Subject[PATCH v2 0/2] drm/komeda: Add writeback downscaling split support
Date
Writeback split is also for workaround the size limitation of d71 scaler.
Like layer_split, writeback downscaling also can use two scalers to handle
the scaling half-by-half. The only differnence is writback needs a
standalone component (splitter)'s help to split the composition result.
The data pipeline of writeback split as below:

/-> scaler-0 ->\
compiz -> splitter merger -> wb_layer -> memory
\-> scaler-1 ->/

Depends on:
