+      }
+   }
+
+In real world usecases,
+
+1. Plane Degamma can be used to linearize a non linear gamma
+encoded framebuffer. This is needed to do any linear math like
+color space conversion. For ex, linearize frames encoded in SRGB
+or by HDR curve.
+
+2. Later Plane CTM block can convert the content to some different
+colorspace. For ex, SRGB to BT2020 etc.
+
+3. Plane Gamma block can be used later to re-apply the non-linear
+curve. This can also be used to apply Tone Mapping for HDR usecases.
+
+All the layers or framebuffers need to be converted to same color
+space and format before blending. The plane color hardware blocks
+can help with this. Once the Data is blended, similar color processing
+can be done on blended output using pipe color hardware blocks.
+
+DRM Properties have been created to define and expose all these
+hardware blocks to userspace. A userspace application (compositor
+or any color app) can use these interfaces and define policies to
+efficiently use the display hardware for such color operations.
