We usually use hyphen rather than underscore in node name.

The "okay" status is usually used to flip "disabled" one. It's not
really needed here.

Please use a generic node name.

The compatible string should have a vendor prefix. You should probably
find one from Documentation/devicetree/bindings/hwmon/lm75.txt.

Node name should be generic, while label name could be specific.
I would suggest the following names:
tlv320aic32x4: audio-codec {
...
};
