Hi Folks,

I'm using i.mx8qxpmek  and 4.9.51 Distro, I've connected MIPI DSI to HDMI converter having adv7535.
Now my query is its does not seem to have any audio connection provision on i.mx8qxpmek , so i pulled out SPDIF_TX from processor to ADV7535 (MIPI DSI to HDMI Conv.)'s  SPDIF/I2S pin.
SCLK/MCLK and LRCLK are connected with GND at ADV7535 side as from ADV7535 data sheet it says master clock can be ignored.


I've used fsl-imx8mq-evk-dual-display.dts to start HDMI and it works fine with video but how can i get audio working with the above mentioned hardware connection.
I've also gone through AN12188  Rev. 0 , but did not get any clue related to audio.


Requested to en-light me on this.


Thanks & Regards,
