Message-ID<tWx69-7Yt-1@gated-at.bofh.it>
This patch series based on v4.12-rc1, include MT2701 ethernet/disp bls/display function DT nodes.

Change in v3:
1. Sorting according to name in mt2701-evb.dts
2. Really remove redundant dispsys@14000000 node

Change in v2:
1. Add reset properties in ethernet nodes
2. Split bls nodes into two patches for dtsi and actual board
3. Remove redundant dispsys@14000000 node
