For review before submitting things upstream: This set of three patches adds support for the ATBEN IEEE 802.15.4 board, along with the infrastructure needed for the Ben NanoNote. It consists of three parts:
1) addition of a platform-specific reset function to the AT86RF230 driver. The driver assumes that it can reset the transceiver through a reset pin, but ATBEN uses power cycling instead. We therefore need a platform-specific function to perform the reset. 2) addition of an SPI-GPIO driver optimized for the Jz4740. ATBEN connects to a physical MMC interface but uses SPI (with some quirks) for communication. We therefore have to use bit-banging. The SPI-GPIO driver would be too slow, so we introduce a driver optimized for the Ingenic Jz4740 SoC that implements a subset of SPI-GPIO's functionality and is up to about six times faster. 3) last but not least, we add the platform definitions that connect the drivers and devices, and provide the platform-specific reset function. Since all this is specific to the Ben NanoNote, the code goes into arch/mips/jz4740/ Comments welcome. - Werner _______________________________________________ Qi Hardware Discussion List Mail to list (members only): [email protected] Subscribe or Unsubscribe: http://lists.en.qi-hardware.com/mailman/listinfo/discussion
