2017-09-01clk: at91: add audio pll clock driversQuentin Schulz1-0/+536
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.
