Hello,
We are using SPORT1 and hooking it up to an 1836A codec. We are however not using the TFS1 pin of SPORT1.
Is there a way to modify either the kernel or through menuconfig, so that the TFS1 pin (PG14/gpio30) is no longer dedicated to SPORT1. We want to use this pin as a gpio, but when I go to open "/dev/gpio30", I get an error saying that the resource is busy.
Thanks,
Mark

peripheral_request list.
In case TFS1 is not vital to the snd codec driver...
