The rcar-du driver goes to great lengths to preserve device tree
backward compatibility for the LVDS encoders by patching old device
trees at runtime.
The last R-Car Gen2 platform was converted to the new bindings commit
edb0c3affe5214a2 ("ARM: dts: r8a7793: Convert to new LVDS DT bindings"),
in v4.17, and the last RZ/G1 platform converted in commit
6a6a797625b5fe85 ("ARM: dts: r8a7743: Convert to new LVDS DT bindings"),
in v5.0. Both are older than commit 58256143cff7c2e0 ("clk: renesas:
Remove R-Car Gen2 legacy DT clock support"), in v5.5, which removes
support for legacy bindings for clocks. The LVDS compatibility code is
thus not needed anymore. Drop it.

According to my investigation of the state of PCI
reset recently it's not working. The reason is
due to the fact the kernel PCI code rejects SBR
when there are more then one PF under same bridge
which we always have (at least AUDIO PF but usually
more) and that because SBR will reset all the PFS
and devices under the same bridge as you and you
cannot assume they support SBR.
Once we anble FLR support we can reenable this option as
FLR is doable on single PF and doens't have this
restriction.

Workstation application ANSA/META v21.1.4 get this error dmesg when
running CI test suite provided by ANSA/META:
[drm:amdgpu_gem_va_ioctl [amdgpu]] *ERROR* Couldn't update BO_VA (-16)
This is caused by:
1. create a 256MB buffer in invisible VRAM
2. CPU map the buffer and access it causes vm_fault and try to move
it to visible VRAM
3. force visible VRAM space and traverse all VRAM bos to check if
evicting this bo is valuable
4. when checking a VM bo (in invisible VRAM), amdgpu_vm_evictable()
will set amdgpu_vm->evicting, but latter due to not in visible
VRAM, won't really evict it so not add it to amdgpu_vm->evicted
5. before next CS to clear the amdgpu_vm->evicting, user VM ops
ioctl will pass amdgpu_vm_ready() (check amdgpu_vm->evicted)
but fail in amdgpu_vm_bo_update_mapping() (check
amdgpu_vm->evicting) and get this error log
This error won't affect functionality as next CS will finish the
waiting VM ops. But we'd better clear the error log by checking
the amdgpu_vm->evicting flag in amdgpu_vm_ready() to stop calling
amdgpu_vm_bo_update_mapping() later.
Another reason is amdgpu_vm->evicted list holds all BOs (both
user buffer and page table), but only page table BOs' eviction
prevent VM ops. amdgpu_vm->evicting flag is set only for page
table BOs, so we should use evicting flag instead of evicted list
in amdgpu_vm_ready().
The side effect of this change is: previously blocked VM op (user
buffer in "evicted" list but no page table in it) gets done
immediately.
v2: update commit comments.

The GPU reset function of raven2 is not maintained or tested, so it should be
very unstable.
Now the amdgpu_asic_reset function is added to amdgpu_pmops_suspend, which
causes the S3 test of raven2 to fail, so the asic_reset of raven2 is ignored
here.

[Why]
Found when running igt@kms_atomic.
Userspace attempts to do a TEST_COMMIT when 0 streams which calls
dc_remove_stream_from_ctx. This in turn calls link_enc_unassign
which ends up modifying stream->link = NULL directly, causing the
global link_enc to be removed preventing further link activity
and future link validation from passing.
[How]
We take care of link_enc unassignment at the start of
link_enc_cfg_link_encs_assign so this call is no longer necessary.
Fixes global state from being modified while unlocked.
