>From the given logs, I can see that the LSPCON FW version is still old (1.60)
DP branch device present: yes
                Type: HDMI
                ID: MC2800
                HW: 2.2
             -> SW: 1.60
                Max TMDS clock: 600000 kHz
                Max bpc: 16

This was a problem in MCA LSPCON FW. We have worked with MCA, to get this
problem fixed in, and MCA has released FW version 1.70 (which is already
deployed in KBL devices in Grid, by Tomi).

We are also working on making a Linux based FW flashing tool. Once this is
done, we will make the FW and tool available to end users, so that they can get
rid of this issue.
