It attempts to correctly program REFCLKPER and REFCLK_FLADJ based on the reference clock frequency. Since we no longer need a special property duplicating this configuration, snps,ref-clock-period-ns is deprecated. Please test this! Patches 3/4 in this series have the effect of programming REFCLKPER and REFCLK_FLADJ on boards which already configure the "ref" clock. I have build tested, but not much else.
