can: add support for CAN interface cards based on the PLX90xx PCI bridge
This driver is for CAN interface cards based on the PLX90xx PCI bridge. Driver supports now: - Adlink PCI-7841/cPCI-7841 card (http://www.adlinktech.com/) - Adlink PCI-7841/cPCI-7841 SE card - Marathon CAN-bus-PCI card (http://www.marathon.ru/) - TEWS TECHNOLOGIES TPMC810 card (http://www.tews.com/) Changes since v1: - Added some defines for static inline int plx_pci_check_sja1000(...) - static struct pci_device_id plx_pci_tbl[] replaced by static DEFINE_PCI_DEVICE_TABLE(plx_pci_tbl) - Typo fixed Signed-off-by: Pavel Cheblakov <P.B.Cheblakov@inp.nsk.su> Acked-by: Wolfgang Grandegger <wg@grandegger.com> Signed-off-by: David S. Miller <davem@davemloft.net>
