For example:

1) USB based display adapter, such as FL2000DX[1] which use
    the it66121 HDMI transmitter to convert the RGB888 to HDMI.


2) Simple 2D PCIe display controller, such as SM750(EMPV-1201)
    which using sii9022 HDMI transmitter to convert the RGB888
    to HDMI.


3) Some FPGA PCIe Board (sil9136)

4) Be able to run unit test of drm bridges on X86.
