Subject: [PATCH] arm64: dts: ipq6018: Use reference clock to set dwc3 period
Instead of manually setting snps,ref-clock-period-ns, we can let the
driver calculate it automatically from the "ref" clock. I haven't
reviewed this board's schematics, so please let me know if this is the
wrong 24MHz clock to use.
