From 97ecbfb30dca36843d7a456def55e4d19007c3d2 Mon Sep 17 00:00:00 2001 From: Sean Anderson Date: Thu, 27 Jan 2022 15:06:30 -0500 Subject: [PATCH] dt-bindings: usb: dwc3: Deprecate snps,ref-clock-period-ns This property is redundant because we can determine the correct value for REFCLKPER based on the "ref" clock. Deprecate it, and encourage users to provide a clock instead. This also restricts the minimum and maximum to the values documented in the register reference [1].
