15description: |
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.
