cec_read() is non-atomic in the presence of other I2C bus transactions
to the same device. This presents a problem when we add support for
the TDA9950 CEC engine part - both drivers can be trying to access the
device.
Avoid the inherent problems by switching to i2c_transfer() instead,
which allows us to perform more than one bus transaction atomically.
As this means we will be using I2C transactions rather than SMBUS, we
have to check that the host supports I2C functionality.

Some TDA998x contain several different I2C devices - there is the HDMI
encoder, and there is a TDA9950 CEC engine. These two share the same
interrupt signal.
In order to allow a driver for the CEC engine to work, we need to be
able to share the interrupt with the CEC driver, so convert the handler
and registration to allow this to happen.

Disabling the pre-filter block of the TDA998x saves 40mW and the colour
conversion block saves 15mW. As we always disable these two blocks, we
can power these sections of the chip down to save 55mW of unnecessary
power consumption.

The CEA 861B specification indicates the situations when we are able to
send each infoframe based on the version of the EDID's CEA extension.
Update the tda998x driver to follow the CEA specification wrt sending
of infoframes.
Since we only support the generation of AVI version 2, this limits us
to CEA extension version 3, so we treat CEA extension version 2 as
CEA 861 (no infoframes, no audio.)

Avoid a race between programming audio and an in-progress mode set.
A mode set is complex, and disables the ability to send infoframes
to the sink, and is disruptive to audio - we have to mute the audio
FIFO while doing a mode set.
If an attempt is made to start up the audio side, we will undo the
audio FIFO mute before the mode set has completed.
Move the lock so that we prevent audio interfering with an in-progress
mode set.

As priv->audio_params can now be changed at run time, we need to be more
careful about how we deal with a mode set. We must take the audio lock
while checking if there's a valid audio configuration.
However, it's slightly worse than that - during mode set, we mute the
audio, and it must not be unmuted until we have finished the mode set.
It is possible that the audio side may start while a mode set is in
progress, so take the audio_mutex lock around the whole mode setting
procedure.

Connectors shouldn't be registered until the rest of the whole device
is set up, so that consistent state is presented to userspace.
As such, remove the calls to drm_connector_register() and
drm_connector_unregister() from tda998x, as these are now handled by
drm_dev_(un)register() itself.
To work with this change, the mali-dp and hdlcd bind and unbind
sequences have to be reordered, to ensure that the componentised
encoder/connector is bound before drm_dev_register() registers all
connectors. Similarly, the device must be unregistered before the
component is unbound.
Altogether, this allows other drivers using tda998x to be
de-midlayered, and to have less racy initialisation of their components.
Splitting this commit into three (one per driver) isn't possible without
intermediate breakage, so it is all squashed together here.

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.

The driver has been converted to use drm_bridge instead of
drm_i2c_slave_encoder. We can now move it to the bridge folder.
Create a separate folder since we already have a couple of files and
expect more when we support audio and ADV7533.
Rename the driver to adv7511_drv.c. This will come in handy later
when the driver module will need to be built from multiple object
files.

We don't want to use the old i2c slave encoder interface anymore.
Remove that and make the i2c driver create a drm_bridge entity instead.
Converting to bridges helps because the kms drivers don't need to
exract encoder slave ops from this driver and use it within their
own encoder/connector ops.
The driver now creates its own connector when a kms driver attaches
itself to the bridge. Therefore, kms drivers don't need to create
their own connectors anymore.
The old encoder slave ops are now used by the new bridge and connector
entities.
The of_node member in drm_bridge is accessible only when CONFIG_OF is
enabled. The driver anyway only works only when OF is available. Make
the driver depend on OF in its Kconfig.

Choose between atomic or non atomic connector dpms helper. If tda998x
is connected to a drm driver that does not support atomic modeset
calling drm_atomic_helper_connector_dpms() causes a crash when the
connectors atomic state is not initialized. The patch implements a
driver specific connector dpms helper that calls
drm_atomic_helper_connector_dpms() if driver supports DRIVER_ATOMIC
and otherwise it calls the legacy drm_helper_connector_dpms().

An encoder is associated with a connector by the DRM core as a result of
setting up a configuration. Drivers using the atomic or legacy helpers
should never set up this link, even if it is a static one.
While at it, try to catch this kind of error in the future by adding a
WARN_ON() in drm_mode_connector_attach_encoder(). Note that this doesn't
cover all the cases, since drivers could set this up after attaching.
Drivers that use the atomic helpers will get a warning later on, though,
so hopefully the two combined cover enough to help people avoid this in
the future.
