I'm surprised you didn't pick up on this, but there are actually _2_

i noticed this, the reference clock source can be supported by clocks as
you suggested here, it is really helpful.
What is the impact of using the 48 MHz or 96 MHz internal reference?
They works on the different IPQ platform, 96MHZ internal reference is
used on IPQ5018, the internal 48MHZ is used on the IPQ5332, that is
So the binding is just incorrect. Why do you even consider configuring
96 MHz internal reference on IPQ5332?

Normally there is the fix reference clock source used per each IPQ
platform, but we should keep it configurable, the CMN PLL block is
same among the supported IPQ platforms, Maybe there is special case
to switch the reference clock in the future.
i will also update the dtbinding doc to limit the reference clock based
on the compatible string.
