2017-02-06can: rx-offload: Add support for HW fifo based irq offloadingDavid Jander1-1/+2
Some CAN controllers have a usable FIFO already but can still benefit from off-loading the CAN controller FIFO. The CAN frames of the FIFO are read and put into a skb queue during interrupt and then transmitted in a NAPI context.

2016-06-17can: rcar_canfd: Add Renesas R-Car CAN FD driverRamesh Shanmugasundaram1-0/+1
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.

2014-08-18can: m_can: add Bosch M_CAN controller supportDong Aisheng1-0/+1
The patch adds the basic CAN TX/RX function support for Bosch M_CAN controller. 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.

2013-01-26can: add tx/rx LED trigger supportFabio Baltieri1-0/+2
This patch implements the functions to add two LED triggers, named <ifname>-tx and <ifname>-rx, to a canbus device driver. Triggers are called from specific handlers by each CAN device driver and can be disabled altogether with a Kconfig option. The implementation keeps the LED on when the interface is UP and blinks the LED on network activity at a configurable rate. This only supports can-dev based drivers, as it uses some support field in the can_priv structure. Supported drivers should call devm_can_led_init() and can_led_event() as needed. Cleanup is handled automatically by devres, so no *_exit function is needed. Supported events are: - CAN_LED_EVENT_OPEN: turn on tx/rx LEDs - CAN_LED_EVENT_STOP: turn off tx/rx LEDs - CAN_LED_EVENT_TX: trigger tx LED blink - CAN_LED_EVENT_RX: trigger tx LED blink Cc: Wolfgang Grandegger <wg@grandegger.com> Cc: Marc Kleine-Budde <mkl@pengutronix.de> Signed-off-by: Fabio Baltieri <fabio.baltieri@gmail.com> Acked-by: Oliver Hartkopp <socketcan@hartkopp.net> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>

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 patch adds support for serial/USB-serial CAN adapters implementing the LAWICEL ASCII protocol for CAN frame transport over serial lines. The driver implements the SLCAN line discipline and is heavily based on the slip.c driver. Therefore the code style remains similar to slip.c to be able to apply changes of the SLIP driver to the SLCAN driver easily. For more details see the slcan Kconfig entry.
