The changeset contains a number of cleanups, changed semantics of
init_panel() callback, which allows to simplify getting of panel
properties from panel device tree node, and a handling of optional
"enable-gpios" panel property, the latter is described in
display/panel/panel-dpi.txt device tree binding documentation, but
it has been unsupported by the ARM CLCD driver.

As you may have seen Tomi has stepped down as FBDEV maintainer and
this subsystem is now orphaned.

I guess Andrew Morton merges patches for it in this case, he usually does.

But what we should actually do is create a new DRM driver for CLCD
in drivers/gpu/drm/arm/clcd*

It's maybe not a small undertaking :(

But in case you're interested in the job, I will pitch in and test the result
on all ARM reference designs plus Nomadik.

A DRM driver for it would probably be a good idea, but dealing with all
the weird and wonderful connection arrangements may not be that easy...
