I am working on Audio codec interfacing with hikey960 and facing some issue with slave mode configuration in hikey 960. I could not find any specific code related to slave mode configuration. Actually I want to connect an external audio codec (Analog Device Eval- AD1777z ) to i2s0 of hikey960 through the low speed expansion connector. By default hikey 960 is in master mode. I want to change this master mode to slave mode and use Codec clocks as Bitclock and LRclock.
Can anybody help me to come out from this issue?
