    Subject[PATCH 0/6] usb: dwc3: Calculate REFCLKPER et. al. from reference clock
    Date
    This is a rework of patches 3-5 of [1]. 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.
