config WILC1000
tristate
help
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.
config WILC1000_SDIO
tristate "Atmel WILC1000 SDIO (WiFi only)"
depends on CFG80211 && INET && MMC
select WILC1000
help
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.
config WILC1000_SPI
tristate "Atmel WILC1000 SPI (WiFi only)"
depends on CFG80211 && INET && SPI
select WILC1000
select CRC7
select CRC_ITU_T
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.
