Details

sck-pin

int

 
The SCK pin to use.

For pins P0.0 through P0.31, use the pin number. For example,
to use P0.16 for SCK, set:

    sck-pin = <16>;

For pins P1.0 through P1.31, add 32 to the pin number. For
example, to use P1.2 for SCK, set:

    sck-pin = <34>;  /* 32 + 2 */

This property is required.

io-pins

array

 
Pin numbers associated with IO0 through IO3 signals.

Examples:

    io-pins = <io0-pin io1-pin>; // two pins

    io-pins = <io0-pin io1-pin io2-pin io3-pin>; // four pins

Either two or four pins must be configured using this property
as shown above. The pin numbering scheme is the same as the
sck-pin property's.

This property is required.

csn-pins

array

 
Chip select signal pin number. Exactly one pin should be
given. The pin numbering scheme is the same as the
sck-pin property's.

This property is required.
