imx8mm dsd pinctrl

[Brady]

Hi,

In our project we need to get the dsd audio playback supported. we use the SAI1 as platform, and ES9038pro as codec, we got a bit confused on the dsd pinctrl connection.

-  there from dst file looks like we should use TX_BCLK, TX_DATA0, TX_DATA1 as dsd clk and L&R data.

-  I also found there have instrument say imx8mm's pcm and dsd is able to switch smoothly, not sure whether it means dsd output and i2s share the same pins. if use the same as i2s should use TX_SYNC,TX_BCLK,TX_DATA0 pins. 

 then i come to datasheet there so not have details description neither.

please help us to confirmed which pins from imx8mm we should use for dsd audio output. 

 Thanks very much.
