can: rcar_canfd: Add Renesas R-Car CAN FD driver 2016-06-17T13:39:47+00:00 Ramesh Shanmugasundaram ramesh.shanmugasundaram@bp.renesas.com 2016-06-17T08:20:55+00:00 dd3bd23eb438919aeeb73a7116642731ef8f73a8 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 and the driver can enable either or both of the channels. Driver uses Rx FIFOs (one per channel) for reception & Common FIFOs (one per channel) for transmission. Rx filter rules are configured to the minimum (one per channel) and it accepts Standard, Extended, Data & Remote Frame combinations. Note: There are few documentation errors in R-Car Gen3 Hardware User Manual v0.5E with respect to CAN FD controller. They are listed below: 1. CAN FD interrupt numbers 29 & 30 are listed as per channel interrupts. However, they are common to both channels (i.e.) they are global and channel interrupts respectively. 2. CANFD clock is derived from PLL1. This is not documented. 3. CANFD clock is further divided by (1/2) within the CAN FD controller. This is not documented. 4. The minimum value of NTSEG1 in RSCFDnCFDCmNCFG register is 2 Tq. It is specified 4 Tq in the manual. 5. The maximum number of message RAM area the controller can use is 3584 bytes. It is specified 10752 bytes in the manual.

For TX, only one dedicated tx buffer is used for sending data. For RX, RXFIFO 0 is used for receiving data to avoid overflow. Rx FIFO 1 and Rx Buffers are not used currently, as well as Tx Event FIFO. Due to the message ram can be shared by multi m_can instances and the fifo element is configurable which is SoC dependant, the design is to parse the message ram related configuration data from device tree rather than hardcode define it in driver which can make the message ram sharing fully transparent to M_CAN controller driver, then we can gain better driver maintainability and future features upgrade. M_CAN also supports CANFD protocol features like data payload up to 64 bytes and bitrate switch at runtime, however, this patch still does not add the support for these features.
