The Pulse Density Modulated Microphone Interface (MICFIL) is a popular way to deliver audio from microphones to the processor in several applications, such as mobile telephones. However, current digital-audio systems use multibit audio signal (also known as multibit PCM) to represent the signal. This block implements the required digital interface to provide a 24-bits audio signal from a PDM microphone bitstream in a configurable output sampling rate. This patch adds initial support for PDM MICFIL IP found on i.MX8MP board. Signed-off-by: Daniel Baluta <daniel.baluta@nxp.com> |
