This patch fixes null pointer dereference issue incurred
when ipp driver is enabled and Exynos drm driver is closed.
Non kms driver should register its own sub driver to setup necessary
resources, which is done by load(). So null pointer dereference
occurs when ipp driver is enabled and Exynos drm driver is closed
because ipp core device is registered after component_master_add_with_match
call.
This patch makes exynos_drm_device_subdrv_probe() to be called after all non

During a GPU reset we need to get pending page flip cleared out
since the ring contents are gone and flip will never complete
on its own. This used to work until the mmio vs. CS flip race
detection came about. That piece of code is looking for a
specific surface address in the SURFLIVE register, but as
a flip to that address may never happen the check may never
pass. So we should just skip the SURFLIVE and flip counter
checks when the GPU gets reset.
intel_display_handle_reset() tries to effectively complete
the flip anyway by calling .update_primary_plane(). But that
may not satisfy the conditions of the mmio vs. CS race
detection since there's no guarantee that a modeset didn't
sneak in between the GPU reset and intel_display_handle_reset().
Such a modeset will not wait for pending flips due to the ongoing GPU
reset, and then the primary plane updates performed by
intel_display_handle_reset() will already use the new surface
address, and thus the surface address the flip is waiting for
might never appear in SURFLIVE. The result is that the flip
will never complete and attempts to perform further page flips
will fail with -EBUSY.
During the GPU reset intel_crtc_has_pending_flip() will return
false regardless, so the deadlock with a modeset vs. the error
work acquiring crtc->mutex was avoided. And the reset_counter
check in intel_crtc_has_pending_flip() actually made this bug
even less severe since it allowed normal modesets to go through
even though there's a pending flip.
This is a regression introduced by me here:

Some radeon ASICs don't support all 64 address bits of MSIs despite
advertising support for 64-bit MSIs in their configuration space.
This breaks on systems such as IBM POWER7/8, where 64-bit MSIs can
be assigned with some of the high address bits set.
This makes use of the newly introduced "no_64bit_msi" flag in structure
pci_dev to allow the MSI allocation code to fallback to 32-bit MSIs
on those adapters.

Adding Alex's review tag. Patch to the driver is identical to the
reviewed one, I dropped the arch/powerpc hunk rewrote the subject
and cset comment.
In disable_outputs() we need to shut down the outgoing encoder, not the
incoming one (we have already swapped-state at this point). Without
this, we end up telling the driver to crtc->dpms(OFF) without first
encoder->dpms(OFF), and that makes some hw quite unhappy.

The Shared Memory Pool (SMP) has its own limitation, features and
state. Some examples are:
- the number of Memory Macro Block (MMB) and their size
- the number of lines that can be fetched
- the state of MMB currently allocated
- the computation of number of blocks required per plane
- client IDs ...
In order to avoid private data to be overwritten by other modules,
let's make these private to the SMP module.
Some of these depend on the hardware configuration, let's add them
to the mdp5_config struct.
In some hw configurations, some MMBs are statically tied to RGB
pipes and cannot be re-allocated dynamically. This change
introduces the concept of MMB static usage and makes sure that
dynamic MMB requests are dimensioned accordingly.
A note on passing a pipe pointer, instead of client IDs:
Client IDs are SMP-related information. Passing PIPE information
to SMP lets SMP module to find out which SMP client(s) are used.
This allows the SMP module to access the PIPE pointer, which can
be used for FIFO watermark configuration.
By the way, even though REG_MDP5_PIPE_REQPRIO_FIFO_WM_* registers
are part of the PIPE registers, their functionality is to reflect
the behavior of the SMP block. These registers access is now
restricted to the SMP module.

For mdp5, the irqs of hdmi/eDP/dsi0/dsi1 blocks get routed through the
mdp block. In order to decouple hdmi/eDP/etc, register an irq domain
in mdp5. When hdmi/dsi/etc are used with mdp4, they can directly setup
their irqs in their DT nodes as normal. When used with mdp5, instead
set the mdp device as the interrupt-parent, as in:
mdp: qcom,mdss_mdp@fd900000 {
compatible = "qcom,mdss_mdp";
interrupt-controller;
#interrupt-cells = <1>;
...
};
hdmi: qcom,hdmi_tx@fd922100 {
compatible = "qcom,hdmi-tx-8074";
interrupt-parent = <&mdp>;
interrupts = <8 0>; /* MDP5_HW_INTR_STATUS.INTR_HDMI */
...
};
There is a slight awkwardness, in that we cannot disable child irqs
at the mdp level, they can only be cleared in the child block. So
you must not use threaded irq handlers in the child. I'm not sure
if there is a better way to deal with that.

encoder->type can change underneath us and doesn't need to reflect
actual hw state (since we don't construct it from hw state like
e.g. encoder->crtc crtc->config).
And this can indeed happen:
1) Boot with plugged-in hdmi screen. Since we only set ->type in the
probe functions this means we won't detect any infoframes since
type is still unkown.
2) First probe sets type to HDMI.
3) If the first modeset now does _not_ happen on the HDMI pipe with
infoframes encoder->get_config suddenly sees infoframes and the
state checker gets angry.
Fix this by only relying on actual hw state when figuring out whether
the ddi port is in hdmi mode and sends infoframes.
