Experimentally have found PV on hvs4 reports fifo full
error with expected settings and does not with one less
This appears as:
[drm:drm_atomic_helper_wait_for_flip_done] *ERROR* [CRTC:82:crtc-3] flip_done timed out
with bit 10 of PV_STAT set "HVS driving pixels when the PV FIFO is full"

The vc4_plane_atomic_async_update function assigns twice in a row the
src_h field in the drm_plane_state structure to the same value. Remove
the second one.

We introduced the BCM2711 support to the vc4 HDMI controller with 5.10,
but this was lacking any of the interrupts of the CEC controller so we
have to deal with the backward compatibility.
Do so by simply ignoring the CEC setup if the DT doesn't have the
interrupts property.

The HDMI controller found in the BCM2711 has an external interrupt
controller for the CEC and hotplug interrupt shared between the two
instances.
Let's add a variant flag to register a single interrupt handler and
deals with the interrupt handler setup, or two interrupt handlers
relying on an external irqchip.

The BCM2711 has two different interrupt sources to transmit and receive
CEC messages, provided through an external interrupt chip shared between
the two HDMI interrupt controllers.
The rest of the CEC controller is identical though so we need to change
a bit the code organisation to share the code as much as possible, yet
still allowing to register independent handlers.

While the BCM2835 had the CEC clock derived from the HSM clock, the
BCM2711 has a dedicated parent clock for it.

As part of the enable sequence we might change the HSM clock rate if the
pixel rate is different than the one we were already dealing with.
On the BCM2835 however, the CEC clock derives from the HSM clock so any
rate change will need to be reflected in the CEC clock divider to output
40kHz.

The CEC clock divider needs to output a frequency of 40kHz from the HSM
rate on the BCM2835. The driver used to have a fixed frequency for it,
but that changed for the BCM2711 and we now need to compute it
dynamically to maintain the proper rate.

Currently we call cec_phys_addr_invalidate on a hotplug deassert.
That may be due to a TV power cycling, or an AVR being switched
on (and switching edid).
This makes CEC unusable since our controller wouldn't have a physical
address anymore.
Set it back up again on the hotplug assert.

The code prior to 311e305fdb4e ("drm/vc4: hdmi: Implement a register
layout abstraction") was relying on the fact that the register offset
was incremented by 4 for each readl call. That worked since the register
width is 4 bytes.
However, since that commit the HDMI_READ macro is now taking an enum,
and the offset doesn't increment by 4 but 1 now. Divide the index by 4
to fix this.

The hdmi reset got moved to a later point in the commit 9045e91a476b
("drm/vc4: hdmi: Add reset callback").
However, the reset now occurs after vc4_hdmi_cec_init and so tramples
the setup of registers like HDMI_CEC_CNTRL_1
This only affects pi0-3 as on pi4 the cec registers are in a separate
block

Commit 0a038c1c29a7 ("drm/vc4: Move LBM creation out of
vc4_plane_mode_set()") changed the LBM allocation logic from first
allocating the LBM memory for the plane to running mode_set,
adding a gap in the LBM, and then running the dlist allocation filling
that gap.
The gap was introduced by incrementing the dlist array index, but was
never checking whether or not we were over the array length, leading
eventually to memory corruptions if we ever crossed this limit.
vc4_dlist_write had that logic though, and was reallocating a larger
dlist array when reaching the end of the buffer. Let's share the logic
between both functions.

LBM base address is measured in units of pixels per cycle.
That is 4 for 2711 (hvs5) and 2 for 2708.
We are wasting 75% of lbm by indexing without the scaling.
But we were also using too high a size for the lbm resulting
in partial corruption (right hand side) of vertically
scaled images, usually at 4K or lower resolutions with more layers.
The physical RAM of LBM on 2711 is 8 * 1920 * 16 * 12-bit
(pixels are stored 12-bits per component regardless of format).
The LBM address indexes work in units of pixels per clock,
so for 4 pixels per clock that means we have 32 * 1920 = 60K

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.

If we're having two subsequent, non-blocking, commits on two different
CRTCs that share no resources, there's no guarantee on the order of
execution of both commits.
However, the second one will consider the first one as the old state,
and will be in charge of freeing it once that second commit is done.
If the first commit happens after that second commit, it might access
some resources related to its state that has been freed, resulting in a
use-after-free bug.
The standard DRM objects are protected against this, but our HVS private
state isn't so let's make sure we wait for all the previous FIFO users
to finish their commit before going with our own.
