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:

identical lines left from the original patch and some of the ideas
have come from there.

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.

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.

Commit 6833d26ef8 ("drm: tda998x: Fix EDID read timeout on HDMI
connect") used a weak scheme to try and delay reading EDID on a HDMI
connect event. It is weak because delaying the notification of a
hotplug event does not stop userspace from trying to read the EDID
within the 100ms delay.
The solution provided here solves this issue:
* When a HDMI connection event is detected, mark a blocking flag for
EDID reads, and start a timer for the delay.
* If an EDID read is attempted, and the blocking flag is set, wait
for the blocking flag to clear.
* When the timer expires, clear the blocking flag and wake any thread
waiting for the EDID read.

The EDID read code waits for the read completion interrupt to occur
using wait_event_interruptible(). The condition passed to the macro
reads I2C registers. This results in sleeping with the task state set
to TASK_INTERRUPTIBLE, triggering a WARN_ON() introduced in commit
8eb23b9f35 ("sched: Debug nested sleeps").
Fix this by reworking the EDID read code. Instead of checking whether
the read is complete through I2C reads, handle the interrupt registers
in the interrupt handler and update a new edid_read flag accordingly. As
a side effect both the IRQ and polling code paths now process the
interrupt sources through the same code path, simplifying the code.

The I2C address for the TDA9989 and TDA19989 is fixed at 0x34 but the
two LSBs of the TDA19988's address are set by two configuration pins
on the chip. Irrespective of the chip, the associated CEC peripheral's
I2C address is based upon the main I2C address.
This patch avoids any special handling required to support systems that
contain multiple TDA19988 devices on the same I2C bus.

This builds upon the previous set of fixes which were pulled on 6th July.
Included in this set are:
- an update from Jean-Francois to add the missing reg documentation entry
to the device tree documentation.
- conversion of the tda998x driver to the component helpers.
* 'tda998x-devel' of git://ftp.arm.linux.org.uk/~rmk/linux-cubox:
drm/i2c: tda998x: add component support
drm/i2c: tda998x: allow re-use of tda998x support code

Add component helper support to the tda998x driver. This permits the
TDA998x to be declared as a separate device in device tree, and bound
at the appropriate moment with a co-operating card driver.
The existing slave_encoder interfaces are kept while there are existing
users of it in order to prevent regressions.

Re-jig the TDA998x code so that we separate the functionality from the
drm slave encoder implementation. In several places, this is pretty
clearly the correct thing to do, because we can avoid repetitively
having to convert from the drm_encoder to the TDA998x private
structure, particularly with the driver internal functions.
The main motivation behind this change is to allow the code to be
re-used with a standard drm_encoder and drm_connector implementation
based on the component helpers, rather than the slave_encoder system.
The addition of this will be in the following patch.
We keep the slave_encoder interface as there are existing users of
this; we need to give them time to convert and test.

Currently tda998x_encoder_destroy() calls cec_write() and reg_clear(),
as part of the release procedure. Such calls need to access the I2C bus
and therefore, we need to call them before drm_i2c_encoder_destroy()
which unregisters the I2C device.
This commit moves the latter so it's done afterwards.

This is C standard hair-splitting, but afaict
- sum will be promoted to signed int in computation since
uint8_t fits
- signed overflow is undefined.
No we need to add up an awful lot of bytes to actually make it
overflow. But I guess the real risk is gcc spotting this and going
bananas. Fix this by simply using unsigned in to force all computations
to use the well-defined unsigned behaviour.
Spotted by coverity.

that some critical registers are left containing values which affect
the device operation. One such case encountered is the VIP output
mux register. This defaults to 0x24 on powerup, but other drivers may

This driver is a KMS-based driver and requires a compatible nouveau

This driver requires firmware files not available in this kernel tree,
interested parties can find them via the nouveau project git archive.
This driver is reverse engineered, and is in no way supported by nVidia.
Support for nearly the complete range of nvidia hw from nv04->g80 (nv50)
