Subject: [PATCH 2/2] dt-bindings: imx6q-pcie: add "fsl, pcie-phy-refclk-internal" for i.MX7D
Date: Tue, 13 Aug 2019 11:37:59 +0100 [thread overview]
Message-ID: <20190813103759.38358-2-git@andred.net> (raw)
In-Reply-To: <20190813103759.38358-1-git@andred.net>
The i.MX7D variant of the IP can use either an external
crystal oscillator input or an internal clock input as
a reference clock input for the PCIe PHY.
Document the optional property 'fsl,pcie-phy-refclk-internal'
