drm/msm/dp: unregister audio driver during unbind
while binding the code always registers a audio driver, however there
is no corresponding unregistration done in unbind. This leads to multiple
redundant audio platform devices if dp_display_bind and dp_display_unbind
happens multiple times during startup. On X13s platform this resulted in
6 to 9 audio codec device instead of just 3 codec devices for 3 dp ports.
Fix this by unregistering codecs on unbind.

drm/msm/dp: Return IRQ_NONE for unhandled interrupts
If our interrupt handler gets called and we don't really handle the
interrupt then we should return IRQ_NONE. The current interrupt
handler didn't do this, so let's fix it.
NOTE: for some of the cases it's clear that we should return IRQ_NONE
and some cases it's clear that we should return IRQ_HANDLED. However,
there are a few that fall somewhere in between. Specifically, the
documentation for when to return IRQ_NONE vs. IRQ_HANDLED is probably
best spelled out in the commit message of commit
d9e4ad5badf4 ("Document
that IRQ_NONE should be returned when IRQ not actually handled"). That
commit makes it clear that we should return IRQ_HANDLED if we've done
something to make the interrupt stop happening.
The case where it's unclear is, for instance, in dp_aux_isr() after
we've read the interrupt using dp_catalog_aux_get_irq() and confirmed
that "isr" is non-zero. The function dp_catalog_aux_get_irq() not only
reads the interrupts but it also "ack"s all the interrupts that are
returned. For an "unknown" interrupt this has a very good chance of
actually stopping the interrupt from happening. That would mean we've
identified that it's our device and done something to stop them from
happening and should return IRQ_HANDLED. Specifically, it should be
noted that most interrupts that need "ack"ing are ones that are
one-time events and doing an "ack" is enough to clear them. However,
since these interrupts are unknown then, by definition, it's unknown
if "ack"ing them is truly enough to clear them. It's possible that we
also need to remove the original source of the interrupt. In this
case, IRQ_NONE would be a better choice.
Given that returning an occasional IRQ_NONE isn't the absolute end of
the world, however, let's choose that course of action. The IRQ
framework will forgive a few IRQ_NONE returns now and again (and it
won't even log them, which is why we have to log them ourselves). This
means that if we _do_ end hitting an interrupt where "ack"ing isn't
enough the kernel will eventually detect the problem and shut our
device down.

drm/msm/dsi: Fix DSI index detection when version clash occurs
Currently, we allow for MAX_DSI entries in io_start to facilitate for
MAX_DSI number of DSI hosts at different addresses. The configuration
is matched against the DSI CTRL hardware revision read back from the
component. We need a way to resolve situations where multiple SoCs
with different register maps may use the same version of DSI CTRL. In
preparation to do so, make msm_dsi_config a 2d array where each entry
represents a set of configurations adequate for a given SoC.
This is totally fine to do, as the only differentiating factors
between same-version-different-SoCs configurations are the number of
DSI hosts (1 or 2, at least as of today) and the set of base registers.
The regulator setup is the same, because the DSI hardware is the same,
regardless of the SoC it was implemented in.
In addition to that, update the matching logic such that it will loop
over VARIANTS_MAX variants, making sure they are all taken into account.

