JH7100 Audio Clocks

This series add support for the audio clocks on the StarFive JH7100 RISC-V SoC, although the first two patches are fixes to the original addition of the basic clock driver. At least the first fix may be considered for 5.17.

It turns out the SoC has several memory ranges for different clocks, but they all share the layout of the control registers. This could be modelled in 3 ways:

1) Model all the clocks as a single peripheral with multiple memory ranges and have a single driver for them all.
2) Model each memory range as different, but related peripherals with a single driver handling all of them.
3) Model each memory range as different peripherals with separate drivers that can share most code.

Although the first option would require less code this series implements the 3rd option. The basic clock driver has to be built-in to boot the SoC, so separate drivers for the other registers means less code needs to be built-in and can be left as loadable modules.

Emil Renner Berthing (7):
clk: starfive: jh7100: Don't round divisor up twice
clk: starfive: jh7100: Handle audio_div clock properly
dt-bindings: clock: Add JH7100 audio clock definitions
