ARM: dts: imx7d: Add node for PCIe PHY (27f7717e) · Commits · 戴 / test

This adds the PHY as a new node. The PCI-e controller node gains a phandle property that points to it. There isn't yet any code in the kernel that uses this device's registers, but it will be added for a PCIe PLL erratum workaround. Signed-off-by:
