Additionally, add and connect output port for DSS (vp2), input and output ports for the sil9022 HDMI tx and the input port for the HDMI connector. The sil9022 HDMI tx is connected on the i2c1 bus. The HDMI connector on the board is of type "a". The clock frequency of the master clock that supports the HDMI tx is 12.288 MHz. The dpi output signals from the vp2 of DSS are fed into the sil9022 HDMI transmitter. These signals are converted into HDMI signals which are further passed on to the HDMI connector on the board, on which display can be connected via appropriate HDMI cables.
