on gta01/gta02 schematics, filter U6002 (Hsync, Vsync, Pclk, DE) has 
IN1-IN4 connected to the LCD, and pins OUT1-OUT4 connected to the 
sc32442/glamo (the rest of the filters are connected the other way round). 

In our schematics, the IN side of all filters are connected to sc32442, 
and the OUT side to LCM.
