Pull fbdev updates from Bartlomiej Zolnierkiewicz:
"Mostly small fixes and cleanups for fb drivers (the biggest updates
are for udlfb and pxafb drivers). This also adds deferred console
takeover support to the console code and efifb driver.
Summary:
- add support for deferred console takeover, when enabled defers
fbcon taking over the console from the dummy console until the
first text is displayed on the console - together with the "quiet"
kernel commandline option this allows fbcon to still be used
together with a smooth graphical bootup (Hans de Goede)
- improve console locking debugging code (Thomas Zimmermann)
- copy the ACPI BGRT boot graphics to the framebuffer when deferred
console takeover support is used in efifb driver (Hans de Goede)
- update udlfb driver - fix lost console when the user unplugs a USB
adapter, fix the screen corruption issue, fix locking and add some
performance optimizations (Mikulas Patocka)
- update pxafb driver - fix using uninitialized memory, switch to
devm_* API, handle initialization errors and add support for
lcd-supply regulator (Daniel Mack)
- add support for boards booted with a DeviceTree in pxa3xx_gcu
driver (Daniel Mack)
- rename omap2 module to omap2fb.ko to avoid conflicts with omap1
driver (Arnd Bergmann)
- enable ACPI-based enumeration for goldfishfb driver (Yu Ning)
- fix goldfishfb driver to make user space Android code use 60 fps
(Christoffer Dall)
- print big fat warning when nomodeset kernel parameter is used in
vgacon driver (Lyude Paul)
- remove VLA usage from fsl-diu-fb driver (Kees Cook)
- misc fixes (Julia Lawall, Geert Uytterhoeven, Fredrik Noring,
Yisheng Xie, Dan Carpenter, Daniel Vetter, Anton Vasilyev, Randy
Dunlap, Gustavo A. R. Silva, Colin Ian King, Fengguang Wu)
- misc cleanups (Roman Kiryanov, Yisheng Xie, Colin Ian King)"

Pointer 'in' is being assigned but is never used hence it is
redundant and can be removed.

At over 4000 #includes, <linux/platform_device.h> is the 9th most
#included header file in the Linux kernel. It does not need
<linux/mod_devicetable.h>, so drop that header and explicitly add
<linux/mod_devicetable.h> to source files that need it.
4146 #include <linux/platform_device.h>
After this patch, there are 225 files that use <linux/mod_devicetable.h>,
for a reduction of around 3900 times that <linux/mod_devicetable.h>
does not have to be read & parsed.
225 #include <linux/mod_devicetable.h>
This patch was build-tested on 20 different arch-es.
It also makes these drivers SubmitChecklist#1 compliant.

Copy the content of video/omapdss.h to a new (video/omapfb_dss.h) header
file and convert the omapfb drivers to use this new file.
The new header file is needed to complete the separation of omapdrm and
omapfb implementation of DSS.

This patch makes a copy of the omapdss driver and the omap panel &
encoder drivers for omapfb. The purpose is to separate omapdrm and
omapfb drivers from each other.
Note that this patch only does a direct copy of the files without any
other modifications. The files are not yet used.
The original files are in:
drivers/video/fbdev/omap2/dss/
drivers/video/fbdev/omap2/displays-new/
Here's a more detailed explanation about this and the following patches,
from the introduction mail of the patch series:
A short background on the current status. We have the following
entities:
* omapdss, located in drivers/video/fbdev/omap2/dss/. This is a driver for the
display subsystem IPs used on OMAP (and related) SoCs. It offers only a
kernel internal API, and does not implement anything for fbdev or drm.
* omapdss panels and encoders, located in
drivers/video/fbdev/omap2/displays-new/. These are panel and external encoder
drivers, which use APIs offered by omapdss driver. These also don't implement
anything for fbdev or drm.
* omapdrm, located in drivers/gpu/drm/omapdrm/. This is a drm driver, which
uses omapdss and the panel/encoder drivers to operate the hardware.
* omapfb, located in drivers/video/fbdev/omap2/omapfb/. This is an fbdev
driver, which uses omapdss and the panel/encoder drivers to operate the
hardware.
* omap_vout, located in drivers/media/platform/omap/. This is a v4l2 driver,
which uses omapdss and omapfb to implement a v4l2 API for the video overlays.
So, on the top level, we have either omapdrm, or omapfb+omap_vout. Both of
those use the same low level drivers. Without going to the historical details
why the architecture is like that, I think it's finally time to change that.
The situation with omapfb+omap_vout is that it still works, but no new features
have been added for a long time, and I want to keep it working as it's still
being used. At some point in the future I'd like to remove omapfb and
omap_vout altogether.
Omapdrm, on the other hand, is being actively developed. Sharing the low level
parts with omapfb makes that development more difficult than it should be. It
also "hides" half of the development, as everything happening in the low level
parts resides under fbdev directory, not in the drm directory.
I've been wanting to clean this up for a long time, but I haven't figured out a
very good way to do it. I still haven't, but here's the best way I have come up
with.
This series makes a full copy of the low level parts, omapdss and panel/encoder
drivers. Both omapfb+omap_vout and omapdrm will have their own versions. The
copy omapfb+omap_vout get is a new copy, and the copy that omapdrm gets is just
the current files moved. This way git will associate the omapdrm version with
the old files.
The omapfb+omap_vout versions won't be touched unless there are some big issues
there.
The omapdrm versions can be refactored and cleaned up, as the omapfb support
code is no longer needed. We can perhaps also merge omapdss and omapdrm into
the same kernel module.
This series only does the copy, and the absolutely necessary parts. No further
cleanups are done yet.
