I am trying to setup mcp251x on UP2. 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 help ??

I hope, You have resolved your problem,.
Anyway, check first your devicetree, that all pincontrol are declared and in correct state.
For instance google "mcp2515 linux devicetree"
