We purchased Audio Mezzanine board from the below link
https://www.arrow.com/en/products/audiomezz/seeed-technology-limited
Connected Audio Mezzanine board to hikey960 expansion header.
However I don’t see i2s0_pmx_func, i2s0_cfg_func these pin controls are mapped into hi3660.dtsi file
Please help me to configure these pins into “hi3660.dtsi” along with right “dmas”
And I guess we need to make some changes in sound/soc/hisilicon/hisi-i2s.c to drive pcm data to SIO0(Sonic input/output).
SIO0 is SIO_AUDIO, which plays and records music, and supports the inputs and outputs in the I2S and PCM formats
We found from the below link
