config CAN_SOFTING
tristate "Softing Gmbh CAN generic support"
depends on CAN_DEV
---help---
Support for CAN cards from Softing Gmbh & some cards
from Vector Gmbh.
Softing Gmbh CAN cards come with 1 or 2 physical busses.
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 busses on the card together.
As such, some actions (start/stop/busoff recovery) on 1 bus
must bring down the other bus too temporarily.
