[alsa-devel] About iMX6SL AUDMUX (port 7) and SSI3

Hi community:

I am working on ASoC based sound driver for our iMX6SL based board. There are 3 I2S peripherals on the board: - iMX6SL pads AUD3 (as in AUD3_TXC), connect to peripheral Codec3 - iMX6SL pads AUD5 connect to Codec5 - iMX6SL pads Aud6, connect to Codec6

Q1) Is internal SSI3 controller (ssi@02030000) actually *hard-wired* to AUDMUX port 7?

Q2) Can I configure audmux as below? - External AUD3 -> internal SSI3 (which is actually audmux port 7?) - External AUD5 -> internal SSI2 (ssi@0202c000) - External AUD6 -> internal SSI1 (ssi@02028000)

Thanks.
