Required properties:
- compatible: "atmel,asoc-wm8904"
- atmel,model: The user-visible name of this sound complex.

+ - clock-output-names: Driver related clock names. Shall contain "pck0".
The word "driver" doesn't need to appear in biding documents, and this
fails to describe what it sets out to. How about the following:
- clocks: a list of phandle + clock-specifier pairs, one for each entry
in clock-names.
Agreed.
- clock-names: Should contain "pck0"
After thinking a bit more about it, this can be any programmable clk (pckX).
Huh?
The clock-names property describes the names of the inputs to the
device, from the view of the device, not the names of the clocks fed
into those inputs.
What are the names of the clock input lines on the wm8904?
mclk, and you're right, this is how we should name the clk (I just got
influenced by the existing driver, which was requesting pck0).
This gives the following:
- clock-names: Should contain "mclk"
Do you agree ?
Cheers,
Mark.
