[PATCH 0/3] Introduce ClockworkPi CWD686 DRM panel driver

[Max Fierke]

The ClockworkPi DevTerm (all models) uses a 6.86" IPS display
of unknown provenance, which uses the Chipone ICNL9707 IC driver[1].

The display panel I have has two model numbers: TXW686001 and WTL068601G,
but cannot find any manufacturer associated with either, so opting for the
ClockworkPi model number.

This driver is based on the GPL-licensed driver released by ClockworkPi[1],
authored by Pinfan Zhu, with some additional cleanup, rotation support,
and display sleep re-enabling done by me.
