| 3 | Required properties: |
| 4 | - compatible: "rockchip,rk3399-gru-sound" |
| 5 | - rockchip,cpu: The phandle of the Rockchip I2S controller that's |

| 7 | - rockchip,codec: The phandle of the audio codecs |
| 8 | |
| 9 | Optional properties: |
| 10 | - dmic-wakeup-delay-ms : specify delay time (ms) for DMIC ready. |
| 11 | If this option is specified, which means it's required dmic need |
| 12 | delay for DMIC to ready so that rt5514 can avoid recording before |
| 13 | DMIC send valid data |

| 15 | Example: |
| 16 | |
| 17 | sound { |
| 18 | compatible = "rockchip,rk3399-gru-sound"; |
| 19 | rockchip,cpu = <&i2s0>; |
| 20 | rockchip,codec = <&max98357a &rt5514 &da7219>; |
| 21 | dmic-wakeup-delay-ms = <20>; |
