Hi again,

here are some updates:

https://github.com/btolfa/sunxi-can-driver

It it's sja1000 compatible, it should work out of the box with the
existing sja1000 device tree binding.

the Allwinner CAN IP is very similar but not exactly a SJA1000, e g. the
registers differ and some are 32 bit wide and not 8 bit.
So the question is: change the sja1000 and the platform file for 
"quirks"
or write a new independent one ?
Which way do you prefer or better: which driver will be accepted for 
mainline ?

Marc

Regards

Gerd
