Hi Jeff
this could be related to this specific lcd usage (for example some
power up sequence is needed), so one can try to get support from
lcd vendor.

Hi igor
I have checked power up sequence and data written to LCD IC for many times. The IC vendor of LCD used the same data to write to screen and it worked fine. Difference is IC vendor use other platform. Furthermore, the LCD works fine in MTK platform. So, there may be some problems in imx6q DSI source code
