| Add support for the Atmel WILC1000 802.11 b/g/n SoC. |
| This provides Wi-FI over an SDIO or SPI interface, and |
| is usually found in IoT devices. |
| |
| This module only support IEEE 802.11n WiFi. |

| 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. |

| help |
| 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. |

| help |
| This option enables out-of-band interrupt support for the WILC1000 |
| chipset. This OOB interrupt is intended to provide a faster interrupt |
| mechanism for SDIO host controllers that don't support SDIO interrupt. |
| Select this option If the SDIO host controller in your platform |
| doesn't support SDIO time division interrupt. |
