Subject: [PATCH 3/9] ASoC: meson: aiu: add audio output dt-bindings
Date: Thu, 13 Feb 2020 16:51:53 +0100 [thread overview]
Message-ID: <20200213155159.3235792-4-jbrunet@baylibre.com> (raw)
In-Reply-To: <20200213155159.3235792-1-jbrunet@baylibre.com>
Add the dt-bindings and documentation of the AIU audio controller.
This component provides most of the audio outputs found on the Amlogic
Gx SoC family.
