Hi,
You need a very strong justification to make an optional part of a driver to be "default y".
My opinion is that if the driver is built, everything should be built. This is what makes sense for distro's. It is only the embedded case where you want to trim down unneeded features where you might want to disable some parts. So 'default y' makes sense to me.
We don't set defaults for distro convenience.
Maybe use 'default DRM_MSM' so that it doesn't trigger the 'default y' filters people have?
Most people can figure that one out. ;) I don't have any automated filters.
After after further reviews, I agree with Rob. Display Port is required module as of now so it makes sense to keep 'default y'.
If it is required, then you don't need to have a Kconfig entry/symbol for it.
Kconfig makes driver flexible. Other moudles in the driver are also 'default y' such as DSI. I will let Rob guide us further on this as he is the maintainer.
