This patch adds the support for D_CAN controller driver to the existing C_CAN driver. Bosch D_CAN controller is a full-CAN implementation which is compliant to CAN protocol version 2.0 part A and B. Bosch D_CAN user manual can be obtained from: http://www.semiconductors.bosch.de/media/en/pdf/ ipmodules_1/can/d_can_users_manual_111.pdf A new array is added for accessing the d_can registers, according to d_can controller register space. Current D_CAN implementation has following limitations, this is done to avoid large changes to the C_CAN driver. 1. Message objects are limited to 32, 16 for RX and 16 for TX. C_CAN IP supports upto 32 message objects but in case of D_CAN we can configure upto 128 message objects. 2. Using two 16bit reads/writes for accessing the 32bit D_CAN registers. 3. These patches have been tested on little endian machine, there might be some hidden endian-related issues due to the nature of the accesses (32-bit registers accessed as 2 16-bit registers). However, I do not have a big-endian D_CAN implementation to confirm. Signed-off-by: AnilKumar Ch <anilkumar@ti.com> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>

This driver adds support for the C_CAN/D_CAN chips connected
|
|
to the "platform bus" (Linux abstraction for directly to the
|
|
processor attached devices) which can be found on various
|
|
boards from ST Microelectronics (http://www.st.com) like the
|
|
SPEAr1310 and SPEAr320 evaluation boards & TI (www.ti.com)
|

boards like am335x, dm814x, dm813x and dm811x.
