Can you describe the flickering in detail?
Is it the backlight or is it missing sync or something else?
Does it look as if the sync frequency is too low? (this was fixed long ago in U-Boot when running on DM3730 vs. OMAP3530 because they need different initializations)
Does it disappear after a while or after doing specific commands?
Does it always occur or only sometimes?

It could also be something with internal clock disable/enable and
PLL frequency dividers. If any one is not correct after resume the
display will show strange things.
