3config 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
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 ARCH_OMAP3
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. The device specifications are available from www.ti.com
79
80config CAN_MCP251X
81	tristate "Microchip MCP251x SPI CAN controllers"
82	depends on SPI && HAS_DMA
83	---help---
84	  Driver for the Microchip MCP251x SPI CAN controllers.
85
86config CAN_BFIN
87	depends on BF534 || BF536 || BF537 || BF538 || BF539 || BF54x
88	tristate "Analog Devices Blackfin on-chip CAN"
89	---help---
90	  Driver for the Analog Devices Blackfin on-chip CAN controllers
91
92	  To compile this driver as a module, choose M here: the
93	  module will be called bfin_can.
94
95config CAN_JANZ_ICAN3
96	tristate "Janz VMOD-ICAN3 Intelligent CAN controller"
97	depends on MFD_JANZ_CMODIO
98	---help---
99	  Driver for Janz VMOD-ICAN3 Intelligent CAN controller module, which
100	  connects to a MODULbus carrier board.
101
102	  This driver can also be built as a module. If so, the module will be
103	  called janz-ican3.ko.
104
105config CAN_FLEXCAN
106	tristate "Support for Freescale FLEXCAN based chips"
107	depends on ARM || PPC
108	---help---
109	  Say Y here if you want to support for Freescale FlexCAN.
110
111config PCH_CAN
112	tristate "Intel EG20T PCH CAN controller"
113	depends on PCI
114	---help---
115	  This driver is for PCH CAN of Topcliff (Intel EG20T PCH) which
116	  is an IOH for x86 embedded processor (Intel Atom E6xx series).
117	  This driver can access CAN bus.
118
119config CAN_GRCAN
120	tristate "Aeroflex Gaisler GRCAN and GRHCAN CAN devices"
121	depends on OF
122	---help---
123	  Say Y here if you want to use Aeroflex Gaisler GRCAN or GRHCAN.
124	  Note that the driver supports little endian, even though little
125	  endian syntheses of the cores would need some modifications on
126	  the hardware level to work.

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