Re: [alsa-devel] [PATCH] Sound: sgtl5000 Allow codec clock frequency to be set.

• Example:

  codec: sgtl5000@0a { compatible = "fsl,sgtl5000"; reg = <0x0a>;

• clock-frequency = <20000000>;

• clocks = <&clks 162>; /* cko1 */

The code looks okay, but I'm not sure this example is right. The binding says that clock-frequency is optional if 'clocks' is provided, but here you list both. You should probably have two examples.
