bb631af3d5 clk: at91: optimize clk_round_rate() for AUDIO_PLL
Stop the search for parent rate when exact match is found.

This makes for 3 clk_round_rate() calls instead of 64 of them on
SAMA5D2-based board when searching for 12.288MHz clock.

62061d357c clk: at91: move DT compatibility code to its own file
Move all the DT backward compatibility code to its own file so it can be
deleted later.

08979ee55a clk: at91: audio-pll: separate registration from DT parsing
Separate registration out of of_sama5d2_clk_audio_pll*_setup to allow other
code to use it.

7fa75007b7 clk: at91: audio-pll: fix audio pmc type
The allocation for the audio pmc is using the size of struct clk_audio_pad
instead of struct clk_audio_pmc. This works fine because the former is
larger than the latter but it is safer to be correct.

0865805d82 clk: at91: add audio pll clock drivers
This new clock driver set allows to have a fractional divided clock that
would generate a precise clock particularly suitable for audio
applications.

The main audio pll clock has two children clocks: one that is connected
to the PMC, the other that can directly drive a pad. As these two routes
have different enable bits and different dividers and divider formulas,
they are handled by two different drivers. Each of them could modify the
rate of the main audio pll parent.

The main audio pll clock can output 620MHz to 700MHz.
