Subject: [PATCH 4/4] arm64: dts: rockchip: add analog audio on Quartz64
Date: Tue, 17 Aug 2021 12:11:19 +0200	[thread overview]
Message-ID: <20210817101119.423853-5-frattaroli.nicolas@gmail.com> (raw)
In-Reply-To: <20210817101119.423853-1-frattaroli.nicolas@gmail.com>

On the Quartz64 Model A, the I2S1 TDM controller is connected
to the rk817 codec in I2S mode. Enabling it and adding the
necessary simple-sound-card and codec nodes allows for analog
audio output on the PINE64 Quartz64 Model A SBC.
