[PATCH RFC 0/3] clk: meson: Refactor PLL pre-divider as a divider clock

[Jian Hu via B4 Relay <devnull+jian.hu.amlogic.com@kernel.org>]

This series refactors the Meson PLL framework to remove the dedicated
PLL pre-divider (N) parameter from the PLL implementation and model it
as a separate divider clock.

Currently, the Meson PLL framework models the PLL pre-divider using a
dedicated n field in struct meson_clk_pll_data. This makes the
pre-divider part of the PLL-specific implementation, although the
Common Clock Framework already provides a generic divider clock.

This series separates the pre-divider from the PLL and makes the PLL
DCO take the pre-divider clock as its parent. This allows the
pre-divider to be modeled using the standard CCF divider implementation
and simplifies the PLL framework.

The series currently covers T7 as an RFC to get feedback on the
framework design before applying the same approach to other SoCs.

Series:
clk: meson: pll: Remove the dedicated n parameter
dt-bindings: clock: amlogic: Add T7 pre-divider clock IDs
clk: meson: t7: Model PLL pre-divider as a divider clock

The other Meson SoCs will be converted separately after the T7 PLL
framework refactoring has been reviewed and the overall approach is
agreed upon.

Any feedback on the proposed clock hierarchy and the separation of the
PLL pre-divider from the PLL itself would be appreciated.
