There are 2 devices on the i2c-1 bus. An IO-Expander and an HDMI TX. Both of these are capable of servicing i2c upto a max frequency of 400KHz. However, below warning log shows up while running any userspace application that uses the HDMI display when the main-i2c1 frequency is set at 400KHz. [ 985.773431] omap_i2c 20010000.i2c: controller timed out With some further tests using 2 frequencies, 100 KHz and 400KHz across different HDMI cable & monitor setups, it was observed that, - i2c frequency of 400KHz works fine with standard good quality HDMI cables with branded displays. It will show the controller timeout warnings only when a sub-standard / generic HDMI cable is being used. - Using 100KHz for i2c frequency, stops the warning from showing up for the generic HDMI cables as well. Since, the IO-Expander is the only other component on that i2c bus and we are not performing any intensive operations on it, it would be safe to set the i2c frequency at 100KHz in order to support a broader variety of HDMI cables.

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.
