Hello,
I switched the discussion to the new Linux-CAN mailing list.

As I see it, the D_CAN is a more advanced variant of the C_CAN
controller. See also:
http://www.semiconductors.bosch.de/en/ipmodules/can/canipmodules/c_can/c_can.asp
http://www.semiconductors.bosch.de/en/ipmodules/can/canipmodules/d_can/d_can.asp
Patches to add D_CAN support to the Linux-CAN C_CAN driver have been
posted recently for mainline inclusion and are currently reviewed.

No, nothing apart from the fact that both are CAN controllers. The
mcp2515 is connected via SPI bus and from another company.

Hardware-wise, yes.

Right. On the AM335x, the D_CAN controller is integrated into the SOC.
There is no SPI involved.

Hope it's useful.

Is there a possibility of pushing my driver into 3.5 kernel?

Yes, I think we should push it forward, even if the C_CAN part remains
untested for the moment. IIRC, the patch series is already in a good
shape. I personally do also not have a board with a C_CAN controller at
hand. Marc, what is your opinion?
Wolfgang.

I don't have any of the *_CAN hardware. But the driver looks quite good.
I'm quite busy at the moment, but currently we've the merge window. I'll
do a review now, anyway. Wolfgang can I have your Acked-by?

I just tried to compile check the patches but they do not apply properly
:(. AnilKumar, for what kernel tree are the patches you posted? They
should be against David Miller's net-next tree?
Wolfgang.

We have a BeagleBone in the PTX Lab, with an AM3359, which has the CAN
port on the extension header. Does that help?

Sure \o/, if our soldermaster can attach it to our CAN network.

I'll ask him when he's in the office :-)
However, you might need to port mainline linux to it first...

I have generated the patch series with "v3.4-rc6". I can quickly spin patches with

That would be nice. We need the patches against:
