Subject: [PATCH v2 7/7] arm64: dts: ipq6018: Use reference clock to set dwc3 period
Date: Tue, 18 Jan 2022 19:24:37 -0500 [thread overview]
Message-ID: <20220119002438.106079-8-sean.anderson@seco.com> (raw)
In-Reply-To: <20220119002438.106079-1-sean.anderson@seco.com>
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.
