Since rtq9128 can support 4 channel I2S mode audio data, there are two dedicated data input pins for CH12 and CH34. But in TDM mode, input source was already drived on one data pin for multiple data slots. In this case, only one input source is needed for TDM mode.
This patch is to add the data source pin selection for CH12 and CH34.
- SOC_ENUM("CH12 TDM Data Select", rtq9128_ch12_tdm_data_select_enum),
- SOC_ENUM("CH34 TDM Data Select", rtq9128_ch34_tdm_data_select_enum),
Is this something that's going to be changing dynamically at runtime or should this be a device property that's set either by firmware or when we're doing the TDM setup? This sounds like something I'd expect to be fixed by the board design.
