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

properties:
  compatible:
    const: microchip,wilc1000

  reg: true

  interrupts:
    maxItems: 1

  clocks:
    description: phandle to the clock connected on rtc clock line.
    maxItems: 1

  clock-names:
    const: rtc

  enable-gpios:
    maxItems: 1
    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.

  reset-gpios:
    maxItems: 1
    description: Used by wilc1000-spi to determine the GPIO line
      connected to the RESET line.  This should be declared as an
      active-low signal.
