Subject: [PATCH] arm: dts: mt2701: Add clock controller device nodes
Add clock controller nodes for MT2701, include topckgen, infracfg,
pericfg, apmixedsys, mmsys, imgsys, vdecsys, hifsys, ethsys and
bdpsys. This patch also add two oscillators that provide clocks for
MT2701.
Signed-off-by: James Liao <jamesjj.liao@...iatek.com>
---
This patch is based on v4.6-rc1 and MT2701 clock patches [1]. This
patch adds all clock provider nodes which are supported in [1].
