Thanks, i added some notes inline as I do not know how to proceed with
some if the requirements.
Just to be noted, the sm8550-samsung-q5q.dts it is based on
sm8550-mtp.dts so most of the stuff is from there

The [PATCH] string is added automatically to the subject by b4, I don't
know how to add/insert custom text in there, I am going to read the b4
docs and see if i can spot how to do it.
Your commit title now includes "V2". Move it inside the square braces the
next time around, so it's like [PATCH v3 1/2]. With b4, this should be done
automagically, though..

I have removed the nodes that uses this as the driver for "Texas

those are took from the existing sm8550-mtp.dts
How to proceed?
Any particular reason as to why?

Those are took from the device's running Android /firmware and load
without error, I used this kind of firmware loaded on other devices as
well and seems to do the job, the lines are as well on existing
sm8550-mtp.dts
How to proceed?
Unless you stole one from the factory, these firmwares will not
load on your phone..

I have no idea, i took the ranges from the running Android FDT, without
those ranges the kernel do not boot, i can dig more into these ranges if
required
Would you have an idea what these GPIOs are used for?
