1* Rockchip Rk3328 internal codec
2
3Required properties:
4
5- compatible: "rockchip,rk3328-codec"
6- reg: physical base address of the controller and length of memory mapped
7  region.
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 clock-names.
10- clock-names: should be "pclk".
11- spk-depop-time-ms: speak depop time msec.

13Optional properties:
14
15- mute-gpios: GPIO specifier for external line driver control (typically the
16              dedicated GPIO_MUTE pin)
