#1463487 — [PATCH v10 8/9] arm: dts: mt2701: Add clock controller device nodes

From: James Liao <jamesjj.liao@mediatek.com>

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.

This should go through arm-soc tree, so do you need a stable
branch in clk tree to pull through arm-soc, or are we going to
wait a release cycle on the dts patches?

Hi Stephen,

I prefer to wait a release cycle. We may merge clk driver first, then
merge dts patches in next kernel release.


Best regards,

James
