I've been using the iMX6q_sabreauto board with linux-2.6-imx.git imx-android-r13.4-ga.

Attached I have a HannStar LVDS display and also an iAP auth chip.

Both LVDS and auth chip are available on i2c-1. The TS driver used is egalax.

LVDS is the first one to be initialized then followed by a procedure on the auth chip. After the auth, the LVDS is freezed for ~3-4 sec and then it becomes reactive again.


I can also confirm that if I try to use the TS during the freeze period while doing a "getevent", not input event is received.


I think a similar issue has been mentioned here:


Does anyone have an idea about the root cause ?
