power supply question for HDMI port on i.MX^

HDMI_VPH has a range of 2.25-2.75V, and is connected to 2.5V in the Sabre design.  The pullups on HDMI_HPD and HDMI_CEC_IN (not connected) are 3.3V.  Is this safe to do?  Why not use 2.5V on the CM2020's LV_Supply (or does this
cause problems for the CPU's 2.5V LDO or the HDMI output)?
