The FUSE driver isn't a critical driver and currently it only provides

thus, it's fine if FUSE driver fails to load.
Let's remove the erroneous Kconfig dependency and let the FUSE driver to

firmware: arm_ffa: Split up ffa_ops into info, message and memory operations
In preparation to make memory operations accessible for a non
ffa_driver/device, it is better to split the ffa_ops into different
categories of operations: info, message and memory. The info and memory
are ffa_device independent and can be used without any associated
ffa_device from a non ffa_driver.
However, we don't export these info and memory APIs yet without the user.
The first users of these APIs can export them.
firmware: arm_ffa: Set up 32bit execution mode flag using partiion property
FF-A v1.1 adds a flag in the partition properties to indicate if the
partition runs in the AArch32 or AArch64 execution state. Use the same
to set-up the 32-bit execution flag mode in the ffa_dev automatically
if the detected firmware version is above v1.0 and ignore any requests
to do the same from the ffa_driver.
firmware: arm_ffa: Add v1.1 get_partition_info support
FF-A v1.1 adds support to discovery the UUIDs of the partitions that was
missing in v1.0 and which the driver workarounds by using UUIDs supplied
by the ffa_drivers.
Add the v1.1 get_partition_info support and disable the workaround if
the detected FF-A version is greater than v1.0.
firmware: arm_ffa: Make memory apis ffa_device independent
There is a requirement to make memory APIs independent of the ffa_device.
One of the use-case is to have a common memory driver that manages the
memory for all the ffa_devices. That common memory driver won't be a
ffa_driver or won't have any ffa_device associated with it. So having
these memory APIs accessible without a ffa_device is needed and should
be possible as most of these are handled by the partition manager(SPM
or hypervisor).
Drop the ffa_device argument to the memory APIs and make them ffa_device
independent.
firmware: arm_ffa: Use FFA_FEATURES to detect if native versions are supported
Currently, the ffa_dev->mode_32bit is use to detect if the native 64-bit
or 32-bit versions of FF-A ABI needs to be used. However for the FF-A
memory ABIs, it is not dependent on the ffa_device(i.e. the partition)
itself, but the partition manager(SPM).
So, the FFA_FEATURES can be use to detect if the native 64bit ABIs are
supported or not and appropriate calls can be made based on that.
Use FFA_FEATURES to detect if native versions of MEM_LEND or MEM_SHARE
are implemented and make of the same to use native memory ABIs later on.
firmware: arm_ffa: Add support for querying FF-A features
Add support for FFA_FEATURES to discover properties supported at the
FF-A interface. This interface can be used to query:
- If an FF-A interface is implemented by the component at the higher EL,
- If an implemented FF-A interface also implements any optional features
described in its interface definition, and
- Any implementation details exported by an implemented FF-A interface
as described in its interface definition.
firmware: arm_ffa: Add pointer to the ffa_dev_ops in struct ffa_dev
Currently ffa_dev_ops_get() is the way to fetch the ffa_dev_ops pointer.
It checks if the ffa_dev structure pointer is valid before returning the
ffa_dev_ops pointer.
Instead, the pointer can be made part of the ffa_dev structure and since
the core driver is incharge of creating ffa_device for each identified
partition, there is no need to check for the validity explicitly if the
pointer is embedded in the structure.
Add the pointer to the ffa_dev_ops in the ffa_dev structure itself and
initialise the same as part of creation of the device.

memory: mtk-smi: Add enable IOMMU SMC command for MM master
For concerns about security, the register to enable/disable IOMMU of
SMI LARB should only be configured in secure world. Thus, we add some
SMC command for multimedia master to enable/disable MM IOMMU in ATF by
setting the register of SMI LARB. This function is prepared for MT8188.

memory: mtk-smi: Add return value for configure port function
In MT8188, the register to enable/disable IOMMU can only be configured
in secure world by SMC call. We should add a return value for configure
port function for preparation because SMC call may return an error result.
In mt8188, there are two smi-common HW, one is for vdo(video output),
the other is for vpp(video processing pipe). They connect with different
smi-larbs, then some setting(bus_sel) is different. Differentiate them
with the compatible string.

soc: mediatek: mtk-svs: Explicitly include bitfield header
Commit a92438c5a30a ("soc: mediatek: mtk-svs: Use bitfield access macros
where possible") introduced the use of FIELD_GET and FIELD_PREP macros,
which are defined in the bitfield header. Add an explicit include for it
so we're sure to have the symbols defined independently of the config.

mm/mprotect: only reference swap pfn page if type match
Yu Zhao reported a bug after the commit "mm/swap: Add swp_offset_pfn() to
fetch PFN from swap entry" added a check in swp_offset_pfn() for swap type [1]:
When user tries to create a DAMON context via the DAMON debugfs interface
with a name of an already existing context, the context directory creation
fails but a new context is created and added in the internal data
structure, due to absence of the directory creation success check. As a
result, memory could leak and DAMON cannot be turned on. An example test
case is as below:
Return value of 'debugfs_create_dir()' is expected to be ignored in
general, but this is an exceptional case as DAMON feature is depending
on the debugfs functionality and it has the potential duplicate name
issue. This commit therefore fixes the issue by checking the directory
creation failure and immediately return the error in the case.
