I'm not too familiar with the Exynos platform, but wouldn't it make sense to
use a common name across IP cores for interface and function clocks ?
Yes, it would definitely make sense, provided we are starting from
scratch, but due to the lack of listed IP clock inputs in documentation,
we ended with a custom of naming the inputs after SoC clocks of first
SoC used with such driver. This showed up long before adoption of DT and
common clocks on Samsung platform and I'd say it would be hard to get
rid of it now.
Anyway, as long as clock names are well specified in binding
documentation, it should be fine. So, from me it's a
