Subject: [RFC PATCH 02/21] dt-bindings: PCI: Endpoint: Add DT bindings for PCI EPF Device
Date: Thu, 26 Sep 2019 16:59:14 +0530	[thread overview]
Message-ID: <20190926112933.8922-3-kishon@ti.com> (raw)
In-Reply-To: <20190926112933.8922-1-kishon@ti.com>

Add device tree bindings for PCI endpoint function device. The
nodes for PCI endpoint function device should be attached to
PCI endpoint function bus.
