Haven't found good ones where you could even see a chip (let alone 
markings) in the vicinity of the hdmi connector.

/me trying to explain something and confusing people :) Sorry for that. 
The whole dts has actually one place where the TLMM 119 is explicitly 
specified, on the hdmi-bridge. It is defined again on the tlmm node for 
pinctrl as hdmi_bridge_en (function gpio), so far so normal. gpio 119 
(on the TLMM) is also defined and used as edp_hpd_default on the 
mdss_dp3 node, there with function edp0_hot.

You need the hdmi_bridge_en and the edp_hpd definition in the dts for 
both to work. And both use gpio 119, on the TLMM, which might be a bit 
confusing.

with best regards
