Hi friends,

  I'm using imx6qp in a new project. some parts of imx6qp are not needed in the application. Such as ETH,HDMI, SATA,PCIE etc. I want to tie all the power pins of these parts to ground to get lower power comsuption and less board space, such as pin HDMI_VPH, HDMI_VP,HDMI_RESREF, is it ok?   Is there any risk if i tie all power pins of unused parts to ground?  any special attention?
