drm/panel-simple: add Gopher 2b LCD panel
The Gopher 2b LCD panel is used in Gopher 2b handhelds.
It's simple panel with NewVision NV3047 driver, but SPI lines are not
connected. It has no specific name, since it's unique to that handheld.

ce13c78fa9 drm/i915: Disable gpu relocations
Media userspace was the last userspace to still use them, and they
converted now too:

144020c377

This means no reason anymore to make relocations faster than they've
been for the first 9 years of gem. This code was added in

commit 7dd4f6729f
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Fri Jun 16 15:05:24 2017 +0100

    drm/i915: Async GPU relocation processing

Furthermore there's pretty strong indications it's buggy, since the
code to use it by default as the only option had to be reverted:

commit ad5d95e4d5
Author: Dave Airlie <airlied@redhat.com>
Date:   Tue Sep 8 15:41:17 2020 +1000

    Revert "drm/i915/gem: Async GPU relocations only"

This code just disables gpu relocations, leaving the garbage
collection for later patches and more importantly, much less confusing
diff. Also given how much headaches this code has caused in the past,
letting this soak for a bit seems justified.

05b78d291d drm/i915/xehp: Changes to ss/eu definitions
Xe_HP no longer has "slices" in the same way that old platforms did.
There are new concepts (gslices, cslices, mslices) that apply in various
contexts, but for the purposes of fusing slices no longer exist and we
just have one large pool of dual-subslices (DSS) to work with.
Furthermore, the meaning of the DSS fuse is inverted compared to past
platforms --- it now specifies which DSS are enabled rather than which
ones are disabled.

e053163660 drm/i915/dg2: Add forcewake table
The DG2 forcewake table is very similar to the one used by XeHP SDV (and
both platforms are even presented as a single table in the bspec).  For
the most part DG2 starts using a few additional ranges that were
'reserved' on XeHP SDV and stops using some others.  However there is a
single range (0xd800-0xd87f) that needs to be handled differently
between the two platforms (it needs GT wake on XeHP SDV, but render wake
on DG2) so unless we want to wake both domains (which could waste power)
or define new types of forcewake domains for this special case we need
to have separate tables for the two platforms.  Let's define the ranges
for both platforms with a parameterized macro so that we don't actually
need to duplicate everything in the code.

It should be fine for DG2 to re-use the Xe_HP shadow register list so we
can continue to use the 'xehpsdv' MMIO write functions and don't need to
spin up a separate DG2 instance.

216d56c5da drm/i915/guc/rc: Setup and enable GuCRC feature
This feature hands over the control of HW RC6 to the GuC.
GuC decides when to put HW into RC6 based on it's internal
busyness algorithms.

GuCRC needs GuC submission to be enabled, and only
supported on Gen12+ for now.

When GuCRC is enabled, do not set HW RC6. Use a H2G message
to tell GuC to enable GuCRC. When disabling RC6, tell GuC to
revert RC6 control back to KMD. KMD is still responsible for
enabling everything related to Coarse Power Gating though.

233624e0d5 drm/i915: Apply CMTG clock disabling WA while DPLL0 is enabled
CI test results/further experiments show that the workaround added in

commit 573d7ce4f6 ("drm/i915/adlp: Add workaround to disable CMTG clock gating")

can be applied only while DPLL0 is enabled. If it's disabled the
TRANS_CMTG_CHICKEN register is not accessible. Accordingly move the WA
to DPLL0 HW state sanitization and enabling.

This fixes an issue where the WA won't get applied (and a WARN is thrown
due to an unexpected value in TRANS_CMTG_CHICKEN) if the driver is
loaded without DPLL0 being enabled: booting without BIOS enabling an
output with this PLL, or reloading the driver.

While at it also add a debug print for the unexpected register value.

de59865042 drm/amdgpu: Fix out-of-bounds read when update mapping
If one GTT BO has been evicted/swapped out, it should sit in CPU domain.
TTM only alloc struct ttm_resource instead of struct ttm_range_mgr_node
for sysMem.

Now when we update mapping for such invalidated BOs, we might walk out
of bounds of struct ttm_resource.

Three possible fix:
1) Let sysMem manager alloc struct ttm_range_mgr_node, like
ttm_range_manager does.
2) Pass pages_addr to update_mapping function too, but need memset
pages_addr[] to zero when unpopulate.
3) Init amdgpu_res_cursor directly.

bug is detected by kfence.

82929a2140 drm/i915: Correct SFC_DONE register offset
The register offset for SFC_DONE was missing a '0' at the end, causing
us to read from a non-existent register address.  We only use this
register in error state dumps so the mistake hasn't caused any real
problems, but fixing it will hopefully make the error state dumps a bit
more useful for debugging.

DG1 and XE_PLD platforms has Audio MMIO/VERBS lies in PG0 power
well. Adjusting the power domain accordingly to
POWER_DOMAIN_AUDIO_MMIO for audio detection and
POWER_DOMAIN_AUDIO_PLAYBACK for audio playback.

While doing this it requires to use POWER_DOMAIN_AUDIO_MMIO
power domain instead of POWER_DOMAIN_AUDIO in crtc power domain mask
and POWER_DOMAIN_AUDIO_PLAYBACK with intel_display_power_{get, put}
to enable/disable display audio codec power.

It will save the power in use cases when DP/HDMI connectors
configured with PIPE_A without any audio playback.

Fix it up by mocking enough of drm_device and drm_plane so we can call
drm_plane_enable_fb_damage_clips() to make the new check happy.

Since there's a lot of duplicated mock code already copy-pasted into
each test I've also refactored this a bit to trim it down.
