The currently listed dotclock disagrees with the currently listed vrefresh rate. Change the dotclock to match the vrefresh.
Someone tell me which (if either) of the dotclock or vreresh is correct?
The 40 MHz clock comes from the datasheet which states this as the typical clock frequency. But the valid range reaches from 30 MHz to 50 MHz. The datasheet also states a 60 Hz frame rate so setting the clock to the corresponding frequency makes sense to me.
I gave it a little test here and both values work for me.

This display (a controller is included) has a wide tolerance range.
Adapting clock should be fine while keeping vrefresh rate at 60 Hz.
I guess an even better alternative would be to change this config to a pixelclock describing one like the other auo panels.
But at the moment I'm not having a display here.
