Add support for mcan bit timing and control mode according to bosch mcan IP
version 3.3.0
The mcan version read from the Core Release field of CREL register would be
33. Accordingly the properties are to be set for mcan v3.3.0
BTW: do you have the v3.2 and v3.1 datasheets?
Unfortunately Bosch does not give access to older documents, so I tried
to concentrate all my downloaded versions of public available
information here:
https://github.com/hartkopp/M_CAN-User-Manual-History
PR's with updates are welcome ;-)
Best,
Oliver
ps. @Bosch Semiconductors - Read the README there! I would like to
remove my own collection.
