Wolfgang Grandegger 2a6ba39ad6 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

menu "CAN Device Drivers"

config CAN_VCAN
tristate "Virtual Local CAN Interface (vcan)"
depends on CAN
default N
---help---
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.
config CAN_DEV
tristate "Platform CAN drivers with Netlink support"
depends on CAN
default Y
---help---
Enables the common framework for platform CAN drivers with Netlink
support. This is the standard library for CAN drivers.
If unsure, say Y.
config CAN_CALC_BITTIMING
bool "CAN bit-timing calculation"
depends on CAN_DEV
default Y
---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.

Driver for the SJA1000 CAN controllers from Philips or NXP

tristate "ISA Bus based legacy SJA1000 driver"
---help---
This driver adds legacy support for SJA1000 chips connected to
the ISA bus using I/O port, memory mapped or indirect access.
config CAN_SJA1000_PLATFORM
depends on CAN_SJA1000
tristate "Generic Platform Bus based SJA1000 driver"
---help---
This driver adds support for the SJA1000 chips connected to
the "platform bus" (Linux abstraction for directly to the
processor attached devices). Which can be found on various
boards from Phytec (http://www.phytec.de) like the PCM027,
PCM038.
config CAN_SJA1000_OF_PLATFORM
depends on CAN_SJA1000 && PPC_OF
tristate "Generic OF Platform Bus based SJA1000 driver"
---help---
This driver adds support for the SJA1000 chips connected to
the OpenFirmware "platform bus" found on embedded systems with
OpenFirmware bindings, e.g. if you have a PowerPC based system
you may want to enable this option.
config CAN_EMS_PCI
tristate "EMS CPC-PCI, CPC-PCIe and CPC-104P Card"
depends on PCI && CAN_SJA1000
---help---
This driver is for the one, two or four channel CPC-PCI,
CPC-PCIe and CPC-104P cards from EMS Dr. Thomas Wuensche
(http://www.ems-wuensche.de).
config CAN_KVASER_PCI
tristate "Kvaser PCIcanx and Kvaser PCIcan PCI Cards"

---help---
Say Y here if you want the CAN device drivers to produce a bunch of
debug messages to the system log. Select this if you are having
a problem with CAN support and want to see more of what is going
on.
