if we compare the SPORT pins requested in these files:

drivers/char/bfin_sport.c

sound/soc/blackfin/bf5xx-i2s.c

sound/soc/blackfin/bf5xx-ac97.c

we see that bfin_sport requests 8 pins, i2s requests 5 pins, and ac97 requests

6 pins ... shouldnt they all request 8 pins ?

Short answer No - certain SPORT modes RFS = TFS and RSCLK = TSCLK. Physically

only TSCLK and one FrameSync are connected.

On some recent parts pinmuxing and peripheral flexibility benefit by this.
