This set of changes adds nvmem cell lookup entries for Tegra194 that are
used to read calibration data from the SoC fuses, and updates the reset
sources for Tegra234.
Other than that, included is a minor build fix for a missing dependency
that can be encountered very rarely in random config builds. Lastly some
kerneldoc comments are added to avoid build warnings.

The main theme for most of the changes this time is around the addition
of the support for SCMI v3.1 specification changes. Though one of the main
addition in the specification is the powercap protocol, that is still
work in progress and this set includes all other changes bit and pieces
scattered all around the different parts of the specification. There are
few bugs discovered during the process and associated fixes and some
refactoring to simplify the addition of v3.1 support. It mainly includes
the support for extended names, few newly added notifications and async
command support.
Apart from v3.1 SCMI changes, OPTEE transport gets support for dynamic
shared memory.

Couple of fixes to handle fragmented memory descriptors and incorrect
UUID parameter passed to ffa_partition_probe. Another fix deals with
the incorrect use of ffa_device's driver_data by the core driver.
Apart from these fixes, there is an addition of ffa_dev_get_drvdata helper
function and its use in optee driver.

Merge tag 'memory-controller-drv-5.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl into arm/drivers
Memory controller drivers for v5.19, part two
1. Cleanup: simplify platform_get_resource() calls by using
devm_platform_get_and_ioremap_resource() helper.
2. OMAP: allow building omap-gpmc as module and make it visible (it is
not selected by platform anymore).

Apple SoCs such as the M1 come with an embedded NVMe controller that
is not attached to any PCIe bus. Additionally, it doesn't conform
to the NVMe specification and requires a bunch of changes to command
submission and IOMMU configuration to work.

Apple SoCs such as the M1 come with an embedded NVMe coprocessor called

The NVMe co-processor on the Apple M1 uses a DMA address filter called
SART for some DMA transactions. This adds a simple driver used to
configure the memory regions from which DMA transactions are allowed.
Unlike a real IOMMU, SART does not support any pagetables and can't be
implemented inside the IOMMU subsystem using iommu_ops.
It also can't be implemented using dma_map_ops since not all DMA
transactions of the NVMe controller are filtered by SART.
Instead, most buffers have to be registered using the integrated NVMe
IOMMU and we can't have two separate dma_map_ops implementations for a
single device.

Apple SoCs such as the M1 come with a simple DMA address filter called
SART. Unlike a real IOMMU no pagetables can be configured but instead
DMA transactions can be allowed for up to 16 paddr regions. The consumer
also needs special support since not all DMA allocations have to be
added to this filter.

Apple SoCs such as the M1 come with multiple embedded co-processors
running proprietary firmware. Communication with those is established
over a simple mailbox using the RTKit IPC protocol.
This cannot be implemented inside the mailbox subsystem since on top
of communication over channels we also need support for starting,
hibernating and resetting these co-processors. We also need to
handle shared memory allocations differently depending on the
co-processor and don't want to split that across multiple drivers.

We want to allow the code inside drivers/soc/apple to be compiled with
COMPILE_TEST but this will currently result in linking errors because
ARCH_APPLE is not set and make will never recurse into
drivers/soc/apple.
Let's just unconditionally recurse into apple/ since all drivers
in there are guarded by config options anyways.

Due to lack of an helper like ffa_dev_get_drvdata, this driver was
fetching driver_data directly accessing the structure member. Now that
we have added an helper, just use the same instead.

Add a helper function to fetch ffa_dev's driver_data using
dev_get_drvdata. At the same time move existing ffa_dev_set_drvdata
to use dev_set_drvdata.

The ffa core driver currently assigns its own driver information
to individual ffa device driver_data which is wrong. Firstly, it leaks
this core driver information to individual ffa_device and hence to
ffa_driver. Secondly the ffa_device driver_data is for use by individual
ffa_driver and not for this core driver managing all those devices.

While we pass uuid_null intentionally to ffa_partition_probe in
ffa_setup_partitions to get the count of the partitions, it must not be
uuid_null in ffa_partition_info_get which is used by the ffa_drivers
to fetch the specific partition info passing the UUID of the partition.
Fix ffa_partition_info_get by passing the received uuid down to
ffa_partition_probe so that the correct partition information is fetched.
