Hi, Matthias,

Please hold this one.
This one is based on CCF "arm: dts: mt2701: Add clock controller device
nodes"[1] and power domain patch "Mediatek MT2701 SCPSYS power domain
support v7"[2],
But these two patchset are still being reviewed now.

Do you think it's better that I send this one later after ccf and power
domain patch got merged? I will send this patch later if it's OK with
you.

Thanks.
