[RFC v5 08/12] arm64: dts: mt8173: Add display subsystem related nodes

Philipp Zabel p.zabel at pengutronix.de
Wed Nov 4 03:45:05 PST 2015


From: CK Hu <ck.hu at mediatek.com>

This patch adds the device nodes for the DISP function blocks
comprising the display subsystem.

---
TODO:
 - The power-domain property should be added to all blocks
   that are in the MM power domain.
 - The iommus property should be removed from the mmsys node.
