I2S Audio on Hikey


#1

Hi,

I am trying to use below pins to connect an I2S device.

MODEM_PCM_XFS
MODEM_PCM_XCLK
MODEM_PCM_DO
MODEM_PCM_DI

Is there any instruction on how to enable this interface?
Device tree entry for I2S and audio platform driver details would be helpful.
I am currently using linaro 4.4 kernel.

Regards,
Sharada

Are you able to make it work?


#3

No , there is no platform driver for I2S lines on low power expansion card


#4

Are the i2s data lines and clock lines that exposed at the low-speed expansion header configured for the PCM lines or I need to configure them?

I tried understanding those but no use.

It seems I am missing something.

Can anyone understand about those lines that exposed at the low-speed expansion header on the hikey board?


#5

Do I need to add anything in the dts files like pinctrl ?
