Hi Jani,
The end goal was already achieve by the advice you gave the DRM_DP_AUX_CHARDEV.
I just like to extend my knowledge into DRM such as a scenario having a kernel version that doesn't have the DRM_DP_AUX_CHARDEV yet. Would it possible to implement specific DRM_DP_AUX_CHARDEV to it.
Thanks,
John

Try 'git grep DRM_DP_AUX_CHARDEV' in your kernel git repo, and see how
it affects conditional compilation.
This list isn't kernel development 101.
You still didn't say what your end goal is. Forget everything about DP
AUX and the chardev and so on, just tell us what you're trying to
achieve. Maybe you're asking about X, but you really want to know about
Y.

Jani.
