2009-08-14can: fix oops caused by wrong rtnl newlink usageOliver Hartkopp1-0/+7
For 'real' hardware CAN devices the netlink interface is used to set CAN specific communication parameters. Real CAN hardware can not be created with the ip tool ... The invocation of 'ip link add type can' lead to an oops as the standard rtnl newlink function was called: http://bugzilla.kernel.org/show_bug.cgi?id=13954 This patch adds a private newlink function for the CAN device driver interface that unconditionally returns -EOPNOTSUPP.

2009-07-20can: switch carrier on if device was stopped while in bus-off stateWolfgang Grandegger1-0/+4
This patch fixes a problem when a device is stopped while in the bus-off state. Then the carrier remains off forever. Signed-off-by: Kurt Van Dijck <kurt.van.dijck@skynet.be> Signed-off-by: Wolfgang Grandegger <wg@grandegger.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-06-10can: sja1000_of_platform: fix build problems with printk formatWolfgang Grandegger1-4/+6
According to "Documentation/printk-formats.txt", if the type is dependent on a config option for its size, like resource_size_t, we should use a format specifier of its largest possible type and explicitly cast to it.

2009-06-01can: sja1000: generic OF platform bus driverWolfgang Grandegger3-0/+243
This patch adds a generic driver for SJA1000 chips on the OpenFirmware platform bus found on embedded PowerPC systems. You need a SJA1000 node definition in your flattened device tree source (DTS) file similar to: can@3,100 { compatible = "nxp,sja1000"; reg = <3 0x100 0x80>; interrupts = <2 0>; interrupt-parent = <&mpic>; nxp,external-clock-frequency = <16000000>; }; See also Documentation/powerpc/dts-bindings/can/sja1000.txt.

2009-06-01can: sja1000: stop misusing member base_addr of struct net_deviceWolfgang Grandegger5-98/+95
As discussed on the netdev mailing list, the member "base_addr" of "struct net_device" should not be (mis)used to store the virtual address to the SJA1000 register area. According to David Miller, it's only use is to allow ISA and similar primitive bus devices to have their I/O ports changed via ifconfig. The virtual address is now stored in the private data structure of the SJA1000 device and the callback functions use "struct sja1000_priv" instead of the unneeded "struct net_device".

2009-05-19can: CAN Network device driver and Netlink interfaceWolfgang Grandegger3-0/+685
The CAN network device driver interface provides a generic interface to setup, configure and monitor CAN network devices. It exports a set of common data structures and functions, which all real CAN network device drivers should use. Please have a look to the SJA1000 or MSCAN driver to understand how to use them. The name of the module is can-dev.ko. Furthermore, it adds a Netlink interface allowing to configure the CAN device using the program "ip" from the iproute2 utility suite.
