+	  This module adds support for the SDIO interface of adapters using
+	  WILC1000 chipset. The Atmel WILC1000 SDIO is a full speed interface.
+	  It meets SDIO card specification version 2.0. The interface supports
+	  the 1-bit/4-bit SD transfer mode at the clock range of 0-50 MHz.
+	  The host can use this interface to read and write from any register
+	  within the chip as well as configure the WILC1000 for data DMA.
+	  To use this interface, pin9 (SDIO_SPI_CFG) must be grounded. Select
+	  this if your platform is using the SDIO bus.

+	  This module adds support for the SPI interface of adapters using
+	  WILC1000 chipset. The Atmel WILC1000 has a Serial Peripheral
+	  Interface (SPI) that operates as a SPI slave. This SPI interface can
+	  be used for control and for serial I/O of 802.11 data. The SPI is a
+	  full-duplex slave synchronous serial interface that is available
+	  immediately following reset when pin 9 (SDIO_SPI_CFG) is tied to
+	  VDDIO. Select this if your platform is using the SPI bus.
