Blackfin's have a synchronous Serial Peripheral pORT (SPORT). Unlike SPI, UART, I2C, or CAN interfaces which are designed for specific industry standard compatible communication only, the SPORT support a variety (software programmable) serial data communication protocols: - A-law or ยต-law companding according to G.711 specification - Multichannel or Time-Division-Multiplexed (TDM) modes - Stereo Audio I2S Mode - TDM Modes for Multi-Channel audio codecs - H.100 Telephony standard support - others, but if anyone really cares, they need to read the chip specs... Bryan's patch takes the SPORT, and makes a standard UART out of it (exposing /dev/ttySS0) for those people who don't have enough hardware UARTs in their system. Is it a SPORT driver that emulates a UART, or a UART driver on the SPORT? I think it is the latter... Maybe: [PATCH 3/3] Blackfin serial driver: enables a UART interface for the SPORT Which still doesn't make any sense, until you know what a SPORT is :) -Robin
