- * Logic for the below structure :
- * user enters the CEA or VESA timings by specifying the HDMI/DVI code.
- * There is a correspondence between CEA/VESA timing and code, please
- * refer to section 6.3 in HDMI 1.3 specification for timing code.
- *
- * In the below structure, cea_vesa_timings corresponds to all OMAP4
- * supported CEA and VESA timing values.code_cea corresponds to the CEA
- * code, It is used to get the timing from cea_vesa_timing array.Similarly
- * with code_vesa. Code_index is used for back mapping, that is once EDID
- * is read from the TV, EDID is parsed to find the timing values and then
- * map it to corresponding CEA or VESA index.
