DS90UB948-Q1: how to enable I2S on DS90BS941 DS90UB948?

Part Number: DS90UB948-Q1

Hi 

We had established the FPD LINK III for lvds, we want to verified the I2S function for futrue design.

function Block

WM8960 is using I2S_DA / I2S_WC/ I2S_CLK for playing audio.

It control those pins sending signal to SAI3, but in this case, those pins are always high.
