| 6 | Support for CAN cards from Softing Gmbh & some cards |
| 7 | from Vector Gmbh. |
| 8 | Softing Gmbh CAN cards come with 1 or 2 physical buses. |
| 9 | Those cards typically use Dual Port RAM to communicate |
| 10 | with the host CPU. The interface is then identical for PCI |
| 11 | and PCMCIA cards. This driver operates on a platform device, |
| 12 | which has been created by softing_cs or softing_pci driver. |
| 13 | Warning: |
| 14 | The API of the card does not allow fine control per bus, but |
| 15 | controls the 2 buses on the card together. |
| 16 | As such, some actions (start/stop/busoff recovery) on 1 bus |
| 17 | must bring down the other bus too temporarily. |

| 26 | You need firmware for these, which you can get at |
| 27 | https://github.com/linux-can/can-firmware |
| 28 | This version of the driver is written against |
| 29 | firmware version 4.6 (softing-fw-4.6-binaries.tar.gz) |
| 30 | In order to use the card as CAN device, you need the Softing generic |
| 31 | support too. |
