I think this table is common to all lucid plls? Maybe we can push it
into the clk_ops somehow and stop duplicating it here?

If this is gpll0 in this file, then this should be a clk_hws pointer
instead and directly pointing to the parent.

These CLK_IS_CRITICAL clks can't be set once at driver probe time and
forgotten about? It would be nice to not allocate memory for things that
never matter.

Wow haven't seen this in some time. There isn't some sort of PLL that
needs configuring or some clks that need to be slammed on with a couple
register writes?

Are you referring to lucid plls in this driver? Because, this table is
not common for other SoCs. And I don't think having this way introduces
any overhead, so I'd prefer keeping it as it is.

Makes sense! But are we moving into the direction of deprecating the use
of CLK_IS_CRITICAL?

Yes all lucid type PLLs probably have the same divider table.
