The interface is then identical for PCI 1103fd3cf5SKurt Van Dijck and PCMCIA cards. This driver operates on a platform device, 1203fd3cf5SKurt Van Dijck which has been created by softing_cs or softing_pci driver. 1303fd3cf5SKurt Van Dijck Warning: 1403fd3cf5SKurt Van Dijck The API of the card does not allow fine control per bus, but 1588bfb9a7SMarc Kleine-Budde controls the 2 buses on the card together. 1603fd3cf5SKurt Van Dijck As such, some actions (start/stop/busoff recovery) on 1 bus 1703fd3cf5SKurt Van Dijck must bring down the other bus too temporarily. 180a0b7a5fSKurt Van Dijck 190a0b7a5fSKurt Van Dijckconfig CAN_SOFTING_CS 200a0b7a5fSKurt Van Dijck tristate "Softing Gmbh CAN pcmcia cards" 210a0b7a5fSKurt Van Dijck depends on PCMCIA 22ddfdb508SKurt Van Dijck depends on CAN_SOFTING 23a7f7f624SMasahiro Yamada help 240a0b7a5fSKurt Van Dijck Support for PCMCIA cards from Softing Gmbh & some cards 250a0b7a5fSKurt Van Dijck from Vector Gmbh. 260a0b7a5fSKurt Van Dijck You need firmware for these, which you can get at 27f61e7bfaSDiego Elio Pettenò https://github.com/linux-can/can-firmware 280a0b7a5fSKurt Van Dijck This version of the driver is written against 290a0b7a5fSKurt Van Dijck firmware version 4.6 (softing-fw-4.6-binaries.tar.gz) 300a0b7a5fSKurt Van Dijck In order to use the card as CAN device, you need the Softing generic 310a0b7a5fSKurt Van Dijck support too. 32
