Pull devicetree updates from Rob Herring:
"Bindings:
- Enable dtc "interrupt_provider" warnings for binding examples. Fix
the warnings in fsl,mu-msi and ti,sci-inta due to this.
- Convert zii,rave-sp-wdt, zii,rave-sp-pwrbutton, and
altr,fpga-passive-serial to DT schema format
- Add some documentation on the different forms of YAML text blocks
which are a constant source of review comments
- Fix some schema errors in constraints for arrays
- Add compatibles for qcom,sar2130p-pdc and onnn,adt7462
DT core:
- Allow overlay kunit tests to run CONFIG_OF_OVERLAY=n
- Add some warnings on deprecated address handling
- Rework early_init_dt_scan() so the arch can pass in the phys
address of the DTB as __pa() is not always valid to use. This fixes
a warning for arm64 with kexec.
- Add and use some new DT graph iterators for iterating over ports
and endpoints
- Rework reserved-memory handling to be sized dynamically for fixed
regions
- Optimize of_modalias() to avoid a strlen() call
- Constify struct device_node and property pointers where ever
possible"

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all platform drivers below drivers/video/fbdev to use .remove(),
with the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.
While touching these files, make indention of the struct initializer
consistent in several files.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The drm/omap driver was fixed to correct an issue where using a
divider of 32 breaks the DSS despite the TRM stating 32 is a valid
number. Through experimentation, it appears that 31 works, and
it is consistent with the value used by the drm/omap driver.
This patch fixes the divider for fbdev driver instead of the drm.

The omapfb driver fails to build after commit 23c35f48f5fb
("pinctrl: remove include file from <linux/device.h>") because it
relies on the <linux/pinctrl/consumer.h> and <linux/seq_file.h>
being pulled in by the <linux/device.h> header implicitly.
Include these headers explicitly to avoid the build failures.

Copy the content of video/omapdss.h to a new (video/omapfb_dss.h) header

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.
