Message-ID <[email protected]>
'num-cs' property is a single integer, thus the binding should not set
maxItems.  This could be replaced with proper min/max constraints for
values, except that hardware (as expressed in driver) supports only one
native chipselect, thus constraint of "const:1" would make the property
implied by the compatible.  spi-controller.yaml schema already defines
this property, so its presence here is redundant.
