This patch adds a generic driver for SJA1000 chips on the OpenFirmware
platform bus found on embedded PowerPC systems. You need a SJA1000 node
definition in your flattened device tree source (DTS) file similar to:
can@3,100 {
compatible = "nxp,sja1000";
reg = <3 0x100 0x80>;
interrupts = <2 0>;
interrupt-parent = <&mpic>;
nxp,external-clock-frequency = <16000000>;
};

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.

|

---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.

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,
