From: Douglas Anderson <diand...@chromium.org>

Jitter was improved by lowering the MPLL bandwidth to account for high
frequency noise in the rk3288 PLL.  In each case MPLL bandwidth was
lowered only enough to get us a comfortable margin.  We believe that
lowering the bandwidth like this is safe given sufficient testing.
