The simple-card driver currently hard-codes the clk_id parameter in

This still has the limitation that only one clk_id can be configured, but it
should help some more platforms to use simple-card in favor to a more
specific machine driver.
If we want to get more complex usage of clocks in the DT we should be
moving the CODECs over to using the standard clock bindings for this
stuff rather than inventing custom ASoC clock bindings for it. That way
we don't have to deal with the pain of trying to join things up in the
future.
This will get rather complex too though, because most codec and cpu dais
can act as clock source xor clock consumer, depending on how the
hardware is built. Would you want to represent everything, bit clocks,
frame clocks, master clocks etc as clock nodes?
If that's the case, could you depict how the DT bindings should look
like by example?
Thanks,
Daniel
