This patch introduces property "snps,refclk-period-ns" to inform the controller of the reference clock period. If the reference clock period is different from the default Core Consultant setting, then this property can be set to the reference clock period. This property does not control the reference clock rate. The controller uses this value to perform internal timing calculations that are based on the reference clock.
