can: esd: add support for esd GmbH PCIe/402 CAN interface family

2024-02-12T15:58:30+00:00

This patch adds support for the PCI based PCIe/402 CAN interface family from esd GmbH that is available with various form factors (https://esd.eu/en/products/402-series-can-interfaces). All boards utilize a FPGA based CAN controller solution developed by esd (esdACC). For more information on the esdACC see https://esd.eu/en/products/esdacc. This driver detects all available CAN interface board variants of the family but atm. operates the CAN-FD capable devices in Classic-CAN mode only! A later patch will introduce the CAN-FD functionality in this driver.

can: sun4i_can: Only show Kconfig if ARCH_SUNXI is set

2023-10-06T10:54:33+00:00

When adding the RISCV option I didn't gate it behind ARCH_SUNXI. As a result this option shows up with Allwinner support isn't enabled. Fix that by requiring ARCH_SUNXI to be set if RISCV is set.

can: at91_can: switch to rx-offload implementation

2023-10-05T19:47:45+00:00

The current at91_can driver uses NAPI to handle RX'ed CAN frames, the RX IRQ is disabled and a NAPI poll is scheduled. Then in at91_poll_rx() the RX'ed CAN frames are tried to read in order from the device. This approach has 2 drawbacks: - Under high system load it might take too long from the initial RX IRQ to the NAPI poll function to run. This causes RX buffer overflows. - The algorithm to read the CAN frames in order is not bullet proof and may fail under certain use cases/system loads. The rx-offload helper fixes these problems by reading the RX'ed CAN frames in the interrupt handler and adding it to a list sorted by RX timestamp. This list of RX'ed SKBs is then passed to the networking stack via NAPI. Convert the RX path to rx-offload, pass all CAN error frames with can_rx_offload_queue_timestamp().

The controllers present in the D1 are extremely similar to the R40 and require the same reset quirks, but An extra quirk is needed to support receiving packets. Signed-off-by: John Watts Link: https://lore.kernel.org/all/20230721221552.1973203-6-contact@jookia.org Signed-off-by: Marc Kleine-Budde

can: kvaser_pciefd: Remove SPI flash parameter read functionality

2023-06-22T07:44:29+00:00

Remove SPI flash parameter read functionality, since it's only used for reading the interface CAN controller count. This information is already read from a register, making the information redundant.

can: CAN_BXCAN should depend on ARCH_STM32

2023-05-15T20:24:47+00:00

The STMicroelectronics STM32 basic extended CAN Controller (bxCAN) is only present on STM32 SoCs. Hence drop the "|| OF" part from its dependency rule, to prevent asking the user about this driver when configuring a kernel without STM32 SoC support.
