Summary0003722: Image on ET070080 is sometimes shifted to the left on efusA9
DescriptionIn Linux, the image on EDT display ET070080 is sometimes not centered on the display, it is shifted to the left. The amount of shifting (offset) depends on the display, some displays have more offset, some less, some are even correct.

We assume that the display has problems when there are high levels on the data and clock signals before the logic voltage is activated. Unfortunately, some signals have either pull-ups by default or use the keeper function. So we can not guarantee that the signals are all low.

We should switch them to low as soon as possible, for example by enabling the internal pull-down on the display signals.
