The member "clock" of struct "sja1000_platform_data" is documented as
"CAN bus oscillator frequency in Hz" but it's actually used as the CAN
clock frequency, which is half of it. To avoid further confusion, this
patch fixes it by renaming the member to "osc_freq". That way, also
non mainline users will notice the change. The platform code for the
relevant boards is updated accordingly. Furthermore, pre-defined
values are now used for the members "ocr" and "cdr".

Chip model can now be selected directly by matching the modalias name
(instead of filling the .model field in platform_data), and allows the
module to be auto-loaded. Previous behaviour is of course still supported.
Convert the two in-tree users to this feature (icontrol & zeus).
Tested on an Zeus platform (mcp2515).

CAN module on AM3517 requires programming of IO expander as part
of init sequence - to enable CAN PHY. Added platform specific
callback to handle phy control(switch on /off).

TI HECC (High End CAN Controller) module is found on many TI devices. It
has 32 hardware mailboxes with full implementation of CAN protocol 2.0B
with bus speeds up to 1Mbps. Specifications of the module are available

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>;
};

This driver adds support for the SJA1000 chips connected to the
"platform bus", which can be found on various embedded systems.
