Those four digital microphones support two stereo inputs connected either to the audio codec or, by default,
connected on two DFSDM odd channels of
STM32MP157FAA1: DFSDM_DATA1 and DFSDM_DATA3
synchronized on DFSDM_CKOUT.
The STM32MP157FAA1 DFSDM interface is shared among the four embedded digital microphones and the
extension module on connector MB1262/CN8.
Table 21 describes the HW configuration for the digital microphones.
