can: mark bittiming_const pointer in struct can_priv as const

2012-07-20T10:31:05+00:00

This patch marks the bittiming_const pointer as in the struct can_pric as
"const". This allows us to mark the struct can_bittiming_const in the CAN
drivers as "const", too.

can: cc770: fix sparse warning for cc770_interrupt

2012-07-02T09:07:24+00:00

Make cc770_interrupt static to fix the following sparse warning:
drivers/net/can/cc770/cc770.c:699:13: warning: symbol
'cc770_interrupt' was not declared. Should it be static?

can: cc770: Fix likely misuse of | for &

2012-06-03T16:59:21+00:00

Using | with a constant is always true.
Likely this should have be &.

can: cc770: Fix indirect access deadlock on ISA cards

2012-02-02T23:25:06+00:00

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.

can: cc770: store echo skb before starting the transfer

2012-02-02T23:24:59+00:00

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.

can: cc770: add platform bus driver for the CC770 and AN82527

2011-12-01T18:09:31+00:00

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 AN82527

2011-12-01T18:09:31+00:00

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
