[PATCH 2/4] clk: exynos-audss: allow input clocks to be specified in device tree

Hi Tomasz,

Well, this is basically how it should be done, but in current state of
clock core I can see a problem: can we really rely on the order of clock
initialization? I mean, we can't defer initialization of particular clock
controller until all external clocks it needs are available, because there
is no probing involved here.

Right, we can't.  The reason I added the device-tree lookup of input
clocks was because Exynos5420 has different names for several of the
input clocks to the audio block.  We already need a separate
compatibility string because of the ADMA clock, so we could just use
that to determine the parent clock names.  It's not ideal, but it's a
workaround for the initialization order issue.  Thoughts?

Thanks,
Andrew
