This patch adds support for the CAN FD controller found in Renesas R-Car
SoCs. The controller operates in CAN FD only mode by default.
CAN FD mode supports both Classical CAN & CAN FD frame formats. The
controller supports ISO 11898-1:2015 CAN FD format only.
This controller supports two channels
of various subsystem trees and (b) branches with driver code
submitted or planned for submission to maintainers into the development
branch of Simon Horman's renesas.git tree.
Today's version is based on renesas-devel-20160315-v4.5.
Included branches with driver code:
- sh-pfc-for-v4.7
