Tune dsi frame rate by pixel clock, dsi add some extra signal (i.e. Tlpx, Ths-prepare, Ths-zero, Ths-trail,Ths-exit) when enter and exit LP mode, this signal will cause h-time larger than normal and reduce FPS. Need to multiply a coefficient to offset the extra signal's effect. coefficient = ((htot
