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. 24 25config WILC1000_SPI 26 tristate "Atmel WILC1000 SPI (WiFi only)" 27 depends on CFG80211 && INET && SPI 28 select WILC1000 29 select CRC7 30 select CRC_ITU_T 31 help 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. 39 40config WILC1000_HW_OOB_INTR 41 bool "WILC1000 out of band interrupt" 42 depends on WILC1000_SDIO 43 help 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.
