Enable MI2S_1_MCLK mclock for external codec

Hi team,

Can you please tell me how to enable or configure gpio_116 as a MI2S_1_MCLK for external codec mclk.

Arjun salariya

is there any update?

@arjun.salariya Have you tried these instructions? https://github.com/96boards/documentation/blob/master/consumer/dragonboard/dragonboard410c/guides/enable-ls-i2s.md

This should get MCLK output on gpio_116 I believe.

Hi mani,

Thanks for response,

i have tried instruction which you suggest but it doesn’t get any success.
Can you please share 0x07702004 (spkr_iomux) and 0x07702000( mic-iomux) register description for enable mclk and External Secondary MI2S MUX with Quatenary MI2S as full duplex. i can’t find above register description in HRD as well.
