This device seems to be used on x86 systems so we'll need to ensure that
they register clocks for this.  They really should set this up using
quirks keyed off DMI information or similar so it's hidden from other
systems.

Hmm..the change defines this mclk as a optional property so I'm
not sure how it would affect x86 systems. (Would love to refine

Ah, clk_prepare_enable() silently ignores NULL as an argument?  It is a
bit messy to do things that way but might be the most practical thing.

it to make it impactless.) Since it's literally hidden, any way
that I can manually ensure it? Or just wait for an ack from x86
developers?

Hopefully they'll speak up - we're in the merge window anyway so it'll
be just over a week before this can go into -next.

Yeah I am not aware of any plan to have clks on x86. For audio we are not
going to use much. ACPI and controller w/ firmware does the job.

I have added Darren, he oversee platform things so might know if clocks
would be there in future..

Thanks
