[GIT PULL] move ARM LCD display driver to auxdisplay

[GIT PULL] move ARM LCD display driver to auxdisplay

[Linus Walleij]

Hi ARM SoC guys,

these two patches move the ARM character LCD driver from
misc drivers to the auxdisplay subsystem where it belongs and
updates the defconfig for the RealView accordingly.

Please pull it into some cleanup branch in the ARM SoC
tree.

I tried to get some ACK from the auxdisplay maintainer but no
reaction.

Yours,
Linus Walleij

Auxdisplay is not a new framework, but rather a very old one.

It got introduced in 2.6.21, and only received a couple of drivers
since.

It seems to be quite redundant with fbdev deferred_io, which itself is
almost deprecated these days.

I'm holding off on this pull request for now then.

I'd certainly like to see the driver get moved out of drivers/misc,
let me know once there has been an agreement of where it should go.

Small problem for me, but Robin is submitting a brand new
auxdisplay driver:

That is a valid argument for moving cfag12864b* out to
drivers/video/* I guess, but it has nothing to do with this
driver whatsoever.

This driver has nothing to do with fbdev. Nothing at all.
It so not connected to any framebuffer.

This driver gets moved to auxdisplay to match the existing
LCD driver in drivers/auxdisplay/ks0108.c which is a similar
hardware, driving an LCD that likewise has nothing to do
with fbdev.

My understanding is that Tomi doesn't want any new fbdev drivers, so
I'm not sure this is the right place for those patches.

My bad, I thought all auxdisplay drivers were fbdev ones, but I was
wrong, obviously. And now, I don't really know what auxdisplay is
about anymore :)

Still, moving it to a "framework" that has been inactive for so long
(and you even mention it in your PR) doesn't seem like the right move.

I still think sorting the driver into the right bucket has a value.

When/if the Linux LCD support gets an upstream push they
will know where to put their stuff: here, and then common stuff
can be abstracted. With drivers floating around in misc the
situation is even worse. http://lcd-linux.sourceforge.net/

Hmm, that one looks like an fbdev driver, not an auxdisplay driver. But,
not relevant for this patch, of course.

I think this move makes sense. It's only moving a file to a directory
that at least mentions "display", not really moving it into a framework
(because there doesn't seem to be any).

The best would be if you volunteer to maintain it and bring

Thats fine. Would it suffice if I submit another patch adding myself
to the maintainers file?

That's half of it, if Miguel does not come back then his name
should be removed as the second step.

You also need to have an idea on a path to funnel accumulated
patches upstream to Torvalds. The recent patches to this
subsystem were funneled by Greg, so we should ask him how
he prefer to proceed.

Greg, what do you prefer?

I don't care :)

I can keep doing this, sending stuff to Linus through my char/misc tree,
or it can go through someone else's tree, it doesn't bother me...

Sure, I'd be glad to do so if that makes your life easier.  Either way
it's no real extra or less overall workload for me :)

First half is completed. I've added myself as maintainer for the
driver I've posted recently (HT16K33 LED CONTROLLER DRIVER).

According to MAINTAINERS, Miguel maintains:
 - CFAG12864B LCD DRIVER
 - CFAG12864BFB LCD FRAMEBUFFER DRIVER
 - KS0108 LCD CONTROLLER DRIVER
 - AUXILIARY DISPLAY DRIVERS

AFAIK, I should not be judge in Miguels case.

@linus: I'll send my patches to Greg if you agree on this.

If patches come in for these drivers and Miguel still seem to be fallen
off the face of the earth I think you should ACK/merge patches for
these too, but deal with it when it happens.
