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