* [PATCH 02/12] arm64: dts: mt7622: add clock controller device nodes
From: sean.wang at mediatek.com @ 2018-01-04  9:40 UTC (permalink / raw)
  To: linux-arm-kernel
In-Reply-To: <cover.1515057696.git.sean.wang@mediatek.com>

From: Sean Wang <sean.wang@mediatek.com>

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.
