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.

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.
