[RFC,v4,0/7] Add FS035VG158 panel

Message

Hello there,

This RFC introduces support for the FS035VG158 LCD panel, cleaning up
the nv3052c driver on the way and documentating existing panel code.

This patch series is at a bit of a standstill: I have gotten feedback
that it should instead use the Leadtek LTK035C5444T panel init sequence
instead of Fascontek's provided sequence which is almost identical.

I don't feel comfortable providing a patch that does this unless someone
can explain why the changes Fascontek have made aren't critical.

I would like feedback to know if this is a blocker for this patch set,
or otherwise what needs to be done to get it merged.

John.

v3 -> v4:
- Mark panel_regs_len as unsigned

v2 -> v3:
- Dropped patches that add extra sleep time

v1 -> v2:
- Fixed a variable declaration style error
- Cleaned up device tree yaml
