5 - compatible: "rockchip,rk3308-codec"
6 - reg: The physical base address of the controller and length of memory
8 - rockchip,grf: The phandle of the syscon node for GRF register.
9 - clocks: A list of phandle + clock-specifer pairs, one for each entry in
10   clock-names.
11 - clock-names: It should be "acodec".
12 - resets : Must contain an entry for each entry in reset-names.
13 - reset-names : Must include the following entries: "acodec-reset".
16 - rockchip,enable-all-adcs: This is a boolean type property, that shows whether
19   * grp 0 -- select ADC1 / ADC2
20   * grp 1 -- select ADC3 / ADC4
21   * grp 2 -- select ADC5 / ADC6
22   * grp 3 -- select ADC7 / ADC8
26 - rockchip,adc-grps-route: This is a variable length array, that shows the
27   mapping route of ACODEC sdo to I2S sdi. By default, they are one-to-one
