irq_domain_create_simple() takes fwnode as the first argument. It can be
extracted from the struct device using dev_fwnode() helper instead of
using of_node with of_fwnode_handle().

So use the dev_fwnode() helper.

62b7d68352 drm/msm/dpu: Filter modes based on adjusted mode clock
Filter out modes that have a clock rate greater than the max core clock
rate when adjusted for the perf clock factor

This is especially important for chipsets such as QCS615 that have lower
limits for the MDP max core clock.

Since the core CRTC clock is at least the mode clock (adjusted for the
perf clock factor) [1], the modes supported by the driver should be less
than the max core clock rate.

ASoC: Intel: avs: Refactor machine-board registration
Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:

Set of patches all connected to the machine-board registration process
and the board_selection.c file. Apart from LOC reduction, allows for
multiple cards of the same 'type' e.g.: avs_rt5640, to be present
simultanetously without any workarounds or tricks. The last patch
improves debugability - helps us (the devs) deal with basic I2S-boards
issues out there without forcing the user to constantly switch between
debug-friendly and non-debug options.

--

Initially I wanted to have the first two patches (new implementation and
the follow up cleanup) to be just one patch. However, the git diff, even
with --patience does not look good, at least in my opinion. Decided to
split the changes into two separate patches to make it easy to review
and comment.

As the first two patches carry heaviest load, the summary:
- provide a unified avs_register_board() wrapper for
  platform_device_register_data(PLATFORM_DEVID_AUTO). The _AUTO is what
  makes every device name unique and prevents any naming conflicts to
  occur when matching components <-> cards in runtime

- provide avs_register_board_pdata(), a wrapper one-level above
  avs_register_board() that takes all custom parameters in its argument
  list so that the initialization of 'struct avs_mach_pdata' does not
  need to be repeated in every function like its done today

- make use of the two above to write simpler registration functions:
  1. init any interface-type-specific values e.g.: SSP port for I2S
     board
  2. call avs_register_board_pdata()
  3. register the ASoC component with avs_register_xxx_component()

In regard to the last three patches - two are simplifications, no
functional changes just LOC reduction and readability.
The last one is to improve debug-ability, especially when working in the
open field - often we, the devs, find it useful when debugging
production systems to run i2s_test (the debug board) without impacting
the 'real' board e.g.: avs_rt5640. By default i2s_test is empty so a
typical user and their scenarios are not impacted.

ASoC: use int type to store negative error codes
Merge series from Qianfeng Rong <rongqianfeng@vivo.com>:

The 'ret' variable usually is used to store returns from some functions,
which return either zero on success or negative error codes on failure.

Storing the negative error codes in unsigned type, doesn't cause an issue
at runtime but it's ugly as pants.  Additionally, assigning negative error
codes to unsigned type may trigger a GCC warning when the -Wsign-conversion
flag is enabled.

Change "ret" from u32/unsigned int to int type.  No effect on runtime.

ee372e6451 KVM: arm64: nv: Fix ATS12 handling of single-stage translation
Volodymyr reports that using a Xen DomU as a nested guest (where
HCR_EL2.E2H == 0), ATS12 results in a translation that stops at
the L2's S1, which isn't something you'd normally expects.

Comparing the code against the spec proves to be illuminating,
and suggests that the author of such code must have been tired,
cross-eyed, drunk, or maybe all of the above.

The gist of it is that, apart from HCR_EL2.VM or HCR_EL2.DC being
0, only the use of the EL2&0 translation regime limits the walk
to S1 only, and that we must finish the S2 walk in any other case.
Which solves the above issue, as E2H==0 indicates that ATS12 walks
the EL1&0 translation regime.

Explicitly checking for EL2&0 fixes this.

Fix the rules in tools/testing/selftests/vfio/.gitignore to not ignore

This change should be a no-op, since these files are already tracked by git
and thus git will not ignore updates to them even though they match the
ignore rules in the VFIO selftests .gitignore file.

