From 9c76dd09d27dff05207241aa67a2c6054d057b32 Mon Sep 17 00:00:00 2001
From: Sean Wang <sean.wang@mediatek.com>
Date: Thu, 28 Dec 2017 10:30:32 +0800
Subject: [PATCH 210/224] arm64: dts: mt7622: add clock controller device nodes
Add clock controller nodes for MT7622 and include header for topckgen,
infracfg, pericfg, apmixedsys, ethsys, sgmiisys, pciesys and ssusbsys
for those devices nodes to be added afterwards.
In addition, provides an oscillator node for the source of PLLs and dummy
clock for PWARP to complement missing support of clock gate for the
wrapper circuit in the driver.
