Control TV tunner via CEC HDMI from LM5

[Hadeel]

Hi !
We have a project which we want to control TV tunner via CEC HDMI and I found this article.
https://openrb.com/control-tv-via-cec-hdmi-from-lm4/

This is the example on LM4 but can we do the same thing on LM5?

Thank you for your help in advance!
