The nt36672a panel from Tianma is a FHD+ panel with a resolution of 1080x2246
and 6.18 inches size. It is found in some of the Poco F1 phones.

I think the pinctrl should go in the DSI controller node, not the 
display unless it is settings for 'reset-gpios'.

For a single port, you can do just 'port' (without ports node).

Yes, from the downstream code, this seems to be for reset-gpios.
