Can you explain why tinydrm is not putting its panel drivers in

I guess everybody knows except me, it's usually like that :(

I am anyways working on a driver for Ilitek 9322 that I want
to land in drivers/gpu/drm/panel. Here is the last iteration:
Yeah I got sidetracked. OK I will get to it now.

There are some similarities with the code I'm seeing here
but I believe they are essentially different. But it will be hard
to share code if you put the driver in the tinydrm framework.

I guess you have also seen:

Stefano Babic who wrote the backlight driver is available for
reviewing, so includ him in follow-ups (added to To: line).

I'm putting you on CC as I'm rewriting it a bit after the DT
maintainers review, will try to repost ASAP.
