can: cc770: legacy CC770 ISA bus driver
This patch adds support for legacy Bosch CC770 and Intel AN82527 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 cc770_isa.ko port=0x310,0x380 irq=7,11
for ISA devices using I/O ports or:
insmod cc770_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 cc770_isa.ko port=0x310,0x380 indirect=1 irq=7,11
Furthermore, the following mode parameter can be defined:
clk: External oscillator clock frequency (default=16000000 [16 MHz])
cir: CPU interface register (default=0x40 [CPU_DSC])
ocr, Bus configuration register (default=0x00)
cor, Clockout register (default=0x00)
Note: for clk, cir, bcr and cor, the first argument re-defines the
default for all other devices, e.g.:
insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000
is equivalent to
insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000,24000000
