cgroup.h (therefore swap.h, therefore half of the universe)
includes bpf.h which in turn includes module.h and slab.h.
Since we're about to get rid of that dependency we need
to clean things up.
v2: drop the cpu.h include from cacheinfo.h, it's not necessary
and it makes riscv sensitive to ordering of include files.

When CONFIG_COMMON_CLOCK is disabled, the 8996 specific
phy code is left out, which results in a link failure:
ld: drivers/gpu/drm/msm/hdmi/hdmi_phy.o:(.rodata+0x3f0): undefined reference to `msm_hdmi_phy_8996_cfg'
This was only exposed after it became possible to build

Make COMMON_CLK a hard dependency for compile testing,
and simplify it a little based on that.

If you happened to try to access `/dev/drm_dp_aux` devices provided by
the MSM DP AUX driver too early at bootup you could go boom. Let's
avoid that by only allowing AUX transfers when the controller is
powered up.
Specifically the crash that was seen (on Chrome OS 5.4 tree with
relevant backports):
Kernel panic - not syncing: Asynchronous SError Interrupt
CPU: 0 PID: 3131 Comm: fwupd Not tainted 5.4.144-16620-g28af11b73efb #1

I did a little bit of tracing and found that:
* We register the AUX device very early at bootup.
* Power isn't actually turned on for my system until
hpd_event_thread() -> dp_display_host_init() -> dp_power_init()
* You can see that dp_power_init() calls dp_aux_init() which is where
we start allowing AUX channel requests to go through.
In general this patch is a bit of a bandaid but at least it gets us
out of the current state where userspace acting at the wrong time can
fully crash the system.
* I think the more proper fix (which requires quite a bit more
changes) is to power stuff on while an AUX transfer is
happening. This is like the solution we did for ti-sn65dsi86. This
might be required for us to move to populating the panel via the
DP-AUX bus.
* Another fix considered was to dynamically register / unregister. I
tried that at <https://crrev.com/c/3169431/3> but it got
ugly. Currently there's a bug where the pm_runtime() state isn't
tracked properly and that causes us to just keep registering more
and more.

If "data_lanes" property of the dsi output endpoint is missing in
the DT, num_data_lanes would be 0 by default, which could cause
dsi_host_attach() to fail if dsi->lanes is set to a non-zero value
by the bridge driver.
According to the binding document of msm dsi controller, the
input/output endpoint of the controller is expected to have 4 lanes.
So let's set num_data_lanes to 4 by default.

In commit 510410bfc034 ("drm/msm: Implement mmap as GEM object
function") we switched to a new/cleaner method of doing things. That's
good, but we missed a little bit.
Before that commit, we used to _first_ run through the
drm_gem_mmap_obj() case where `obj->funcs->mmap()` was NULL. That meant
that we ran:
vma->vm_flags |= VM_IO | VM_PFNMAP | VM_DONTEXPAND | VM_DONTDUMP;
vma->vm_page_prot = pgprot_writecombine(vm_get_page_prot(vma->vm_flags));
vma->vm_page_prot = pgprot_decrypted(vma->vm_page_prot);
...and _then_ we modified those mappings with our own. Now that
`obj->funcs->mmap()` is no longer NULL we don't run the default
code. It looks like the fact that the vm_flags got VM_IO / VM_DONTDUMP
was important because we're now getting crashes on Chromebooks that
use ARC++ while logging out. Specifically a crash that looks like this
(this is on a 5.10 kernel w/ relevant backports but also seen on a
5.15 kernel):

Let's add the two flags back in.
While we're at it, the fact that we aren't running the default means
that we _don't_ need to clear out VM_PFNMAP, so remove that and save
an instruction.
NOTE: it was confirmed that VM_IO was the important flag to fix the
problem I was seeing, but adding back VM_DONTDUMP seems like a sane
thing to do so I'm doing that too.

Add CRC support to DPU, which is currently not supported by
this driver. Only supports CRC for CRTC for now, but will extend support
to other blocks later on.
Changes in v2:
- Added kfree() calls for return paths in dpu_crtc_get_crc()
- Propogated error code for dpu_crtc_get_crc()
- Renamed skip_count
- Removed dpu_crtc_is_valid_crc_source()
- Removed wait for commit in dpu_crtc_set_crc_source()
- Moved crc_source from struct dpu_crtc to struct dpu_crtc_state
- Moved CRC register constants from dpu_hw_util.h to dpu_hw_lm.c

Based on the removal of the g_dp_display and the movement of the
priv->dp lookup into the DP code it's now possible to have multiple
DP instances.
In line with the other controllers in the MSM driver, introduce a
per-compatible list of base addresses which is used to resolve the
"instance id" for the given DP controller. This instance id is used as
index in the priv->dp[] array.
Then extend the initialization code to initialize struct drm_encoder for
each of the registered priv->dp[] and update the logic for associating
each struct msm_dp with the struct dpu_encoder_virt.
A new enum is introduced to document the connection between the
instances referenced in the dpu_intf_cfg array and the controllers in
the DP driver and sc7180 is updated.
Lastly, bump the number of struct msm_dp instances carries by priv->dp
to 3, the currently known maximum number of controllers found in a
Qualcomm SoC.

Functions in the DisplayPort code that relates to individual instances
(encoders) are passed both the struct msm_dp and the struct drm_encoder.
But in a situation where multiple DP instances would exist this means
that the caller need to resolve which struct msm_dp relates to the
struct drm_encoder at hand.
Store a reference to the struct msm_dp associated with each
dpu_encoder_virt to allow the particular instance to be associate with
the encoder in the following patch.

The msm_gem_new_impl() function cleans up after itself so there is no
need to call drm_gem_object_put(). Conceptually, it does not make sense
to call a kref_put() function until after the reference counting has
been initialized which happens immediately after this call in the
drm_gem_(private_)object_init() functions.
In the msm_gem_import() function the "obj" pointer is uninitialized, so
it will lead to a crash.

The debugfs code is provided an array of a single drm_connector. Then to
access the connector, the list of all connectors of the DRM device is
traversed and all non-DisplayPort connectors are skipped, to find the
one and only DisplayPort connector.
But as we move to support multiple DisplayPort controllers this will now
find multiple connectors and has no way to distinguish them.
Pass the single connector to dp_debug_get() and use this in the debugfs
functions instead, both to simplify the code and the support the
multiple instances.
