Bosch C_CAN controller is a full-CAN implementation which is compliant to CAN protocol version 2.0 part A and B. Bosch C_CAN user manual can be obtained from: http://www.semiconductors.bosch.de/media/en/pdf/ipmodules_1/c_can/users_manual_c_can.pdf This patch adds the support for this controller. The following are the design choices made while writing the controller driver: 1. Interface Register set IF1 has be used only in the current design. 2. Out of the 32 Message objects available, 16 are kept aside for RX purposes and the rest for TX purposes. 3. NAPI implementation is such that both the TX and RX paths function in polling mode.

This driver adds support for the C_CAN chips connected to

the "platform bus" (Linux abstraction for directly to the

boards from ST Microelectronics (http://www.st.com)
