This patch adds support for audio CODEC core of rk3328. Rockchip does not publish detail specification of this core but driver source code is opened on their GitHub repository. https://github.com/rockchip-linux/kernel So I ported this code to linux-next and added some trivial fixes.

* Rockchip Rk3328 internal codec
|
|
|
|
Required properties:
|
|
|
|
- compatible: "rockchip,rk3328-codec"
|
|
- reg: physical base address of the controller and length of memory mapped
|
|
region.
|
|
- rockchip,grf: the phandle of the syscon node for GRF register.
|
|
- clocks: a list of phandle + clock-specifer pairs, one for each entry in clock-names.
|
|
- clock-names: should be "pclk".
|
|
- spk-depop-time-ms: speak depop time msec.
|
|
|
|
Example for rk3328 internal codec:
|
|
|
|
codec: codec@ff410000 {
|
|
compatible = "rockchip,rk3328-codec";
|
|
reg = <0x0 0xff410000 0x0 0x1000>;
|
|
rockchip,grf = <&grf>;
|
|
clocks = <&cru PCLK_ACODEC>;
|
|
clock-names = "pclk";
|
|
spk-depop-time-ms = 100;
|
|
status = "disabled";
|
|
};
