We already have __drm_atomic_helper_connector_reset() and
__drm_atomic_helper_plane_reset(), extend this to crtc as well.
This will allow us to set default values in the crtc_state, without
having to do it in each driver separately.
Of all drivers that need conversion, only nouveau is done in this
commit, because it wrote its own __drm_atomic_helper_crtc_reset(),
clashing with the drm core.

With the previous patch drm_crtc_find will return NULL when the crtc
isn't in our lease, which will then disable the plane/connector. No
longer an issue since the lessor can't escape their lease terms
anymore, but not quite great semantics yet either.
Catch this and return -EACCES, so that at least evil test cases have a
better chance of making sure the kernel works correctly.

We need this to make sure lessees can only connect their
plane/connectors to crtc objects they own. And note that this is
irrespective of whether the lessor is atomic or not, lessor cannot
prevent lessees from enabling atomic.

If userspace doesn't enable universal planes, then we automatically
add the primary and cursor planes. But for universal userspace there's
no such check (and maybe we only want to give the lessee one plane,
maybe not even the primary one), hence we need to check for the
implied plane.
v2: don't forget setcrtc ioctl.
v3: Still allow disabling of the crtc in SETCRTC.

Not exactly sure what's the aim here, but the canonical nil object has
id == 0, we don't use negative object ids for anything. Plus all
object_id are valided by the object_idr, there's nothing we need to do
on top of that ENOENT check a bit further down.

Fix the order of lane, port parameters passed to the register macro.
Note that this was already partly fixed by commit
37fc7845df7b6 ("drm/i915: Call MG_DP_MODE() macro with the right parameters order")

unnecessary redirection via an array.

drm: Turn off Legacy Context Functions
The context functions are not used by the i915 driver and should not
be used by modeset drivers. These driver functions contain several bugs
and security holes. This change makes these functions optional can be
turned on by a setting, they are turned off by default for modeset
driver with the exception of the nouvea driver that may require them with
an old version of libdrm.
The previous attempt was

Revert "drm: mark context support as a legacy subsystem"
v2: remove returns from void function, and formatting (Daniel Vetter)
v3:
- s/Nova/nouveau/ in the commit message, and add references to the
previous attempts
- drop the part touching the drm hw lock, that should be a separate
patch.

Print out debug messages with correct device name.
As for this, this patch adds device pointer to exynos_drm_ipp structure,
and in case of exynos_drm_ipp_task structure, replace drm_device pointer
with device one. This will make each ipp driver to print out debug
messages with correct device name.

Add device pointer to vidi_context and remove platform_device pointer.
It doesn't need for vidi_context to contain platform_device object.
Instead, this patch makes this driver more simply by replacing platform_device
pointer with device one.

This time around it is a bunch of cleanup and fixes, expanding gpu
"zap" shader support (so we can take the GPU out of secure mode on
boot) to a6xx, and small UABI extension to support robustness (see
mesa MR 673).

drm-misc-next for v5.2:
UAPI Changes:
- Document which feature flags belong to which command in virtio_gpu.h
- Make the FB_DAMAGE_CLIPS available for atomic userspace only, it's useless for legacy.
Cross-subsystem Changes:
- Add device tree bindings for lg,acx467akm-7 panel and ST-Ericsson Multi Channel Display Engine MCDE
- Add parameters to the device tree bindings for tfp410
- iommu/io-pgtable: Add ARM Mali midgard MMU page table format
- dma-buf: Only do a 64-bits seqno compare when driver explicitly asks for it, else wraparound.
- Use the 64-bits compare for dma-fence-chains
Core Changes:
- Make the fb conversion functions use __iomem dst.
- Rename drm_client_add to drm_client_register
- Move intel_fb_initial_config to core.
- Add a drm_gem_objects_lookup helper
- Add drm_gem_fence_array helpers, and use it in lima.

- Converts bochs to use the simple display type.
- Small fixes to sun4i, tinydrm, ti-fp410.

[why]
When DMCU interrupts x86, it leads to undefined phy programming
[how]
expand dmcu interface to support new PHY lock and unlock commands
if DMCU FW doesn't support these commands, they fail silently so its okay

[Why]
Starting with DCN1, the input_pixel_processor (ipp) struct has been
replaced by dpp struct (part of DAL3.1 SW architecture change).
Need to update logic to handle cases where ipp is never allocated.
[How]
Only skip cursor position programming if both ipp and dpp resources
are NULL.
