Hi,
I am try to setup PCMD3140 on our board(IMX8MQ) with 4 PDM microphone input.
Currently, ASI output channel format as TDM mode and setup 4 channel input, ch1 and ch2 is working well, but ch3 and ch4 is not working.
I also according example on datasheet to setup configuration, but ch3 and ch4 still not working.
According DEV_STS0 Register(0x76), seem ch3 and ch4 power state is incorrect.
Whole register information as below.
0 1 2 3 4 5 6 7 8 9 a b c d e f 0123456789abcdef
