Hi Mars,

Sean reworked the scpsys driver to remove code duplication, see:
http://lists.infradead.org/pipermail/linux-mediatek/2017-August/009687.html
http://lists.infradead.org/pipermail/linux-mediatek/2017-August/009820.html

I think current driver will have conflict and can't merge as-is, you'll
need to rebase to Matthias' for-next branch.

Joe.C

Yes, please rebase, which should be trivial. Other then that the scpsys driver 
looks good.

Thanks for your review. I will rebase it and send the patch again soon.
