Let's start from the end:

Most of fishy workarounds that you commented is caused the fact the mmio
of this clock controller is divided into two parts. Compare it with
axg-audio driver, things that was part of contigous memory region (like
pdm) here are moved to second region. Is this enough to make a guess
that these are two devices?

Concerning AUD2_CLKID_AUDIOTOP clock, as it turned out, it must be
enabled before enabling of clocks from second region too. That is
AUD2_CLKID_AUDIOTOP clock feeds both parts of this clock controller.

Except one thing... Here I keep memory identifier to which this clock
belongs:

    .map = AUDIO_REG_MAP(_reg),	

It is workaround, but ->map the only common field in clk_regmap that
could be used for this purpose.

Yep. I could define something like AUDIO_PCLK_GATE().

This implementation uses two regmaps, and this field allow to avoid

This only reason why it is not "static const" because I need to set
unique name for each regmap.

A little paranoia. Here AUDIO_SW_RESET0 is handled as map0's register,

This is all in order to keep range's identifier together with offset and
