Qualcomm driver updates for v5.20
This introduces a new driver that requests interconnect bandwidth based
on throughput measurements of the bwmon hardware blocks found associated
with, among other things, the CPU subsystem on many Qualcomm platforms.
It introduces support for the SCM wrapper driver to vote for
interconnect bandwidth for operations that needs bandwidth to the crypto
engine. This ensures both performance and guards against issues caused
by lacking votes for this path.
The socinfo driver gains knowledge about the SC7180P SoC.
It contains a range of fixes for spelling mistakes, refcount leaks in
various drivers and removes some redundant code from the apr remove
path.
The SCM DT bindings are updated to declare support for QCS404, SM6125
and SDX65.
The command db driver has a strncpy() converted to strscpy_pad() and
then back again with proper documentation to why this was the right API.

When building this driver for an architecture that does not support
CONFIG_PM_SLEEP, such as hexagon, the following warnings occur:
drivers/soc/mediatek/mtk-svs.c:1481:12: error: unused function 'svs_suspend' [-Werror,-Wunused-function]
static int svs_suspend(struct device *dev)
^
drivers/soc/mediatek/mtk-svs.c:1515:12: error: unused function 'svs_resume' [-Werror,-Wunused-function]
static int svs_resume(struct device *dev)
^
2 errors generated.
This happens because SIMPLE_DEV_PM_OPS uses SET_SYSTEM_SLEEP_PM_OPS,
which evaluates to nothing when CONFIG_PM_SLEEP is not set, leaving the
functions unused in the eyes of the compiler.
This problem was rectified in commit 1a3c7bb088 ("PM: core: Add new
*_PM_OPS macros, deprecate old ones") with new macros. Use
DEFINE_SIMPLE_DEV_PM_OPS to fix the warning while not changing
svs_pm_ops when CONFIG_PM_SLEEP is set.

MediaTek SoCs have multiple MFG power-domains, exclusively used for
the GPU which, in turn, requires external power supplies: make sure
to have the MTK_SCPD_DOMAIN_SUPPLY cap on the two topmost MFGs to
allow voting for regulators on/off upon usage of these power domains.
This also ensures that the SRAM is actually powered and that we're
not relying on the bootloader leaving this supply on when performing
the first (and latter) poweron sequence for these domains' sram.

Bandwidth monitoring (BWMON) sits between various subsytems like CPU,
GPU, Last Level caches and memory subsystem. The BWMON can be
configured to monitor the data throuhput between memory and other
subsytems. The throughput is measured within specified sampling window
and is used to vote for corresponding interconnect bandwidth.
Current implementation brings support for BWMON v4, used for example on
SDM845 to measure bandwidth between CPU (gladiator_noc) and Last Level
Cache (memnoc). Usage of this BWMON allows to remove fixed bandwidth
votes from cpufreq (CPU nodes) thus achieve high memory throughput even
with lower CPU frequencies.
The driver was tested on SDM845.

In case of error, of_iomap() returns NULL pointer not ERR_PTR().
The IS_ERR() test in the return value check should be replaced
with NULL test and return -ENOMEM as error value.

When compiling with -Wformat, clang emits the following warnings:

The types of these arguments are unconditionally defined, so this patch
updates the format character to the correct one and change type of
remote_host to "u16" to match with other types.

The kernel test robot found this inconsistency:
drivers/soc/ixp4xx/ixp4xx-npe.c:737:34: warning:
'ixp4xx_npe_of_match' defined but not used [-Wunused-const-variable=]
737 | static const struct of_device_id ixp4xx_npe_of_match[] = {
This is because the match is enclosed in the of_match_ptr()
which compiles into NULL when OF is disabled and this
is unnecessary.
Fix it by dropping of_match_ptr() around the match.

Every iteration of for_each_available_child_of_node() decrements
the reference count of the previous node.
When breaking early from a for_each_available_child_of_node() loop,
we need to explicitly call of_node_put() on the child node.
Add missing of_node_put() to avoid refcount leak.

SGI interrupt register and reset is performed by EEMI ioctl
IOCTL_REGISTER_SGI. However, this is not correct use of EEMI call.
SGI registration functionality does not qualify as energy management
activity and so shouldn't be mapped to EEMI call.
This new call will replace IOCTL_REGISTER_SGI and will be handled by TF-A
specific handler in TF-A. To maintain backward compatibility for a while
firmware driver will still use IOCTL_REGISTER_SGI as fallback strategy if
new call fails or is not supported by TF-A.
This new design also helps to make TF-A as pass through layer for EEMI
calls. So we don't have to maintain PM_IOCTL as EEMI API ID in TF-A.

Commit ac0126a017 ("soc: qcom: cmd-db: replace strncpy() with
strscpy_pad()") breaks booting on my sc7280-herobrine-herobrine
device. From printouts I see that at bootup the function is called
with an id of "lnbclka2" which is 8 bytes big.
Previously all 8 bytes of this string were copied to the
destination. Now only 7 bytes will be copied since strscpy_pad() saves
a byte for '\0' termination.
We don't need the '\0' termination in the destination. Let's go back
to strncpy(). According to the warning:
If a caller is using non-NUL-terminated strings, strncpy() can still
be used, but destinations should be marked with the __nonstring
attribute to avoid future compiler warnings.
...so we'll do that.
While we're at it, let's change the query array to use
"sizeof(ent->id)" so it can't possibly go out of sync with our later
copy.
