controllers
51	  with standard bit-rates but may fail for exotic bit-rates or CAN
52	  source clock frequencies. Disabling saves some space, but then the
53	  bit-timing parameters must be specified directly using the Netlink
54	  arguments "tq", "prop_seg", "phase_seg1", "phase_seg2" and "sjw".
55	  If unsure, say Y.
56
57config CAN_AT91
58	tristate "Atmel AT91 onchip CAN controller"
59	depends on CAN_DEV && (ARCH_AT91SAM9263 || ARCH_AT91SAM9X5)
60	---help---
61	  This is a driver for the SoC CAN controller in Atmel's AT91SAM9263
62	  and AT91SAM9X5 processors.
63
64config CAN_TI_HECC
65	depends on CAN_DEV && ARCH_OMAP3
66	tristate "TI High End CAN Controller"
67	---help---
68	  Driver for TI HECC (High End CAN Controller) module found on many
69	  TI devices. The device specifications are available from www.ti.com
70
71config CAN_MCP251X
72	tristate "Microchip MCP251x SPI CAN controllers"
73	depends on CAN_DEV && SPI && HAS_DMA
74	---help---
75	  Driver for the Microchip MCP251x SPI CAN controllers.
76
77config CAN_BFIN

79	tristate "Analog Devices Blackfin on-chip CAN"
80	---help---
81	  Driver for the Analog Devices Blackfin on-chip CAN controllers
82
83	  To compile this driver as a module, choose M here: the
84	  module will be called bfin_can.
85
86config CAN_JANZ_ICAN3
87	tristate "Janz VMOD-ICAN3 Intelligent CAN controller"
88	depends on CAN_DEV && MFD_JANZ_CMODIO
89	---help---
90	  Driver for Janz VMOD-ICAN3 Intelligent CAN controller module, which
91	  connects to a MODULbus carrier board.
92
93	  This driver can also be built as a module. If so, the module will be
94	  called janz-ican3.ko.

96config HAVE_CAN_FLEXCAN

98
99config CAN_FLEXCAN
100	tristate "Support for Freescale FLEXCAN based chips"
101	depends on CAN_DEV && HAVE_CAN_FLEXCAN
102	---help---
103	  Say Y here if you want to support for Freescale FlexCAN.
104
105config PCH_CAN
106	tristate "Intel EG20T PCH CAN controller"
107	depends on CAN_DEV && PCI
108	---help---
109	  This driver is for PCH CAN of Topcliff (Intel EG20T PCH) which
110	  is an IOH for x86 embedded processor (Intel Atom E6xx series).
111	  This driver can access CAN bus.
112
113config CAN_GRCAN
114	tristate "Aeroflex Gaisler GRCAN and GRHCAN CAN devices"
115	depends on CAN_DEV && OF
116	---help---
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.

139	  debug messages to the system log.  Select this if you are having
140	  a problem with CAN support and want to see more of what is going
141	  on.
