How do I > setup the irq? a) move the things from the .board_specific function to your boardfile and call them prior to registering the mcp2515 at the spi framework b) wait until someone implements the .board_specific hook in the driver c) implement it yourself Oh...wait...someone just did b) (not tested so far) http://git.pengutronix.de/?p=mkl/linux-2.6.git;a=shortlog;h=refs/heads/can/mcp251x-async-boardsetup cheers, Marc -- Pengutronix e.K. | Marc Kleine-Budde | Industrial Linux Solutions | Phone: +49-231-2826-924 | Vertretung West/Dortmund | Fax: +49-5121-206917-5555 | Amtsgericht Hildesheim, HRA 2686 | http://www.pengutronix.de |
