This patch adds MIX (Mixer) initial support for rsnd driver.
It is assuming that this MIX is used via DPCM.
This is sample code for playback.
CPU0 : [MEM] -> [SRC1] -> [CTU02] -+

+-> [MIX0] -> [DVC0] -> [SSI0]

CPU1 : [MEM] -> [SRC2] -> [CTU03] -+
sound {
compatible = "renesas,rsrc-card";
...
cpu@0 {
sound-dai = <&rcar_sound 0>;
};
cpu@1 {
sound-dai = <&rcar_sound 1>;
};
codec {
...
};
};
rcar_sound {
...
rcar_sound,dai {
dai0 {
playback = <&src1 &ctu02 &mix0 &dvc0 &ssi0>;
};
dai1 {
playback = <&src2 &ctu03 &mix0 &dvc0 &ssi0>;
};
};
};
