It is suprising to see that the innolux_g070y2_t02 uses the mode
innolux_at070tn92_mode.
Is it on purpose? If yes then I would expect the changelog to say so.

In most (all?) other cases the panel provide their own mode.

yes.

It works with same timing values. What is the preferred way, add own
mode or extend the changelog?

Both works for me, but I would duplicate the timings.
Only because I do not trust anyone that comes later to see that the
timings are used twice.
