[PATCH 04/13] ASoC: dt-bindings: tegra: Few more Tegra210 AHUB modules

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch adds YAML schema for DT bindings of few AHUB modules.
These devices will be registered as ASoC components and bindings
will be used on Tegra210 and later chips. The bindings for below
mentioned modules are added:

 * SFC (Sampling Frequency Converter)
 * MVC (Master Volume Control)
 * AMX (Audio Multiplexer)
 * ADX (Audio Demultiplexer)
 * Mixer

+title: Tegra210 ADX Device Tree Bindings
+
+description: |
+  The Audio Demultiplexer (ADX) block takes an input stream with   up to
+  16 channels and demultiplexes it into four output streams of up to 16
+  channels each. A byte RAM helps to form output frames by any combination
+  of bytes from the input frame. Its design is identical to that of byte
+  RAM in the AMX except that the data flow direction is reversed.
