50aec9665e drm/xe: Use ordered WQ for G2H handler 
System work queues are shared, use a dedicated work queue for G2H
processing to avoid G2H processing getting block behind system tasks.

9fbd0adbcb drm/xe/mocs: Add debugfs node to dump mocs 
This is useful to check mocs configuration. Tests/Tools can use
this debugfs entry to get mocs info.

v2: Address review comments. Change debugfs output style similar
to pat debugfs. (Lucas De Marchi)

v3: rebase.

v4: Address review comments. Use function pointer inside ops
struct. Update Test-with links. Remove usage of flags wherever
not required. (Lucas De Marchi)

v5: Address review comments. Move register defines. Modify mocs
info struct to avoid holes. (Luca De Marchi)

a0862cf2fe drm/xe: Refactor default device atomic settings 
The default behavior of device atomics depends on the
VM type and buffer allocation types. Device atomics are
expected to function with all types of allocations for
traditional applications/APIs. Additionally, in compute/SVM
API scenarios with fault mode or LR mode VMs, device atomics
must work with single-region allocations. In all other cases
device atomics should be disabled by default also on platforms
where we know device atomics doesn't on work on particular
allocations types.

v3: fault mode requires LR mode so only check for LR mode
    to determine compute API(Jose).
    Handle SMEM+LMEM BO's migration to LMEM where device
    atomics is expected to work. (Brian).
v2: Fix platform checks to correct atomics behaviour on PVC.

a6cd27d92a drm/panel-edp: Add ID for KD KD116N09-30NH-A016 
As evidenced by in-field reports, this panel shipped on pompom but we
never added the ID and thus we're stuck w/ conservative timings. The
panel was part of early patches but somehow got left off in the
end. :( Add it in now.

For future reference, EDID from this panel is:
	00ffffffffffff002c82121200000000
	321e0104951a0e780ae511965e55932c
	19505400000001010101010101010101

	004b443131364e3039333041313600f6

We use the ASCII string from decoding the EDID ("KD116N0930A16") as
the panel name.

46d4efcccc drm/msm/a6xx: Avoid a nullptr dereference when speedbin setting fails 
Calling a6xx_destroy() before adreno_gpu_init() leads to a null pointer
dereference on:

msm_gpu_cleanup() : platform_set_drvdata(gpu->pdev, NULL);

as gpu->pdev is only assigned in:

a6xx_gpu_init()
|_ adreno_gpu_init

Instead of relying on handwavy null checks down the cleanup chain,
explicitly de-allocate the LLC data and free a6xx_gpu instead.

c01c6066e6 drm/xe/device: implement transient flush 
Display surfaces can be tagged as transient by mapping it using one of
the various L3:XD PAT index modes on Xe2. The expectation is that KMD
needs to request transient data flush at the start of flip sequence to
ensure all transient data in L3 cache is flushed to memory. Add a
routine for this which we can then call from the display code.

v2: rebase(RK)
