can: export a safe netdev_priv wrapper for candev

2013-01-26T15:58:59Z

In net_device notifier calls, it was impossible to determine if a CAN device is based on candev in a safe way. This patch adds such test in order to access candev storage from within those notifiers.

can: add tx/rx LED trigger support

2013-01-26T15:58:59Z

This patch implements the functions to add two LED triggers, named -tx and -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 Cc: Marc Kleine-Budde Signed-off-by: Fabio Baltieri Acked-by: Oliver Hartkopp Signed-off-by: Marc Kleine-Budde

can: mark bittiming_const pointer in struct can_priv as const

2012-07-20T10:31:05Z

This patch marks the bittiming_const pointer as in the struct can_pric as "const". This allows us to mark the struct can_bittiming_const in the CAN drivers as "const", too. Signed-off-by: Marc Kleine-Budde

candev: add/update helpers for CAN FD

2012-06-19T19:40:14Z

- update sanity checks - add DLC to length conversion helpers - can_dlc2len() - get data length from can_dlc with sanitized can_dlc - can_len2dlc() - map the sanitized data length to an appropriate DLC Signed-off-by: Oliver Hartkopp Signed-off-by: Marc Kleine-Budde

can: dev: let can_get_echo_skb() return dlc of CAN frame

2012-02-03T00:21:25Z

can_get_echo_skb() is usually called in the TX complete handler. The stats->tx_packets and stats->tx_bytes should be updated there, too. This patch simplifies to figure out the size of the sent CAN frame. Signed-off-by: Marc Kleine-Budde

can: remove references to berlios mailinglist

2011-10-17T23:22:46Z

The BerliOS project, which currently hosts our mailinglist, will close with the end of the year. Now take the chance and remove all occurrences of the mailinglist address from the source files. Signed-off-by: Marc Kleine-Budde Signed-off-by: David S. Miller

Fix some #includes in CAN drivers (rebased for net-next-2.6)

2010-04-13T10:32:42Z

In the current implementation, CAN drivers need to #include _before_ they #include , which is both ugly and unnecessary. Fix this by including in and remove the #include lines from drivers. Signed-off-by: Hans J. Koch Signed-off-by: David S. Miller

can: netlink support for bus-error reporting and counters

2010-02-26T09:48:49Z

This patch makes the bus-error reporting configurable and allows to retrieve the CAN TX and RX bus error counters via netlink interface. I have added support for the SJA1000. The TX and RX bus error counters are also copied to the data fields 6..7 of error messages when state changes are reported. Signed-off-by: Wolfgang Grandegger Signed-off-by: David S. Miller

can: Proper ctrlmode handling for CAN devices

2010-01-15T09:39:17Z

This patch adds error checking of ctrlmode values for CAN devices. As an example all availabe bits are implemented in the mcp251x driver. Signed-off-by: Christian Pellegrin Acked-by: Wolfgang Grandegger Signed-off-by: David S. Miller

can: Unify droping of invalid tx skbs and netdev stats

2010-01-12T10:00:46Z

To prevent the CAN drivers to operate on invalid socketbuffers the skbs are now checked and silently dropped at the xmit-function consistently. Also the netdev stats are consistently using the CAN data length code (dlc) for [rx|tx]_bytes now. Signed-off-by: Oliver Hartkopp Acked-by: Wolfgang Grandegger Signed-off-by: David S. Miller
