We can have various combinations of 64b and 32b address space, ie. 64b
CPU but 32b display and gpu, or 64b CPU and GPU but 32b display. So
best to decouple the device iova's from mmap offset.

If fb dimensions are larger than what can be scanned out, but the src
dimensions are not, the hw can still handle this. So clip.

If the bottom-most layer is not fullscreen, we need to use the BASE
mixer stage for solid fill (ie. MDP5_CTL_BLEND_OP_FLAG_BORDER_OUT). The
blend_setup() code pretty much handled this already, we just had to
figure this out in _atomic_check() and assign the stages appropriately.
Also fix the case where there are zero enabled planes, where we also
need to enable BORDER_OUT.

into drm-next
These updates:
* improve the robustness of the driver wrt races
* improve the compliance for sending infoframes and audio
* re-organise the function order in the driver to group like functions
together. (This unfortunately causes a conflict with the change in
drm-misc, but it should be trivial to solve, although it looks more
scarey than it really is - sfr has already sent two reports about
this, one earlier today.)
* simplify tda998x_audio_get_eld and DPMS handling
* power down sections of the chip that we never use
* add some initial preparation for supporting the CEC driver

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 naming of tda998x_encoder_set_config() is a left-over from when
TDA998x was a slave encoder. Since this is part of the initialisation,
drop the _encoder from the name, and move it near tda998x_bind().

Check for audio support by the attached sink by consulting the EDID
prior to enabling audio over the TMDS link. We must consult the EDID
after calling drm_helper_probe_single_connector_modes(), as this can
use an override EDID, or load a replacement EDID.

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.
