    Subject[PATCH 3/7] dt-bindings: misc: Add binding for R-Car DAB
    Date
    Document bindings for R-Car DAB hardware accelerator, currently
    found on the r8a77990 SoC (a.k.a. R-Car E3) and on the r8a77965
    SoC (a.k.a. R-Car M3-N).

    +title: Renesas R-Car DAB Hardware Accelerator

    +description:
    + The DAB hardware accelerator found on some R-Car devices is a hardware
    + accelerator for software DAB demodulators.
    + It consists of one FFT (Fast Fourier Transform) module and one decoder module,
    + compatible with DAB specification (ETSI EN 300 401 and ETSI TS 102 563).
    + The decoder module can perform FIC decoding and MSC decoding processing from
    + de-puncture to final decoded result.
