Instead of listing directly properties typical for SPI peripherals, reference the spi-peripheral-props.yaml schema. This allows using all properties typical for SPI-connected devices, even these which device bindings author did not tried yet. Remove the spi-* properties which now come via spi-peripheral-props.yaml schema, except for the cases when device schema adds some constraints like maximum frequency. While changing additionalProperties->unevaluatedProperties, put it in typical place, just before example DTS.

Without interrupt-names, the first interrupt listed must be the one
|
|
connected to the INT1 pin, the second (optional) interrupt listed must be
|
|
the one connected to the INT2 pin (if available). The type should be
|
|
IRQ_TYPE_EDGE_RISING.
|
|
|
|
BMC156 does not have an INT1 pin, therefore the first interrupt pin is
|
|
always treated as INT2.
