Subject: [PATCH] arm64: dts: meson: add audio playback to P212
Date: Thu, 13 Jan 2022 04:45:46 +0000 [thread overview]
Message-ID: <20220113044546.16856-1-christianshewitt@gmail.com> (raw)
Add initial audio support limited to HDMI i2s.
Signed-off-by: Christian Hewitt <christianshewitt@gmail.com>

The P212 dts is widely used with Android box devices that follow the
reference design. The real P212 development board probably has many
more audio capabilities, but as a minimum we can enable HDMI output
and help box users too.
