can: c_can: don't indicate triple sampling support for D_CAN

2017-11-15T09:09:19+00:00

commit fb5f0b3ef69b95e665e4bbe8a3de7201f09f1071 upstream. The D_CAN controller doesn't provide a triple sampling mode, so don't set the CAN_CTRLMODE_3_SAMPLES flag in ctrlmode_supported. Currently enabling triple sampling is a no-op. Signed-off-by: Richard Schütz Signed-off-by: Marc Kleine-Budde Signed-off-by: Greg Kroah-Hartman

can: ifi: Fix transmitter delay calculation

2017-11-15T09:09:19+00:00

commit 4f7116757b4bd99e4ef2636c7d957a6d63035d11 upstream. The CANFD transmitter delay calculation formula was updated in the latest software drop from IFI and improves the behavior of the IFI CANFD core during bitrate switching. Use the new formula to improve stability of the CANFD operation. Signed-off-by: Marek Vasut Cc: Markus Marb Signed-off-by: Marc Kleine-Budde Signed-off-by: Greg Kroah-Hartman

can: peak: Add support for new PCIe/M2 CAN FD interfaces

2017-11-15T09:09:19+00:00

commit 4cbdd0ee67191481ec57ceed94febdfef95c9f25 upstream. This adds support for the following PEAK-System CAN FD interfaces: PCAN-cPCIe FD CAN FD Interface for cPCI Serial (2 or 4 channels) PCAN-PCIe/104-Express CAN FD Interface for PCIe/104-Express (1, 2 or 4 ch.) PCAN-miniPCIe FD CAN FD Interface for PCIe Mini (1, 2 or 4 channels) PCAN-PCIe FD OEM CAN FD Interface for PCIe OEM version (1, 2 or 4 ch.) PCAN-M.2 CAN FD Interface for M.2 (1 or 2 channels) Like the PCAN-PCIe FD interface, all of these boards run the same IP Core that is able to handle CAN FD (see also http://www.peak-system.com).

can: sun4i: handle overrun in RX FIFO

2017-11-15T09:09:18+00:00

commit 4dcf924c2eda0c47a5c53b7703e3dc65ddaa8920 upstream. SUN4Is CAN IP has a 64 byte deep FIFO buffer. If the buffer is not drained fast enough (overrun) it's getting mangled. Already received frames are dropped - the data can't be restored. Signed-off-by: Gerhard Bertelsmann Signed-off-by: Marc Kleine-Budde Signed-off-by: Greg Kroah-Hartman

can: kvaser_usb: Ignore CMD_FLUSH_QUEUE_REPLY messages

2017-11-02T08:54:49+00:00

commit e1d2d1329a5722dbecc9c278303fcc4aa01f8790 upstream. To avoid kernel warning "Unhandled message (68)", ignore the CMD_FLUSH_QUEUE_REPLY message for now. As of Leaf v2 firmware version v4.1.844 (2017-02-15), flush tx queue is synchronous. There is a capability bit indicating whether flushing tx queue is synchronous or asynchronous. A proper solution would be to query the device for capabilities. If the synchronous tx flush capability bit is set, we should wait for CMD_FLUSH_QUEUE_REPLY message, while flushing the tx queue.

can: kvaser_usb: Correct return value in printout

2017-11-02T08:54:49+00:00

commit 8f65a923e6b628e187d5e791cf49393dd5e8c2f9 upstream. If the return value from kvaser_usb_send_simple_msg() was non-zero, the return value from kvaser_usb_flush_queue() was printed in the kernel warning.
