5 Add support for the Atmel WILC1000 802.11 b/g/n SoC.
6 This provides Wi-FI over an SDIO or SPI interface, and
7 is usually found in IoT devices.
9 This module only support IEEE 802.11n WiFi.
12 tristate "Atmel WILC1000 SDIO (WiFi only)"
13 depends on CFG80211 && INET && MMC
16 This module adds support for the SDIO interface of adapters using
17 WILC1000 chipset. The Atmel WILC1000 SDIO is a full speed interface.
18 It meets SDIO card specification version 2.0. The interface supports
19 the 1-bit/4-bit SD transfer mode at the clock range of 0-50 MHz.
20 The host can use this interface to read and write from any register
21 within the chip as well as configure the WILC1000 for data DMA.
22 To use this interface, pin9 (SDIO_SPI_CFG) must be grounded. Select
23 this if your platform is using the SDIO bus.
26 tristate "Atmel WILC1000 SPI (WiFi only)"
27 depends on CFG80211 && INET && SPI
32 This module adds support for the SPI interface of adapters using
33 WILC1000 chipset. The Atmel WILC1000 has a Serial Peripheral
34 Interface (SPI) that operates as a SPI slave. This SPI interface can
35 be used for control and for serial I/O of 802.11 data. The SPI is a
36 full-duplex slave synchronous serial interface that is available
37 immediately following reset when pin 9 (SDIO_SPI_CFG) is tied to
38 VDDIO. Select this if your platform is using the SPI bus.
40 config WILC1000_HW_OOB_INTR
41 bool "WILC1000 out of band interrupt"
42 depends on WILC1000_SDIO
44 This option enables out-of-band interrupt support for the WILC1000
45 chipset. This OOB interrupt is intended to provide a faster interrupt
46 mechanism for SDIO host controllers that don't support SDIO interrupt.
47 Select this option If the SDIO host controller in your platform
48 doesn't support SDIO time division interrupt.
