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>
