can: rockchip_canfd: add driver for Rockchip CAN-FD controller

2024-09-04T12:41:51Z

Add driver for the Rockchip CAN-FD controller. The IP core on the rk3568v2 SoC has 12 documented errata. Corrections for these errata will be added in the upcoming patches. Since several workarounds are required for the TX path, only add the base driver that only implements the RX path. Although the RX path implements CAN-FD support, it's not activated in ctrlmode_supported, as the IP core in the rk3568v2 has problems with receiving or sending certain CAN-FD frames.

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

2024-02-12T15:58:30Z

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

2023-10-06T10:54:33Z

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

2023-10-05T19:47:45Z

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().
