Subject: [PATCH 24/25] arm64: dts: meson: a1: add audio devices
Date: Fri, 15 Mar 2024 02:22:00 +0300

This commit adds the declarartion of currently supported audio devices
and their pins found Amlog A1 SoC family. SPDIF declaration is missing
here becase there are no publicly available boards with it.
