DI0_DISP_CLK on 1.8V or 2.775V?   Schematics and datasheet contradict.

We are designing an expansion board for the QSB for demo purposes.

 

In the IMX53QSB schematics (rev. D), in the expansion header description, the DISP0_DCLK signal has a "1.8V" label.

 

However, it directly connects to the IMX53 IPU DI0_DISP_CLK (pin H4), which according to the datasheet (rev. 4), is on the NVCC_LCD power rail. This is 2.775V.

 

What is correct, 1.8V or 2.775V?

 

The same question goes for GPIO_0 (CLK0)?
