We purchased Audio Mezzanine board from the below link
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
The following are known issues on the current release.
Not Yet Supported
Expansion bus audio. (At present Bluetooth audio and HDMI are supported)
Do we know when can we expect this feature gets enable?
