This patch adds support for legacy SJA1000 CAN controllers on the ISA
or PC-104 bus. The I/O port or memory address and the IRQ number must
be specified via module parameters:
insmod sja1000_isa.ko port=0x310,0x380 irq=7,11
for ISA devices using I/O ports or:
insmod sja1000_isa.ko mem=0xd1000,0xd1000 irq=7,11
for memory mapped ISA devices.
Indirect access via address and data port is supported as well:
insmod sja1000_isa.ko port=0x310,0x380 indirect=1 irq=7,11
Here is a full list of the supported module parameters:
port:I/O port number (array of ulong)
mem:I/O memory address (array of ulong)
indirect:Indirect access via address and data port (array of byte)
irq:IRQ number (array of int)
clk:External oscillator clock frequency (default=16000000 [16 MHz])
(array of int)
cdr:Clock divider register (default=0x48 [CDR_CBP | CDR_CLK_OFF])
(array of byte)
ocr:Output clock register (default=0x18 [OCR_TX0_PUSHPULL])
(array of byte)
Note: for clk, cdr, ocr, the first argument re-defines the default
for all other devices, e.g.:
insmod sja1000_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000
is equivalent to
insmod sja1000_isa.ko mem=0xd1000,0xd1000 irq=7,11 \
clk=24000000,24000000

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.

---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.