However, they do generate warnings with W=1, as reported by the kernel test

ec0ab059d4 KVM: arm64: Fix vcpu_{read,write}_sys_reg() accessors
Volodymyr reports (again!) that under some circumstances (E2H==0,
walking S1 PTs), PAR_EL1 doesn't report the value of the latest
walk in the CPU register, but that instead the value is written to
the backing store.

Further investigation indicates that the root cause of this is
that a group of registers (PAR_EL1, TPIDR*_EL{0,1}, the *32_EL2 dregs)
should always be considered as "on CPU", as they are not remapped
between EL1 and EL2.

We fail to treat them accordingly, and end-up considering that
the register (PAR_EL1 in this example) should be written to memory
instead of in the register.

While it would be possible to quickly work around it, it is obvious
that the way we track these things at the moment is pretty horrible,
and could do with some improvement.

Revamp the whole thing by:

- defining a location for a register (memory, cpu), potentially
  depending on the state of the vcpu

- define a transformation for this register (mapped register, potential
  translation, special register needing some particular attention)

- convey this information in a structure that can be easily passed
  around

As a result, the accessors themselves become much simpler, as the
state is explicit instead of being driven by hard-to-understand
conventions.

We get rid of the "pure EL2 register" notion, which wasn't very
useful, and add sanitisation of the values by applying the RESx
masks as required, something that was missing so far.

And of course, we add the missing registers to the list, with the
indication that they are always loaded.

112f7d3cff ALSA: hda: Avoid binding with SOF for SKL/KBL platforms
For Intel SKL and KBL platforms, it may be bound with one of three
HD-audio drivers (AVS, SOF and legacy).  AVS is the preferred one when
DMIC is detected, and that's how it's defined in the snd-intel-dspcfg
config table.

But, when AVS driver is disabled (CONFIG_SND_SOC_INTEL_AVS=n), the
device may be bound freely with either SOF or legacy driver.
Before 6.17, the legacy driver took it primarily, but on 6.17, likely
due to the recent code shuffling, SOF driver seems taking it at first,
and fails to probe.  For avoiding the regression, we should enforce to
bind those with the legacy HD-audio drvier when AVS is disabled.

This patch adds the extra two entries in intel-dspcfg table that are
applied only when CONFIG_SND_SOC_INTEL_AVS=n, for binding with the
legacy driver.

Note that there are entries for APL in that config table block, but
APL may be supported by SOF for certain setups, so the choice can't be
exclusive.  Hence this patch includes only SKL and KBL.

30c2b98aa8 x86/apic: Add new driver for Secure AVIC
The Secure AVIC feature provides SEV-SNP guests hardware acceleration for
performance sensitive APIC accesses while securely managing the guest-owned
APIC state through the use of a private APIC backing page. 

This helps prevent the hypervisor from generating unexpected interrupts for
a vCPU or otherwise violate architectural assumptions around the APIC
behavior.

Add a new x2APIC driver that will serve as the base of the Secure AVIC
support. It is initially the same as the x2APIC physical driver (without IPI
callbacks), but will be modified as features are implemented.

As the new driver does not implement Secure AVIC features yet, if the
hypervisor sets the Secure AVIC bit in SEV_STATUS, maintain the existing
behavior to enforce the guest termination.

57a48a2619 dt-bindings: PCI: ti,am65: Extend for use with PVU
The Peripheral Virtualization Unit (PVU) on the AM65 SoC is capable of
restricting DMA from PCIe devices to specific regions of host memory.
Add the optional property "memory-regions" to point to such regions of
memory when PVU is used.

Since the PVU deals with system physical addresses, utilizing the PVU
with PCIe devices also requires setting up the VMAP registers to map the
Requester ID of the PCIe device to the CBA Virtual ID, which in turn is
mapped to the system physical address. Hence, describe the VMAP
registers which are optional unless the PVU shall be used for PCIe.
