mcp251x driver Intel platform

[Mario Schuknecht <mario.schuknecht@xxxxxxxxxxxxxxx>]

Hello,

I have to connect the MCP2515 CAN controller with SPI interface to an
Intel Atom processor.
On an ARM platform the driver mcp251x is configured via device tree.
However, the Intel Atom platform has no device tree.

My question:
How can the Linux driver mcp251x (driver/net/can/spi/mcp251x.c) be
configured on an Intel Atom platform (SPI Bus, Chip Select)?

I'm grateful for any information.

With kind regards
