This patch removes the Kconfig symbol HAVE_CAN_FLEXCAN from arch/{arm,powerpc}
and allowing compilation unconditionally on all arm and powerpc platforms.
This brings a bigger compile time coverage and removes the following dependency
warning found by Arnd Bergmann:
warning: (SOC_IMX28 && SOC_IMX25 && SOC_IMX35 && IMX_HAVE_PLATFORM_FLEXCAN &&
SOC_IMX53 && SOC_IMX6Q) selects HAVE_CAN_FLEXCAN
which has unmet direct dependencies (NET && CAN && 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_SLCAN

tristate "Serial / USB serial CAN Adaptors (slcan)"

|
|
---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

|

support. This is the standard library for CAN drivers.

If unsure, say Y.

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.

---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.

endian syntheses of the cores would need some modifications on
|

the hardware level to work.
