This patch series includes changes related to the PLL and peripheral
clocks for both the A4 and A5 SoCs.

The patches for A5 were previously submitted up to V3 by Xianwei.

After friendly coordination, I’ve taken over and continued the
submission as part of this series. The dt-bindings patch retains Rob's
original "Reviewed-by" tag, and I hope this hasn’t caused any
additional confusion.

Both A4 and A5 belong to the Audio series. Judging by their names, one
might assume that A5 is an upgrade to A4, but in fact, A5 was released
a year earlier than A4.

Since there are differences in the PLLs and peripheral clocks between
the A4 and A5 SoCs (especially the PLL), and taking into account factors
such as memory footprint and maintainability, this series does not
attempt to merge the two into a shared driver as was done for
G12A/G12B/SM1.

This patch series includes all related dt-bindings, driver, and dts
changes for the PLLs and peripheral clocks. Following our past convention
for clock-related submissions, the dts changes are placed at the end
and submitted separately. If this ordering makes it harder for
maintainers to review or pick patches, please feel free to point it out.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: using specified base-commit 01f3a6d1d59b8e25a6de243b0d73075cf0415eaf

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)
