If the source and sink support MSO, enable it during link training.
v4: Divide DRRS pixel clock by link count before M/N calculation
v3: Adjust timings, refer to splitter
v2: Limit MSO to pipe A using ->pipe_mask

In the case of MSO (Multi-SST Operation), the EDID contains the timings
for a single panel segment. We'll want to hide the fact from userspace,
and expose modes that span the entire display.
Don't modify the EDID, as the userspace should not use that for
modesetting, only modify the actual modes.
v3: Use pixel overlap if available.
v2: Rename intel_dp_mso_mode_fixup -> intel_edp_mso_mode_fixup

For starters, we expect the state to be zero, as we don't enable MSO
anywhere.

Add splitter configuration to crtc state, and read it where
supported. Also add splitter state dumping. The stream splitter will be
required for eDP MSO.
v4:
- Catch invalid splitter configuration (Uma)
v3:
- Convert segment timings to full panel timings.
- Refer to splitter instead of mso in crtc state.
- Dump splitter state.
v2: Add warning for mso being enabled on pipes other than A.

Currently if stream->signal is neither SIGNAL_TYPE_DISPLAY_PORT_MST or
SIGNAL_TYPE_DISPLAY_PORT then variable ret is uninitialized and this is
checked for > 0 at the end of the function. Ret should be initialized,
I believe setting it to zero is a correct default.

When we switch between SAGV on vs. off we need to reprogram all
plane wateramrks accordingly. Currently skl_wm_add_affected_planes()
totally ignores the SAGV watermark and just assumes we will use
the normal WM0.
Fix this by utilizing skl_plane_wm_level() which picks the
correct watermark based on use_sagv_wm. Thus we will force
an update on all the planes whose watermark registers need
to be reprogrammed.

Populate conn_state->max_bpc with something sensible from the start.
Otherwise it's possible that we get to compute_sink_pipe_bpp() with
max_bpc==0.
The specific scenario goes as follows:
1. Initial connector state allocated with max_bpc==0
2. Trigger a modeset on the crtc feeding the connector, without
actually adding the connector to the commit
3. drm_atomic_connector_check() is skipped because the
connector has not yet been added, hence conn_state->max_bpc
retains its current value
4. drm_atomic_helper_check_modeset() ->
drm_atomic_add_affected_connectors() -> the connector
is now part of the commit
5. compute_baseline_pipe_bpp() -> MISSING_CASE(max_bpc==0)
Note that pipe_bpp itself may not be populated on pre-g4x machines,
in which case we just fall back to max_bpc==8 and let .compute_config()
limit the resulting pipe_bpp further if necessary.

While reviewing patches for handling workarounds related to gen9 bc, Imre
from Intel discovered that we're using spt_hpd_irq_setup() on ICP+ PCHs
despite it being almost the same as icp_hpd_irq_setup(). Since we need to
be calling icp_hpd_irq_setup() to ensure that CML-S/TGP platforms function
correctly anyway, let's move platforms using PCH_ICP which aren't handled
by gen11_hpd_irq_setup() over to icp_hpd_irq_setup().

For Legacy S3 suspend/resume GEN9 BC needs to enable and
setup TGP PCH.
v2:
* Move Wa_14010685332 into it's own function - vsyrjala
* Add TODO comment about figuring out if we can move this workaround - imre
v3:
* Rename cnp_irq_post_reset() to cnp_display_clock_wa()
* Add TODO item mentioning we need to clarify which platforms this
workaround applies to
* Just use ibx_irq_reset() in gen8_irq_reset(). This code should be
functionally equivalent on gen9 bc to the code v2 added
* Drop icp_hpd_irq_setup() call in spt_hpd_irq_setup(), this looks to be
more or less identical to spt_hpd_irq_setup() minus additionally enabling
one port. Will update i915 to use icp_hpd_irq_setup() for ICP in a
separate patch.
v4:
* Revert Wa_14010685332 system list in comments to how it was before
* Add back HAS_PCH_SPLIT() check before calling ibx_irq_reset()

The ACPI scan capabilities is called from the intel-dspconfig as well
as the SOF/HDaudio drivers. This creates dependencies and randconfig issues
when HDaudio and SOF/SoundWire are not all configured as modules.
To simplify Kconfig dependencies between HDAudio, SoundWire, SOF and
intel-dspconfig, move the ACPI scan helpers to a dedicated
module. This follows the same idea as NHLT helpers which are already
handled as a dedicated module.
The only functional change is that the kernel parameter to filter
links is now handled by a different module, but that was only provided
for developers needing work-arounds for early BIOS releases.

It's often inconvenient to use BIO_MAX_PAGES due to min() requiring the
sign to be the same. Introduce bio_max_segs() and change BIO_MAX_PAGES to
be unsigned to make it easier for the users.

devices can trip SWIOTLB to bounce too much and crash the kernel
And a tiny fix to use proper APIs in drivers"

Pull RISC-V updates from Palmer Dabbelt:
"A handful of new RISC-V related patches for this merge window:
- A check to ensure drivers are properly using uaccess. This isn't
manifesting with any of the drivers I'm currently using, but may
catch errors in new drivers.
- Some preliminary support for the FU740, along with the HiFive
Unleashed it will appear on.
- NUMA support for RISC-V, which involves making the arm64 code
generic.
- Support for kasan on the vmalloc region.
- A handful of new drivers for the Kendryte K210, along with the DT
plumbing required to boot on a handful of K210-based boards.
- Support for allocating ASIDs.
- Preliminary support for kernels larger than 128MiB.
- Various other improvements to our KASAN support, including the
utilization of huge pages when allocating the KASAN regions.
We may have already found a bug with the KASAN_VMALLOC code, but it's
passing my tests. There's a fix in the works, but that will probably
miss the merge window.
