4a47295144 clk: meson: fractional pll support
Fractional MPLLs are a superset of the existing AmLogic MPLLs. They add
in a couple of new bitfields for further dividing the clock rate to
achieve rates with fractional hertz.

1c50da4f27 clk: meson: add mpll support
MPLLs are adjustable rate clocks derived from PLLs. On both Meson8b and
GXBB they appear to be only derived from fixed_pll.

Add support for these clock types so that they can be added to their
respective drivers.

73de5c8bcf clk: meson: add peripheral gate macro
There are a series of peripheral and system gate clocks that fan out
from the clk81 signal. Add a helper macro to statically initialize these
gate clocks.

c0daa3e6f5 clk: meson8b: clean up composite clocks
Remove the composite clock registration function and helpers. Replace
unnecessary configuration struct with static initialization of the
desired clock type.

To preserve git bisect this patch also flips the switch and starts using
of_clk_add_hw_provider instead of the deprecated meson_clk_register_clks
method. As a byproduct clk.c can be deleted.

55d42c40dd clk: meson8b: clean up cpu clocks
Remove the cpu clock registration function and helpers. Replace
unnecessary configuration struct with static initialization of the
desired clock type.

Ninja rename a5_clk to cpu_clk to better align with cpufreq convention.

e92f7cca44 clk: meson8b: clean up fixed rate clocks
Remove the fixed_rate registration function and helpers from clkc.[ch].
Replace unnecessary configuration struct with static initialization of
the desired clock type.

While we're here, begin the transition to a proper platform_driver and
call of_clk_add_hw_provider with a shiny new struct clk_hw_onecell_data.

7a29a86943 clk: meson: Add support for Meson clock controller
This patchset adds the infrastructure for registering and managing the
core clocks found on Amlogic MesonX SoCs. In particular:

- PLLs
- CPU clock
- Fixed rate clocks, fixed factor clocks, ...
