Thanks Konrad.

I just realized that, in commit message, the statement "APSS PLL will be 
running at 800MHz" should be "APSS clock / CPU clock will be running at 
800MHz".

Bjorn, will you be able to fix it up while applying (all 4 DTS changes 
needs update) or shall I respin it?

Thanks,

Kathiravan T.
