f5a9ed867c drm/sun4i: Fix component unbinding and component master deletion
For our component-backed driver to be properly removed, we need to
delete the component master in sun4i_drv_remove and make sure to call
component_unbind_all in the master's unbind so that all components are
unbound when the master is.

02b92adbe3 drm/sun4i: Set device driver data at bind time for use in unbind
Our sun4i_drv_unbind gets the drm device using dev_get_drvdata.
However, that driver data is never set in sun4i_drv_bind.

Set it there to avoid getting a NULL pointer at unbind time.

71adf60f0a drm/sun4i: Add missing drm_atomic_helper_shutdown at driver unbind
A call to drm_atomic_helper_shutdown is required to properly release
the internal references taken by the core and avoid warnings about

61b51fb51c drm/tegra: gem: Fix CPU-cache maintenance for BO's allocated using get_pages()
The allocated pages need to be invalidated in CPU caches. On ARM32 the
DMA_BIDIRECTIONAL flag only ensures that data is written-back to DRAM and
the data stays in CPU cache lines. While the DMA_FROM_DEVICE flag ensures
that the corresponding CPU cache lines are getting invalidated and nothing
more, that's exactly what is needed for a newly allocated pages.

This fixes randomly failing rendercheck tests on Tegra30 using the
Opentegra driver for tests that use small-sized pixmaps (10x10 and less,
i.e. 1-2 memory pages) because apparently CPU reads out stale data from
caches and/or that data is getting evicted to DRAM at the time of HW job
execution.

b8f9d7f37b drm/rockchip: shutdown drm subsystem on shutdown
As explained by Robin Murphy:
> the IOMMU shutdown disables paging, so if the VOP is still
> scanning out then that will result in whatever IOVAs it was using now going
> straight out onto the bus as physical addresses.

We had a more radical approach before in commit
7f3ef5dedb ("drm/rockchip: Allow driver to be shutdown on reboot/kexec")
but that resulted in new warnings and oopses on shutdown on rk3399
chromeos devices.

So second try is resurrecting Vicentes shutdown change which should
achieve the same result but in a less drastic way.

This reverts commit 8059add047.

for a node being master because something succeeds where it failed

Apply the Linus rule, revert early and try again, we don't break

bd53280ef0 drm/drv: Fix incorrect resolution of merge conflict
Commit f06ddb5309 ("BackMerge v5.1-rc5 into drm-next") incorrectly
resolved a merge conflict related to a patch having been merged twice:
- commit 3f04e0a6cf ("drm: Fix drm_release() and device unplug")
  introduced as a standalone fix via drm-fixes branch,
- commit 1ee57d4d75 ("drm: Fix drm_release() and device unplug")
  applied as patch 1/2 of a series on drm-next branch.
That incorrect resolution of the conflict effectively reverted a change
introduced to drivers/gpu/drm/drm_drv.c by patch 2/2 of that series -
commit ba3bf37e15 ("drm/drv: drm_dev_unplug(): Move out drm_dev_put()
call").  Fix it.

The reason is the contiguous buffer exceeds the default maximum segment

linux/dma-mapping.h.  Fix this by providing our own segment size, which
is set to 2GiB to cover the window found in MMUv1 GPUs.

While the implicit dev_priv is removed from the IRQ initialization
helpers, we didn't get rid of them in the macro callers. Doing that
should be very simple now.

9d9523d8c1 drm/i915: add GEN2_ prefix to the I{E, I, M, S}R registers
This discussion started because we use token pasting in the
GEN{2,3}_IRQ_INIT and GEN{2,3}_IRQ_RESET macros, so gen2-4 passes an
empty argument to those macros, making the code a little weird. The
original proposal was to just add a comment as the empty argument, but
Ville suggested we just add a prefix to the registers, and that indeed
sounds like a more elegant solution.

Now doing this is kinda against our rules for register naming since we
only add gens or platform names as register prefixes when the given
gen/platform changes a register that already existed before. On the
other hand, we have so many instances of IIR/IMR in comments that
adding a prefix would make the users of these register more easily
findable, in addition to make our token pasting macros actually
readable. So IMHO opening an exception here is worth it.

macros take the register name in the 'type' argument. But gen2 only
has one set of registers, so there's really no need to specify the
type. This commit removes the type argument and uses the registers
directly instead of passing them through variables.

