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.
