Softing Gmbh CAN cards come with 1 or 2 physical buses. Those cards typically use Dual Port RAM to communicate with the host CPU. The interface is then identical for PCI and PCMCIA cards. This driver operates on a platform device, which has been created by softing_cs or softing_pci driver. Warning: The API of the card does not allow fine control per bus, but controls the 2 buses on the card together. As such, some actions (start/stop/busoff recovery) on 1 bus must bring down the other bus too temporarily. config CAN_SOFTING_CS tristate "Softing Gmbh CAN pcmcia cards" depends on PCMCIA depends on CAN_SOFTING help Support for PCMCIA cards from Softing Gmbh & some cards from Vector Gmbh. You need firmware for these, which you can get at https://github.com/linux-can/can-firmware This version of the driver is written against firmware version 4.6 (softing-fw-4.6-binaries.tar.gz) In order to use the card as CAN device, you need the Softing generic support too.
