    ASoC: meson: add tdm interface driver · d60e4f1e
    Jerome Brunet authored
    Add Amlogic's axg TDM interface driver. This driver manages the format
    and clocks provided on the pads.
    
    On this SoC, each stream direction provides 4 serial lanes. This makes
    a maximum of 8 channels in i2s modes and 128 channels in DSP modes.
    
    While each lanes operate on the same slot number (same bit clock), they
    may have different TDM masks. This requires to provide a function to let
    the card set the 4 masks, in lieu of the usual set_tdm_slots() callback
    of the dai driver.
