Pull dma-mapping updates from Marek Szyprowski:
- added support for batched cache sync, what improves performance of
dma_map/unmap_sg() operations on ARM64 architecture (Barry Song)
- introduced DMA_ATTR_CC_SHARED attribute for explicitly shared memory
used in confidential computing (Jiri Pirko)
- refactored spaghetti-like code in drivers/of/of_reserved_mem.c and
its clients (Marek Szyprowski, shared branch with device-tree updates
to avoid merge conflicts)
- prepared Contiguous Memory Allocator related code for making dma-buf
drivers modularized (Maxime Ripard)
- added support for benchmarking dma_map_sg() calls to tools/dma
utility (Qinxin Xia)

Move init function from OF_DECLARE() argument to the given reserved
memory region ops structure and then pass that structure to the
OF_DECLARE() initializer. This node_init callback is mandatory for the
reserved mem driver. Such change makes it possible in the future to add
more functions called by the generic code before given memory region is
initialized and rmem object is created.

In Tegra264, different components from memory subsystems like Memory
Controller Fabric (MCF), HUB, HUB Common (HUBC), Side Band Shim (SBS)
and channels have different interrupt lines for receiving memory
controller error interrupts.
Add support for logging memory controller errors reported by these
memory subsystems on Tegra264 by:
- Renaming tegra_mc_error_names array to tegra20_mc_error_names
because it has a different bit index for error names compared to
Tegra264.
- Defining the intmask registers and mask values supported for
Tegra264.
- Registering interrupt handlers for interrupts associated with these
different MC components which read the interrupt status registers to
determine the type of violation that occurred.

Introduce new SoC specific fields in tegra_mc_soc struct for high
address mask and error status type mask because Tegra264 has different
values for these than the existing devices. Error status registers
e.g. MC_ERR_STATUS_0 has few bits which indicate the type of the
error. In order to obtain such type of error from error status
register, we use error status type mask. Similarly, these error status
registers have bits which indicate the higher address bits of the
address responsible for mc error. In order to obtain such higher
address, we use high address mask. Make this change to prepare for
adding MC interrupt support for Tegra264.

Add support to handle multiple MC interrupts lines, as supported by

handlers into tegra_mc_soc struct, so as to specify SoC specific

The DBB clock is needed by many IP blocks in order to access system
memory via the data backbone. The memory controller and external memory
controllers are the central place where these accesses are managed, so
make sure that the clock can be controlled from the corresponding
driver.
Note that not all drivers fully register bandwidth requests, and hence
the EMC driver doesn't have enough information to know when it's safe to
switch the clock off, so for now it will be kept on permanently.

This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

Add support to enable Memory Controller (MC) and External Memory
Controller (EMC) drivers for Tegra264. The nodes for MC and EMC are
mostly the same as Tegra234 but differ in number of channels and
interrupt numbers.
The patch also adds the bandwidth manager definitions required for
Tegra264 and uses them to populate the memory client table. All of
these are needed to properly enable memory interconnect (ICC) support.

Now that a "brcm,brcmstb-memc-ddr-rev-b.2.x" fallback compatible string
has been defined, we can greatly simplify the matching within the driver
to only look for that compatible string and nothing else.
The fallback "brcm,brcmstb-memc-ddr" is also updated to assume the V21
register layout since that is the most common nowadays.

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().

Add initial ostd setting for mt8186. All the settings come from DE.
These settings help adjust Multimedia HW's bandwidth limits to achieve
a balanced bandwidth requirement. Without this, the VENC HW works
abnormal while stress testing.

Use syscon_regmap_lookup_by_phandle_args() which is a wrapper over
syscon_regmap_lookup_by_phandle() combined with getting the syscon
argument. Except simpler code this annotates within one line that given
phandle has arguments, so grepping for code would be easier.
