[PATCH 5.10.y-cip 16/16] dt-bindings: pci: rcar-pci-ep: Document missing interrupts property


Lad Prabhakar
 

From: Geert Uytterhoeven <geert+renesas@...>

commit f3c6c120614cfb02827ee7bbe6c4240847cc5f12 upstream.

The R-Car PCIe controller does not use interrupts when configured
for endpoint mode, hence the bindings do not document the interrupts
property. However, all DTS files provide interrupts properties, and
thus fail to validate.

Fix this by documenting the interrupts property.
