Could we use here a define, something like this:

#define PANEL_TIMING_H(bp, fp, sw) (((bp - 1) << 20) | ((fp - 1) << 8) | (sw - 1))

                 .panel_config = {
                         .timing_h       = PANEL_TIMING_H(4, 8, 41),

                                          ^^
                                          Is this correct? In the manual I
                                          see for the timing H and V settings
                                          the same bitpositions!

> +			(4 /* vfp */<<  8) |
> +			(10 - 1), /* Vertical timing */

#define PANEL_TIMING_V(bp, fp, sw) (((bp) << 20) | ((fp) << 8) | (sw - 1))

and here too ?

and here ...
