This patchset is to support i.MX8MP NoC settings, i.MX8MP NoC initial
value after power up is invalid, need set a valid value after related
power domain up.
This patchset also includes two patch[1,2] during my development to enable
the ICC feature for i.MX8MP.
I not include ddrc DVFS in this patchset, ths patchset is only to
support NoC value mode/priority/ext_control being set to a valid value
that suggested by i.MX Chip Design Team. The value is same as NXP
downstream one inside Arm Trusted Firmware:

Iterating over the links for an entity is a somewhat common need
through the media subsystem, but generally the assumption is that
they will all be data links. To meet that assumption add a new macro
that iterates through an entity's links and skips non-data links.

Add a helper macro for the situations where a non-MC driver needs to
call a state-operation (operation which takes a subdev state as a
parameter) in try-context in another subdev.
The macro allocates a new subdev state for the called subdev and frees
the state afterwards.
An example use case is a media platform driver testing if a
v4l2_subdev_format would be accepted by a source subdev.
This should not be used in MC drivers.

ASoC: Updates for v5.20
This is a big release thus far and there will probably be more changes
to come, it's a combination of a larger than usual crop of new drivers
and some subsysetm wide cleanups from Charles rather than anything
structural. The SOF and Intel DSP code both also continue to be very
actively developed.
- Restructing of the set_fmt() callbacks to be specified in terms of
the device rather than with semantics depending on if the device is
supposed to be a CODEC or SoC, making things clearer in situations
like CODEC to CODEC links.
- Clean up of the way we flag which DAI naming scheme we use to reflect
the progress that's been made modernising things.
- Merge of more of the Intel AVS driver stack, including some board
integrations.
- New version 4 mechanism for communication with SOF DSPs.
- Suppoort for dynamically selecting the PLL to use at runtime on i.MX
platforms.
- Improvements for CODEC to CODEC support in the generic cards.
- Support for AMD Jadeite and various machines, Intel MetorLake DSPs,
Mediatek MT8186 DSPs and MT6366, nVidia Tegra MDDRC, OPE and PEQ, NXP
TFA9890, Qualcomm SDM845, WCD9335 and WAS883x, and Texas Instruments
TAS2780.
The helper functions that test validity of colorspace-related fields
use the last value of the corresponding enums. This isn't very
future-proof, as there's a high chance someone adding a new value may
forget to update the helpers. Add new "LAST" entries to the enumerations
to improve this, and keep them private to the kernel.

To avoid circular dependencies, cpumask keeps simple (almost) one-line
wrappers around find_bit() in a c-file.
Commit 47d8c15615 ("include: move find.h from asm_generic to linux")
moved find.h header out of asm_generic include path, and it helped to fix
many circular dependencies, including some in cpumask.h.
This patch moves those one-liners to header files.

When an MLO AP is transmitting to a non-MLO station, addr2 should be set
to a link address. This should be done before the frame is encrypted as
otherwise aad verification would fail. In case of software encryption
this can't be left for the device to handle, and should be done by
mac80211 when building the frame hdr.

We might assign -1 to it in some cases when key is NULL,

To support SNP, IOMMU needs to be enabled, and prohibits IOMMU
configurations where DTE[Mode]=0, which means it cannot be supported with
IOMMU passthrough domain (a.k.a IOMMU_DOMAIN_IDENTITY),
and when AMD IOMMU driver is configured to not use the IOMMU host (v1) page
table. Otherwise, RMP table initialization could cause the system to crash.
The request to enable SNP support in IOMMU must be done before PCI
initialization state of the IOMMU driver because enabling SNP affects
how IOMMU driver sets up IOMMU data structures (i.e. DTE).
Unlike other IOMMU features, SNP feature does not have an enable bit in
the IOMMU control register. Instead, the IOMMU driver introduces
an amd_iommu_snp_en variable to track enabling state of SNP.
Introduce amd_iommu_snp_enable() for other drivers to request enabling
the SNP support in IOMMU, which checks all prerequisites and determines
if the feature can be safely enabled.
Please see the IOMMU spec section 2.12 for further details.

ARIA(RFC 5794) is a symmetric block cipher algorithm.
This algorithm is being used widely in South Korea as a standard cipher
algorithm.
This code is written based on the ARIA implementation of OpenSSL.
The OpenSSL code is based on the distributed source code[1] by KISA.
ARIA has three key sizes and corresponding rounds.
ARIA128: 12 rounds.
ARIA192: 14 rounds.
ARIA245: 16 rounds.