The DP AUX interrupt handling was a bit of a mess.
* There were two functions (one for "native" transfers and one for
"i2c" transfers) that were quite similar. It was hard to say how
many of the differences between the two functions were on purpose
and how many of them were just an accident of how they were coded.
* Each function sometimes used "else if" to test for error bits and
sometimes didn't and again it was hard to say if this was on purpose
or just an accident.
* The two functions wouldn't notice whether "unknown" bits were
set. For instance, there seems to be a bit "DP_INTR_PLL_UNLOCKED"
and if it was set there would be no indication.
* The two functions wouldn't notice if more than one error was set.
Let's fix this by being more consistent / explicit about what we're
doing.
By design this could cause different handling for AUX transfers,
though I'm not actually aware of any bug fixed as a result of
this patch (this patch was created because we simply noticed how odd
the old code was by code inspection). Specific notes here:
1. In the old native transfer case if we got "done + wrong address"
we'd ignore the "wrong address" (because of the "else if"). Now we
won't.
2. In the old native transfer case if we got "done + timeout" we'd
ignore the "timeout" (because of the "else if"). Now we won't.
3. In the old native transfer case we'd see "nack_defer" and translate
it to the error number for "nack". This differed from the i2c
transfer case where "nack_defer" was given the error number for
"nack_defer". This 100% can't matter because the only user of this
error number treats "nack defer" the same as "nack", so it's clear
that the difference between the "native" and "i2c" was pointless
here.
4. In the old i2c transfer case if we got "done" plus any error
besides "nack" or "defer" then we'd ignore the error. Now we don't.
5. If there is more than one error signaled by the hardware it's
possible that we'll report a different one than we used to. I don't
know if this matters. If someone is aware of a case this matters we
should document it and change the code to make it explicit.
6. One quirk we keep (I don't know if this is important) is that in
the i2c transfer case if we see "done + defer" we report that as a
"nack". That seemed too intentional in the old code to just drop.
After this change we will add extra logging, including:
* A warning if we see more than one error bit set.
* A warning if we see an unexpected interrupt.
* A warning if we get an AUX transfer interrupt when shouldn't.
It actually turns out that as a result of this change then at boot we
sometimes see an error:
[drm:dp_aux_isr] *ERROR* Unexpected DP AUX IRQ 0x01000000 when not busy
That means that, during init, we are seeing DP_INTR_PLL_UNLOCKED. For
now I'm going to say that leaving this error reported in the logs is
OK-ish and hopefully it will encourage someone to track down what's
going on at init time.
One last note here is that this change renames one of the interrupt
bits. The bit named "i2c done" clearly was used for native transfers
being done too, so I renamed it to indicate this.

drm/msm/dpu: Move TE setup to prepare_for_kickoff()
Currently, DPU will enable TE during prepare_commit(). However, this
will cause a crash and reboot to sahara when trying to read/write to
register in get_autorefresh_config(), because the core clock rates
aren't set at that time.
This used to work because phys_enc->hw_pp is only initialized in mode
set [1], so the first prepare_commit() will return before any register
read/write as hw_pp would be NULL.
However, when we try to implement support for INTF TE, we will run into
the clock issue described above as hw_intf will *not* be NULL on the
first prepare_commit(). This is because the initialization of
dpu_enc->hw_intf has been moved to dpu_encoder_setup() [2].
To avoid this issue, let's enable TE during prepare_for_kickoff()
instead as the core clock rates are guaranteed to be set then.
Depends on: "Implement tearcheck support on INTF block" [3]

drm/msm: Implement fbdev emulation as in-kernel client
Move code from ad-hoc fbdev callbacks into DRM client functions
and remove the old callbacks. The functions instruct the client
to poll for changed output or restore the display. The DRM core
calls both, the old callbacks and the new client helpers, from
the same places. The new functions perform the same operation as
before, so there's no change in functionality.
Replace all code that initializes or releases fbdev emulation
throughout the driver. Instead initialize the fbdev client by a
single call to msm_fbdev_setup() after msm has registered its
DRM device. As in most drivers, msm's fbdev emulation now acts
like a regular DRM client.
The fbdev client setup consists of the initial preparation and the
hot-plugging of the display. The latter creates the fbdev device
and sets up the fbdev framebuffer. The setup performs display
hot-plugging once. If no display can be detected, DRM probe helpers
re-run the detection on each hotplug event.
A call to drm_dev_unregister() releases the client automatically.
No further action is required within msm. If the fbdev framebuffer
has been fully set up, struct fb_ops.fb_destroy implements the
release. For partially initialized emulation, the fbdev client
reverts the initial setup.