68eb49b140 drm/i915: refactor the IRQ init/reset macros
The whole point of having macros here is for the token pasting
necessary to automatically have IMR, IIR and IER selected. We don't
really need or want all the inlining that happens as a consequence.
The good thing about the current code is that it works regardless of
the relative offsets between these registers (they change after gen4,
with the usual VLV/CHV exceptions).

One thing which we can do is to split the logic of what we do with
imr/ier/iir to functions separate from the macros that pick them.
That's what we do in this commit. This allows us to get rid of the
gen8 duplicates and also all the inlining:

76356a966e drm: aspeed: Clean up Kconfig options
The GFX IP is inside of the ASPEED BMC SoC so there is little use
enabling it on a kernel that does not support ASPEED.

When building with COMPILE_TEST the architecture many not have CMA
support, so to avoid breaking the build we only select these options if
the architecture supports the contiguous allocator.

I suspect the DRM_PANEL came from a cut/paste error.

ac07157828 drm/i915/gvt: addressed guest GPU hang with HWS index mode
with the introduce of "switch to use HWS indices rather than address",
guest GPU hang observed when running workloads which will update the
seqno to the real HW HWSP, not vitural GPU HWSP and then cause GPU hang.

this patch is to revoke index mode in PIPE_CTRL and MI_FLUSH_DW and
patch guest GPU HWSP address value to these commands.

c856dbc887 drm/i915: Nuke drm_crtc_state and use intel_atomic_state instead
This is one of the patches to start replacing drm pointers
and use the intel_atomic_state and intel_crtc to derive
the necessary intel state variables required for the intel
modeset functions.

v3:
* Remove the unwanted newline (Ville)
v2:
* Flip the function arguments (Ville)
* Remove some remaining instances of drm pointers (Ville)
* Use old_crtc_state and new_crtc_state (Ville)

f5c58ba18a drm/i915: Restore correct bxt_ddi_phy_calc_lane_lat_optim_mask() calculation
We are no longer calling bxt_ddi_phy_calc_lane_lat_optim_mask() when
intel{hdmi,dp}_compute_config() succeeds, and instead only call it
when those fail. This is fallout from the bool->int
.compute_config() conversion which failed to invert the return
value check before calling bxt_ddi_phy_calc_lane_lat_optim_mask().
Let's just replace it with an early bailout so that it's harder
to miss.

This restores the correct latency optim setting calculation
(which could fix some real failures), and avoids the
MISSING_CASE() from bxt_ddi_phy_calc_lane_lat_optim_mask()
after intel{hdmi,dp}_compute_config() has failed.

5aae7832d1 drm/i915: Do not enable FEC without DSC
Currently we enable FEC even when DSC is no used. While that is
theoretically valid supposedly there isn't much of a benefit from
this. But more importantly we do not account for the FEC link
bandwidth overhead (2.4%) in the non-DSC link bandwidth computations.
So the code may think we have enough bandwidth when we in fact
do not.

f55be0be5b drm/amd/display: Add profiling tools for bandwidth validation
[Why]
We used this change to investigate the performance of bandwidth validation,
it will be useful to have if we need to investigate further.

[How]
We use performance counter tick numbers to profile performance, they live
at dc->debug.bw_val_profile (set .enable in debugger to turn on measuring).

c14a005c16 drm/amd/display: Relax requirements for CRTCs to be enabled
[Why]
As long as we have at least one non-cursor plane enabled on a CRTC then
the CRTC itself can remain enabled.

This will allow for commits where there's an overlay plane enabled but
no primary plane enabled.

[How]
Remove existing primary plane fb != NULL checks and replace them with
the new does_crtc_have_active_plane helper.

This will be called from atomic check when validating the CRTC.

Since the primary plane state can now potentially be NULL we'll need
to guard for that when accessing it in some of the cursor logic.
