DS90UB926Q-Q1: ds90ub926 and ds90ub925 debug issue

Part Number: DS90UB926Q-Q1

Here attached are the detailed issue description In English and Chinese and SCH from the customer. Please helps.

Project introduction:
We designed a module using ds90ub926 and ds90ub925, which is used as repeater mode
to increase one channel video output. It is installed between the original navigation host
(using ds90ub921) and the touch display module (using ds90ub924).
Problem points:
We set the I2C register of 926 and 925 to pass_ All, the I2C at the other end of the screen
can detect the waveform, and the two-way image output display is normal, but the touch
can't be used. We turn on the interrupt and find that the level of the interrupt pin on our
board has been always pulled down.
