The A33 pipeline also has a component called DRC. Even though its exact
features and programming model is not known (or documented), it needs to
be clocked for the pipeline to carry the video signal all the way.
Add a minimal driver for it that just claim the needed resources for the
pipeline to operate properly.

Register ASoC HDMI codec for audio functionality and adds device tree
binding for audio configuration.
With the registered HDMI codec the tda998x node can be used like a
regular codec node in ASoC card configurations. HDMI audio info-frame
and audio stream header is generated by the ASoC HDMI codec. The codec
also applies constraints for available sample-rates based on Edid Like
Data from the display. The device tree binding document has been
updated [1].
Part of this patch has been inspired by Jean Francoise's "drm/i2c: tda998x:
Add support of a DT graph of ports"-patch [2]. There may still be some
identical lines left from the original patch and some of the ideas
have come from there.

Add "blue-and-red-wiring"-device tree property and update devicetree
binding document.
The red and blue components are reversed between 24 and 16 bit modes
on am335x LCDC output pins. To get 24 RGB format the red and blue
wires has to be crossed and this in turn causes 16 colors output to be
in BGR format. With straight wiring the 16 color is RGB and 24 bit is
BGR.
The new property describes whether the red and blue wires are crossed
or not. If the property is not present or its value is not recognized
the legacy mode is assumed. The legacy configuration supports RGB565,
RGB888 and XRGB8888 formats. However, depending on wiring, the red and
blue colors are swapped in either 16 or 24-bit color modes.
For more details see section 3.1.1 in AM335x Silicon Errata:

Just for the struct drm_mode_object base class. The header file was
already partially extracted to help untangle the include loops.
v2:
- Also move the generic get/set property ioctls. At first this seemed
like a bad idea since it requires making drm_mode_crtc_set_obj_prop
non-static. But eventually that will get split away too (like
the connector version already is) for both crtc and planes. Hence I
reconsidered.
- drm_mode_object.[hc] instead of drm_modeset.[hc], which requires
renaming the drm_modeset.h header I already started building up.
This is more consistent (matches the name of the main structure),
and I want to be able to use drm_modeset.[hc] for the basic modeset
init/cleanup functionality like drm_mode_config_init.

There's not much point in kerneldoc if it's not included:
- It won't show up in the pretty html pages.
- The comments itself won't get parsed, which means 0day won't pick up
changes, resulting in stale docs fast.
Also, uapi really should be core, not helpers, so move drm_blend.c to
that. That also means that the zpos normilize function loses it's
helper status (and we might as well call it always). For that,
EXPORT_SYMBOL. Just spotted while integrating docs and noticing that
one was missing.
With sphinx there's really no excuse any more to not build the docs
and make sure it's all nice!

Pulls in quite a lot of connector related structures (cmdline mode,

sense.

It's super confusing that new drivers need to be marked with
DRIVER_MODESET when really it means DRIVER_MODERN. Much better to
invert the meaning and rename it to something that's suitably
off-putting.
Since there's over 100 places using DRIVER_MODESET we need to roll out
this change without a flag day.

Pull more block fixes from Jens Axboe:
"As mentioned in the pull the other day, a few more fixes for this
round, all related to the bio op changes in this series.
Two fixes, and then a cleanup, renaming bio->bi_rw to bio->bi_opf. I
wanted to do that change right after or right before -rc1, so that
risk of conflict was reduced. I just rebased the series on top of
current master, and no new ->bi_rw usage has snuck in"
* 'for-linus' of git://git.kernel.dk/linux-block:

Pull drm zpos property support from Dave Airlie:
"This tree was waiting on some media stuff I hadn't had time to get a
stable branchpoint off, so I just waited until it was all in your tree
first.
It's been around a bit on the list and shouldn't affect anything
outside adding the generic API and moving some ARM drivers to using
it"
* tag 'drm-for-v4.8-zpos' of git://people.freedesktop.org/~airlied/linux:
drm: rcar: use generic code for managing zpos plane property
drm/exynos: use generic code for managing zpos plane property
drm: sti: use generic zpos for plane
drm: add generic zpos property
Since commit 63a4cc2486, bio->bi_rw contains flags in the lower
portion and the op code in the higher portions. This means that
old code that relies on manually setting bi_rw is most likely
going to be broken. Instead of letting that brokeness linger,
rename the member, to force old and out-of-tree code to break
at compile time instead of at runtime.
No intended functional changes in this commit.

First off, the intention of this pull is to declare that I'll be the
binfmt_misc maintainer (mainly on the grounds of you touched it last,
it's yours). There's no MAINTAINERS entry, but get_maintainers.pl
will now finger me.
The update itself is to allow architecture emulation containers to
function such that the emulation binary can be housed outside the
container itself. The container and fs parts both have acks from
relevant experts.
The change is user visible. To use the new feature you have to add an
F option to your binfmt_misc configuration. However, the existing
tools, like systemd-binfmt work with this without modification.

itself. The container and fs parts both have acks from relevant

To use the new feature you have to add an F option to your binfmt_misc

From the docs:
"The usual behaviour of binfmt_misc is to spawn the binary lazily when
the misc format file is invoked. However, this doesn't work very well
in the face of mount namespaces and changeroots, so the F mode opens
the binary as soon as the emulation is installed and uses the opened
image to spawn the emulator, meaning it is always available once
installed, regardless of how the environment changes"

Instead of a ramoops-specific node, use a child node of /reserved-memory.
This requires that of_platform_device_create() be explicitly called
for the node, though, since "/reserved-memory" does not have its own
"compatible" property.
