  15 description: |
  16   MIC (Mobile Image Compressor) resides between DECON and MIPI DSI. MIPI DSI is
  17   not capable of transferring high resoltuion frame data as DECON can send. MIC
  18   solves this problem by compressing the frame data by 1/2 before it is
  19   transferred through MIPI DSI. The compressed frame data must be uncompressed
  20   in the panel PCB.
