Subject: [PATCH] arm: dts: atmel: graph_child_address warning fixes

From: [email-masked] (Rob Herring)
Date: Tue, 8 May 2018 08:59:25 -0500

Addresses for graph ports and endpoints are not necessary when
there's only a single child. Fix the following warnings removing
unnecessary addresses on OF graph nodes:

Warning (graph_child_address): /ahb/apb/hlcdc at f0030000/hlcdc-display-controller: graph node has single child node 'port at 0', #address-cells/#size-cells are not necessary
Warning (graph_child_address): /ahb/apb/hlcdc at f0030000/hlcdc-display-controller/port at 0: graph node has single child node 'endpoint', #address-cells/#size-cells are not necessary
Warning (graph_child_address): /ahb/apb/isi at f0034000/port: graph node has single child node 'endpoint', #address-cells/#size-cells are not necessary
Warning (graph_child_address): /panel/port at 0: graph node has single child node 'endpoint at 0', #address-cells/#size-cells are not necessary
