+ tristate "CAN Device Drivers"
+ default y
+ depends on CAN
+ help
+ Controller Area Network (CAN) is serial communications protocol up to
+ 1Mbit/s for its original release (now known as Classical CAN) and up
+ to 8Mbit/s for the more recent CAN with Flexible Data-Rate
+ (CAN-FD). The CAN bus was originally mainly for automotive, but is now
+ widely used in marine (NMEA2000), industrial, and medical
+ applications. More information on the CAN network protocol family
+ PF_CAN is contained in <Documentation/networking/can.rst>.
+
+ This section contains all the CAN(-FD) device drivers including the
+ virtual ones. If you own such devices or plan to use the virtual CAN
+ interfaces to develop applications, say Y here.
+
+ To compile as a module, choose M here: the module will be called
+ can-dev.
+
+if CAN_DEV
+
+config CAN_VCAN
+ tristate "Virtual Local CAN Interface (vcan)"
+ help
+ Similar to the network loopback devices, vcan offers a
+ virtual local CAN interface.
+
+ This driver can also be built as a module. If so, the module
+ will be called vcan.
+
+config CAN_VXCAN
+ tristate "Virtual CAN Tunnel (vxcan)"
+ help
+ Similar to the virtual ethernet driver veth, vxcan implements a
+ local CAN traffic tunnel between two virtual CAN network devices.
+ When creating a vxcan, two vxcan devices are created as pair.
+ When one end receives the packet it appears on its pair and vice
+ versa. The vxcan can be used for cross namespace communication.
+
+ In opposite to vcan loopback devices the vxcan only forwards CAN
+ frames to its pair and does *not* provide a local echo of sent
+ CAN frames. To disable a potential echo in af_can.c the vxcan driver
+ announces IFF_ECHO in the interface flags. To have a clean start
+ in each namespace the CAN GW hop counter is set to zero.
+
+ This driver can also be built as a module. If so, the module
+ will be called vxcan.
+
+config CAN_NETLINK
+ bool "CAN device drivers with Netlink support"
+ default y
+ help
+ Enables the common framework for CAN device drivers. This is the
+ standard library and provides features for the Netlink interface such
+ as bittiming validation, support of CAN error states, device restart
+ and others.
+
+ The additional features selected by this option will be added to the
+ can-dev module.
+
+ This is required by all platform and hardware CAN drivers. If you
+ plan to use such devices or if unsure, say Y.
+
+if CAN_NETLINK
+
+config CAN_CALC_BITTIMING
+ bool "CAN bit-timing calculation"
+ default y
+ help
+ If enabled, CAN bit-timing parameters will be calculated for the
+ bit-rate specified via Netlink argument "bitrate" when the device
+ get started. This works fine for the most common CAN controllers
+ with standard bit-rates but may fail for exotic bit-rates or CAN
+ source clock frequencies. Disabling saves some space, but then the
+ bit-timing parameters must be specified directly using the Netlink
+ arguments "tq", "prop_seg", "phase_seg1", "phase_seg2" and "sjw".
+
+ The additional features selected by this option will be added to the
+ can-dev module.
+
+ If unsure, say Y.

+ tristate "Serial / USB serial ELM327 based OBD-II Interfaces (can327)"
+ depends on TTY
+ select CAN_RX_OFFLOAD
+ help
+ CAN driver for several 'low cost' OBD-II interfaces based on the
+ ELM327 OBD-II interpreter chip.
+
+ This is a best effort driver - the ELM327 interface was never
+ designed to be used as a standalone CAN interface. However, it can
+ still be used for simple request-response protocols (such as OBD II),
+ and to monitor broadcast messages on a bus (such as in a vehicle).
+
+ Please refer to the documentation for information on how to use it:
+ Documentation/networking/device_drivers/can/can327.rst
+
+ If this driver is built as a module, it will be called can327.

+ depends on OF && HAS_DMA && HAS_IOMEM
+ help
+ Say Y here if you want to use Aeroflex Gaisler GRCAN or GRHCAN.
+ Note that the driver supports little endian, even though little
+ endian syntheses of the cores would need some modifications on
+ the hardware level to work.
+
+config CAN_JANZ_ICAN3

+ depends on MFD_JANZ_CMODIO
+ help
+ Driver for Janz VMOD-ICAN3 Intelligent CAN controller module, which

+ This driver can also be built as a module. If so, the module will be
+ called janz-ican3.ko.

+config CAN_SLCAN
+ tristate "Serial / USB serial CAN Adaptors (slcan)"
+ depends on TTY
+ help
+ CAN driver for several 'low cost' CAN interfaces that are attached
+ via serial lines or via USB-to-serial adapters using the LAWICEL
+ ASCII protocol. The driver implements the tty linediscipline N_SLCAN.
+
+ As only the sending and receiving of CAN frames is implemented, this
+ driver should work with the (serial/USB) CAN hardware from:
+ www.canusb.com / www.can232.com / www.mictronics.de / www.canhack.de
+
+ Userspace tools to attach the SLCAN line discipline (slcan_attach,
+ slcand) can be found in the can-utils at the linux-can project, see
+ https://github.com/linux-can/can-utils for details.
+
+ The slcan driver supports up to 10 CAN netdevices by default which
+ can be changed by the 'maxdev=xx' module option. This driver can
+ also be built as a module. If so, the module will be called slcan.

+
+ To compile this driver as a module, choose M here: the module will
+ be called sun4i_can.
