- 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.
- config WILC1000_HW_OOB_INTR
- bool "WILC1000 out of band interrupt"
- depends on WILC1000_SDIO
- 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.
