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

[Xuebing Wang]

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 at 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 at 0202c000)
- External AUD6 -> internal SSI1 (ssi at 02028000)

Thanks.
