PS1, Line 104: pwr_on_vary_bl_to_blon;
             : 	/** Offset 0x04EB**/	uint8_t                     pwr_down_bloff_to_varybloff;
if these UPDs are directly controlling display panel timing delays, would it not be better to name them something like 'edp_panel_t{x}', have the timing values set directly, and do the translation to 4ms units inside FSP?
