The wilc1000 chips can be connected via SPI or SDIO. This document
describes the binding to connect wilc devices.

description: Used by wilc1000-spi to determine the GPIO line
connected to the ENABLE line. If specified, reset-gpios
must be specified as well as otherwise the driver cannot
ensure the timing required between asserting ENABLE
and deasserting RESET. This should be declared as an
active-high signal.
