Subject: [PATCH 3/7] dt-bindings: misc: Add binding for R-Car DAB
Date: Thu, 25 Feb 2021 22:51:43 +0000 [thread overview]
Message-ID: <20210225225147.29920-4-fabrizio.castro.jz@renesas.com> (raw)
In-Reply-To: <20210225225147.29920-1-fabrizio.castro.jz@renesas.com>
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
+
+maintainers:
+ - Fabrizio Castro <fabrizio.castro.jz@renesas.com>
+
+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.
+

+ - enum:
+ - renesas,dab-r8a77965 # R-Car M3-N
+ - renesas,dab-r8a77990 # R-Car E3
