* can: Enable -D__CHECK_ENDIAN__ for sparse by defaultMarc Kleine-Budde2014-12-07

* can: m_can: add Bosch M_CAN controller supportDong Aisheng2014-08-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* can: add tx/rx LED trigger supportFabio Baltieri2013-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* can: c_can: Added support for Bosch C_CAN controllerBhupesh Sharma2011-02-14
| | | | | | | | | | | | | | | | | | | | 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.

* can: add slcan driver for serial/USB-serial CAN adaptersOliver Hartkopp2010-12-08
| | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | The CAN network device driver interface provides a generic interface to setup, configure and monitor CAN network devices. It exports a set of common data structures and functions, which all real CAN network device drivers should use. Please have a look to the SJA1000 or MSCAN driver to understand how to use them. The name of the module is can-dev.ko. Furthermore, it adds a Netlink interface allowing to configure the CAN device using the program "ip" from the iproute2 utility suite.
