This fix avoids a deadlock if an interrupt occurs
during consecutive port operations on ISA cards
utilising indirect access via address and data
port.
Tested on a B&R ISA card.

On slow systems and high CAN bitrates, the error message
"can_put_echo_skb: BUG! echo_skb is occupied!" did show up because
can_put_echo_skb() was called after starting the transfer.

This driver works with both, static platform data and device tree
bindings. It has been tested on a TQM855L board with two AN82527
CAN controllers on the local bus.

can: cc770: add legacy ISA bus driver for the CC770 and AN825272011-12-01T18:09:31+00:00Wolfgang Grandeggerwg@grandegger.com2011-11-30T23:41:19+00:00urn:sha1:edd2c26ffb7742bf0d3bd324694d220281844a01
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 [DSC])
bcr: Bus configuration register (default=0x40 [CBY])
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
