There is a new version of DMC available for CNL.
The release notes mentions:
1. Fix for the issue where DC_STATE was getting enabled
even when disabled by driver causing data corruption
v2: Since the firmware is merged to linux-firmware.git,
add MODULE_FIRMWARE.
v3: rebased. Correct commit message(Jani)

git://git.armlinux.org.uk/~rmk/linux-arm into drm-next
This series builds upon the set of fixes previously submitted to move
Armada DRM closer to atomic modeset. We're nowhere near yet, but this
series helps to get us closer by unifying some of the differences
between the primary and overlay planes.
New features added allows userspace to disable the primary plane if
overlay is full screen and there's nothing obscuring the colorkey -
this saves having to fetch an entire buffer containing nothing but
colorkey when displaying full screen video.

drm-next
Highlights this time:
1. Fix for a nasty Kconfig dependency chain issue from Philipp.
2. Occlusion query buffer address added to the cmdstream validator by
Christian.
3. Fixes and cleanups to the job handling from me. This allows us to
turn on the GPU performance profiling added in the last cycle.
It is also prep work for hooking in the DRM GPU scheduler, which I hope
to land for the next cycle.

In some iommu, e.g. swiotlb, the available space can be quite limited.
So we employ a trial-and-error approach to seeing if our large
contiguous chunks can fit, and if that fails we try again with smaller
chunks after trying to free our own lazily allocated blobs. As we use a
trial-and-error approach, we do not want dma_map_sg() to emit a WARN of
its own accord, we want to gracefully report the error back to the caller
instead.
Note that our noisy culprit, swiotlb, doesn't honour the flag, yet.

Display WA #1183 was recently added to workaround
"Failures when enabling DPLL0 with eDP link rate 2.16
or 4.32 GHz and CD clock frequency 308.57 or 617.14 MHz
(CDCLK_CTL CD Frequency Select 10b or 11b) used in this
enabling or in previous enabling."
This workaround was designed to minimize the impact only
to save the bad case with that link rates. But HW engineers
indicated that it should be safe to apply broadly, although
they were expecting the DPLL0 link rate to be unchanged on
runtime.
We need to cover 2 cases: when we are in fact enabling DPLL0
and when we are just changing the frequency with small
differences.
This is based on previous patch by Rodrigo Vivi with suggestions
from Ville Syrjälä.

We were calling enable_irq on bind, where it was already enabled previously
by the IRQ helper. Additionally, dev->irq is not set correctly until after
postinstall and so was always zero here, triggering a warning in 4.15.
Fix both by moving the enable to the power management resume path, where we
know there was a previous disable invocation during suspend.

The Additional Data Struct (ADS) contains objects that are required by
GuC post FW load and are not necessarily submission-only. Even with
submission disabled we may require something inside the ADS, so it
makes more sense for them to be always created.
Similarly, we need to access GuC logs and even if GuC submission
is disabled, to debug issues with GuC loading or with whatever we're using
GuC for.

The original bindings were the generic "ilitek,ili9225-2.2in-176x220"
because I could not find a datasheet. However, after some more research,
I finally found one, so the actual vendor and model name are now known.
This previous bindings have not made it to the mainline kernel yet, so
