Re: [RFC PATCH 3/5] ASoC: audio-graph-card: Add bindings for sysclk and pll

ASoC core provides callbacks snd_soc_dai_set_sysclk() and snd_soc_dai_set_pll() for system clock (sysclk) and pll configurations respectively. Add bindings for flexible sysclk or pll configurations which can be driven from CPU/Codec DAI or endpoint subnode from DT. This in turn helps to avoid hard codings in driver and makes it more generic.

Also add system-clock related bindings, "system-clock-direction-out" and "system-clock-frequency", which are already supported.

This all looks like duplication of what the clock binding can provide. We don't need 2 ways to describe clocks in DT.
