[PATCH 0/3] drm/komeda: Add layer split support

From: james qian wang (Arm Technology China)

This patch series add laye split support for komeda.

For layer split, a plane state will be split to two data flows and handled
by two separated komeda layer input pipelines. komeda supports two types of
layer split:
- none-scaling split:
/ layer-left -> \
plane_state compiz-> ...
\ layer-right-> /

- scaling split:
/ layer-left -> scaler->\
plane_state merger -> compiz-> ...
\ layer-right-> scaler->/

Since merger only supports scaler as input, so for none-scaling split, two
layer data flows will be output to compiz directly. for scaling_split, two
data flows will be merged by merger firstly, then merger outputs one merged
data flow to compiz.

This patch series depends on:
