[PATCH v4 4/4] arm64: dts: rockchip: add analog audio on Quartz64

Nicolas Frattaroli
2021-09-03T23:16:43Z

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.
