[PATCH v4 2/2] clk: bcm2835: Minimise clock jitter for PCM clock

2017-06-01 Thread Phil Elwell
Fractional clock dividers generate accurate average frequencies but with jitter, particularly when the integer divisor is small. Introduce a new metric of clock accuracy to penalise clocks with a good average but worse jitter compared to clocks with an average which is no better but with lower jit
