menu "CAN Device Drivers" 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_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 SocketCAN SVN, see http://developer.berlios.de/projects/socketcan 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. config CAN_DEV tristate "Platform CAN drivers with Netlink support" default y ---help--- Enables the common framework for platform CAN drivers with Netlink support. This is the standard library for CAN drivers. If unsure, say Y. if CAN_DEV 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". If unsure, say Y. config CAN_LEDS bool "Enable LED triggers for Netlink based drivers" depends on LEDS_CLASS # The netdev trigger (LEDS_TRIGGER_NETDEV) should be able to do # everything that this driver is doing. This is marked as broken # because it uses stuff that is intended to be changed or removed. # Please consider switching to the netdev trigger and confirm it # fulfills your needs instead of fixing this driver. depends on BROKEN select LEDS_TRIGGERS ---help--- This option adds two LED triggers for packet receive and transmit events on each supported CAN device. Say Y here if you are working on a system with led-class supported LEDs and you want to use them as canbus activity indicators. config CAN_AT91 tristate "Atmel AT91 onchip CAN controller" depends on (ARCH_AT91 || COMPILE_TEST) && HAS_IOMEM ---help--- This is a driver for the SoC CAN controller in Atmel's AT91SAM9263 and AT91SAM9X5 processors. config CAN_FLEXCAN tristate "Support for Freescale FLEXCAN based chips" depends on ARM || PPC ---help--- Say Y here if you want to support for Freescale FlexCAN. config CAN_GRCAN tristate "Aeroflex Gaisler GRCAN and GRHCAN CAN devices" depends on OF && HAS_DMA ---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 tristate "Janz VMOD-ICAN3 Intelligent CAN controller" depends on MFD_JANZ_CMODIO ---help--- Driver for Janz VMOD-ICAN3 Intelligent CAN controller module, which connects to a MODULbus carrier board. This driver can also be built as a module. If so, the module will be called janz-ican3.ko. config CAN_SUN4I tristate "Allwinner A10 CAN controller" depends on MACH_SUN4I || MACH_SUN7I || COMPILE_TEST ---help--- Say Y here if you want to use CAN controller found on Allwinner A10/A20 SoCs. To compile this driver as a module, choose M here: the module will be called sun4i_can. config CAN_TI_HECC depends on ARM tristate "TI High End CAN Controller" ---help--- Driver for TI HECC (High End CAN Controller) module found on many TI devices. The device specifications are available from www.ti.com config CAN_XILINXCAN tristate "Xilinx CAN" depends on ARCH_ZYNQ || ARM64 || MICROBLAZE || COMPILE_TEST depends on COMMON_CLK && HAS_IOMEM ---help--- Xilinx CAN driver. This driver supports both soft AXI CAN IP and Zynq CANPS IP. config PCH_CAN tristate "Intel EG20T PCH CAN controller" depends on PCI && (X86_32 || COMPILE_TEST) ---help--- This driver is for PCH CAN of Topcliff (Intel EG20T PCH) which is an IOH for x86 embedded processor (Intel Atom E6xx series). This driver can access CAN bus. source "drivers/net/can/c_can/Kconfig" source "drivers/net/can/cc770/Kconfig" source "drivers/net/can/ifi_canfd/Kconfig" source "drivers/net/can/m_can/Kconfig" source "drivers/net/can/mscan/Kconfig" source "drivers/net/can/peak_canfd/Kconfig" source "drivers/net/can/rcar/Kconfig" source "drivers/net/can/sja1000/Kconfig" source "drivers/net/can/softing/Kconfig" source "drivers/net/can/spi/Kconfig" source "drivers/net/can/usb/Kconfig" endif config CAN_DEBUG_DEVICES bool "CAN devices debugging messages" ---help--- Say Y here if you want the CAN device drivers to produce a bunch of debug messages to the system log. Select this if you are having a problem with CAN support and want to see more of what is going on. endmenu
