drm: vc4: Fix pixel-wrap issue with DVP teardown
Adjust the DVP enable/disable sequence to avoid a pixel getting stuck
in an internal, non resettable FIFO within PixelValve when changing
HDMI resolution.

The blank pixels features of the DVP can prevent signals back to
pixelvalve causing it to not clear the FIFO. Adjust the ordering
and timing of operations to ensure the clear signal makes it through to
pixelvalve.

drm/vc4: hdmi: Limit noise when deferring snd card registration
We don't want to print an error message each time
devm_snd_soc_register_card() returns -EPROBE_DEFER, the function will
most likely succeed some time in the future, once the missing resources
are available. So use dev_err_probe(), which will redirect the messages
to the debug log level in such case.

drm/vc4: hdmi: Set HD_CTL_WHOLSMP and HD_CTL_CHALIGN_SET
Symptom is random switching of speakers when using multichannel.

Repeatedly running speakertest -c8 occasionally starts with
channels jumbled. This is fixed with HD_CTL_WHOLSMP.

The other bit looks beneficial and apears harmless in testing so
I'd suggest adding it too.

Documentation says: HD_CTL_WHILSMP_SET
Wait for whole sample. When this bit is set MAI transmit will start
only when there is at least one whole sample available in the fifo.

Documentation says: HD_CTL_CHALIGN_SET
Channel Align When Overflow. This bit is used to realign the audio
channels in case of an overflow.
If this bit is set, after the detection of an overflow, equal
amount of dummy words to the missing words will be written to fifo,
filling up the broken sample and maintaining alignment.

In order to access the HDMI controller, we need to make sure the HSM
clock is enabled. If we were to access it with the clock disabled, the
CPU would completely hang, resulting in an hard crash.

Since we have different code path that would require it, let's move that
clock enable / disable to runtime_pm that will take care of the
reference counting for us.

If the of_get_named_gpio_flags call fails in vc4_hdmi_bind, we jump to

pm_runtime_disable and put_device on the DDC device.

We just retrieved the DDC device, so the latter is definitely justified.
However at that point we still haven't called pm_runtime_enable, so the
call to pm_runtime_disable is not supposed to be there.

drm/vc4: hdmi: Check and warn if we can't reach 4kp60 frequencies
In order to reach the frequencies needed to output at 594MHz, the
firmware needs to be configured with the appropriate parameters in the

Let's detect it at bind time, warn the user if we can't, and filter out

drm/vc4: Unify PCM card's driver_name
User-space ALSA matches a card's driver name against an internal list of
aliases in order to select the correct configuration for the system.
When the driver name isn't defined, the match is performed against the
card's name.

With the introduction of RPi4 we now have two HDMI ports with two
distinct audio cards. This is reflected in their names, making them
different from previous RPi versions. With this, ALSA ultimately misses
the board's configuration on RPi4.

In order to avoid this, set "card->driver_name" to "vc4-hdmi"
unanimously.

drm/vc4: hdmi: Don't poll for the infoframes status on setup
The infoframes are sent at a regular interval as a data island packet,
so we don't need to wait for them to be sent when we're setting them up.

However, we do need to poll when we're enabling since the we can't
update the packet RAM until it has been sent.

Let's add a boolean flag to tell whether we want to poll or not to
support both cases.

drm/vc4: hdmi: Disable Wifi Frequencies
There's cross-talk on the RPi4 between the 2.4GHz channels used by the WiFi
chip and some resolutions, most notably 1440p at 60Hz.

In such a case, we can either reject entirely the mode, or lower slightly
the pixel frequency to remove the overlap. Let's go for the latter.

The HDMI controller cannot go above a certain pixel rate limit depending on
the generations, but that limit is only enforced in mode_valid at the
moment, which means that we won't advertise modes that exceed that limit,
but the userspace is still free to try to setup a mode that would.

Implement atomic_check to make sure we check it in that scenario too.

drm/vc4: hdmi: Avoid sleeping in atomic context
When running the trigger hook, ALSA by default will take a spinlock, and
thus will run the trigger hook in atomic context.

However, our HDMI driver will send the infoframes as part of the trigger
hook, and part of that process is to wait for a bit to be cleared for up to
100ms. To be nicer to the system, that wait has some usleep_range that
interact poorly with the atomic context.

