Hi,

Thank you for sending the patches over!

A few nitpicks.

+title: SiFive fu740 PCIe host controller
+
+description:
+  SiFive fu740 PCIe host controller is based on the Synopsys DesignWare
+  PCI core. It shares common features with the PCIe DesignWare core and
+  inherits common properties defined in
+  Documentation/devicetree/bindings/pci/designware-pcie.txt.

[...]

In the above title and description it would be "FU740" to keep this
consistent with everything else.

Also, as this is a YAML file, a multi-line description might be better
expressed as "description: |" or "description: |+", of course it depends
on whether you would like or not to preserve line endings.

[...]

+  dma-coherent:
+    description: Indicates that the PCIe IP block can ensure the coherency
+
+  bus-range:
+    description: Range of bus numbers associated with this controller.

[...]

+  resets:
+    description: A phandle to the PCIe power up reset line
+
+  pwren-gpios:
+    description: Should specify the GPIO for controlling the PCI bus device power on
+
+  perstn-gpios:
+    description: Should specify the GPIO for controlling the PCI bus device reset

[...]

All the above descriptions should end with a period, so that we keep
things consistent throughout.
