    Mcp251x CAN driver errors.

      I am trying to setup mcp251x on Intel Atom. When I run  dmesg | grep mcp  , this is what I get:

       

      [ 3394.625374] device: 'spi1.0': device_add

      [ 3394.625384] bus: 'spi': add device spi1.0

      [ 3394.625460] PM: Adding info for spi:spi1.0

      [ 3394.625478] bus: 'spi': driver_probe_device: matched device spi1.0 with driver mcp251x

      [ 3394.625480] bus: 'spi': really_probe: probing driver mcp251x with device spi1.0

      [ 3394.625487] mcp251x spi1.0: no default pinctrl state

      [ 3394.625494] devices_kset: Moving spi1.0 to end of list

      [ 3394.655161] mcp251x spi1.0: Cannot initialize MCP2515. Wrong wiring?

      [ 3394.662335] mcp251x spi1.0: Probe failed, err=19

      [ 3394.667521] mcp251x: probe of spi1.0 rejects match -19

       

      What does the error "no default pinctrl state" refer to ?

      Any ideas ??