There's several ways we can fix this, but the more obvious one is to make
ALSA take a mutex instead by setting the nonatomic flag on the DAI link.
That doesn't work though, since now the cyclic callback installed by the
dmaengine helpers in ALSA will take a mutex, while that callback is run by
dmaengine's virt-chan code in a tasklet where sleeping is not allowed
either.

Given the delay we need to poll the bit for, changing the usleep_range for
a udelay and keep running it from a context where interrupts are disabled
is not really a good option either.

However, we can move the infoframe setup code in the hw_params hook, like
is usually done in other HDMI controllers, that isn't protected by a
spinlock and thus where we can sleep. Infoframes will be sent on a regular
basis anyway, and since hw_params is where the audio parameters that end up
in the infoframes are setup, this also makes a bit more sense.

  get DC support, nouveau got a bump in displayport support with common
  code extraction from i915.

  moduleparams which you've acked, and a virtio common code tree that

drm/vc4: hdmi: Implement finer-grained hooks
In order to prevent some pixels getting stuck in an unflushable FIFO on
bcm2711, we need to enable the HVS, the pixelvalve (the CRTC) and the HDMI
controller (the encoder) in an intertwined way, and with tight delays.

However, the atomic callbacks don't really provide a way to work with
either constraints, so we need to roll our own callbacks so that we can
provide those guarantees.

Since those callbacks have been implemented and called in the CRTC code, we
can just implement them in the HDMI driver now.

drm/vc4: hdmi: Use clk_set_min_rate instead
The HSM clock needs to be running at 101% the pixel clock of the HDMI
controller, however it's shared between the two HDMI controllers, which
means that if the resolutions are different between the two HDMI
controllers, and the lowest resolution is on the second (in enable order)
controller, the first HDMI controller will end up with a smaller than
expected clock rate.

Since we don't really need an exact frequency there, we can simply change
the minimum rate we expect instead.

drm/vc4: hdmi: Adjust HSM clock rate depending on pixel rate
The HSM clock needs to be setup at around 101% of the pixel rate. This
was done previously by setting the clock rate to 163.7MHz at probe time and
only check in mode_valid whether the mode pixel clock was under the pixel
clock +1% or not.

However, with 4k we need to change that frequency to a higher frequency
than 163.7MHz, and yet want to have the lowest clock as possible to have a
decent power saving.

Let's change that logic a bit by setting the clock rate of the HSM clock
to the pixel rate at encoder_enable time. This would work for the
BCM2711 that support 4k resolutions and has a clock that can provide it,
but we still have to take care of a 4k panel plugged on a BCM283x SoCs
that wouldn't be able to use those modes, so let's define the limit in
the variant.

drm/vc4: hdmi: Implement a register layout abstraction
The HDMI controllers found in the BCM2711 have most of the registers
reorganized in multiple registers areas and at different offsets than
previously found.

The logic however remains pretty much the same, so it doesn't really make
sense to create a whole new driver and we should share the code as much as
possible.

Let's implement some indirection to wrap around a register and depending on
the variant will lookup the associated register on that particular variant.

drm/vc4: hdmi: Retrieve the vc4_hdmi at unbind using our device
The unbind function needs to retrieve a vc4_hdmi structure pointer through
the struct device that we're given since we want to support multiple HDMI
controllers.

However, our optional ASoC support doesn't make that trivial since it will
overwrite the device drvdata if we use it, but obviously won't if we don't
use it.

Let's make sure the fields are at the proper offset to be able to cast
between the snd_soc_card structure and the vc4_hdmi structure
transparently so we can support both cases.

drm/vc4: hdmi: Add container_of macros for encoders and connectors
Whenever the code needs to access the vc4_hdmi structure from a DRM
connector or encoder, it first accesses the drm_device associated to the
connector, then retrieve the drm_dev private data which gives it a
pointer to our vc4_dev, and will finally follow the vc4_hdmi pointer in
that structure.

That will also give us some trouble when having multiple controllers,
but now that we have our encoder and connector structures that are part
of vc4_hdmi, we can simply call container_of on the DRM connector or
encoder and retrieve the vc4_hdmi structure directly.
