Subject: [PATCH v8 2/3] dt-bindings: PCI: pci-imx6: Add external reference clock input
Date: Fri, 24 Oct 2025 10:40:12 +0800 [thread overview]
Message-ID: <20251024024013.775836-3-hongxing.zhu@nxp.com> (raw)
In-Reply-To: <20251024024013.775836-1-hongxing.zhu@nxp.com>
i.MX95 PCIes have two reference clock inputs: one from internal PLL, the
other from off chip crystal oscillator. The "extref" clock refers to a
reference clock from an external crystal oscillator.
Add external reference clock input for i.MX95 PCIes.
