You say this "The mainboard LVDS output need to turn off NOSSC(Spread Spectrum function) and turn on the FREERUN function" but the only driver in the Linux kernel that supports turning off NOSSC is i915 (intel integrated graphics).
Please advise on how to do this when other boards and graphics drivers are used, otherwise, this isn't a fair "solution" to provide to people saying "Just do this thing you can't do without reprogramming your LCD drivers".
