can: sja1000: legacy SJA1000 ISA bus driver
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
