I just merged the ben-wpan-atben branch into ben-wpan on [email protected]:qi-kernel.git
This adds the spi_atben driver for atben, replacing spi_gpio. spi_atben [1] is heavily optimized for the Ben hardware. The average throughput for copies to/from the transceiver's frame memory with spi_gpio was about 0.82 Mbps. With spi_gpio, it's 4.2 Mbps. The theoretical maximum the transceiver allows would be 6.76 Mbps. When building the kernel in the ben-wpan branch, the config option for spi_atben will show up as ATBEN 8:10 SPI interface (SPI_ATBEN) [N/m/y/?] (NEW) I've also included it in the example config file [2]. Note that the latter doesn't include the MMC driver. Still need to think about how to share the 8:10 card slot between the two drivers.
