- This module adds support for the SDIO interface
- of adapters using WILC chipset. Select this if
- your platform is using the SDIO bus.
+ 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.

bool "SPI support"
---help---
- This module adds support for the SPI interface
- of adapters using WILC chipset. Select this if
- your platform is using the SPI 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---
- If your platform don't recognize SDIO IRQ, connect chipset external IRQ pin
- and check this option. Or, Use this to get all interrupts including SDIO interrupts.
+ 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 devision interrupt.
