Pull ARM SoC driver updates from Arnd Bergmann:
"A couple of subsystems have their own subsystem maintainers but choose
to have the code merged through the soc tree as upstream, as the code
tends to be used across multiple SoCs or has SoC specific drivers
itself:
- memory controllers:
Krzysztof Kozlowski takes ownership of the drivers/memory subsystem
and its drivers, starting out with a set of cleanup patches.
A larger driver for the Tegra memory controller that was
accidentally missed for v5.8 is now added.
- reset controllers:
Only minor updates to drivers/reset this time
- firmware:
The "turris mox" firmware driver gains support for signed firmware
blobs The tegra firmware driver gets extended to export some debug
information Various updates to i.MX firmware drivers, mostly
cosmetic
- ARM SCMI/SCPI:
A new mechanism for platform notifications is added, among a number
of minor changes.
- optee:
Probing of the TEE bus is rewritten to better support detection of
devices that depend on the tee-supplicant user space. A new
firmware based trusted platform module (fTPM) driver is added based
on OP-TEE
- SoC attributes:
A new driver is added to provide a generic soc_device for
identifying a machine through the SMCCC ARCH_SOC_ID firmware
interface rather than by probing SoC family specific registers.
The series also contains some cleanups to the common soc_device
code.
There are also a number of updates to SoC specific drivers, the main
ones are:
- Mediatek cmdq driver gains a few in-kernel interfaces
- Minor updates to Qualcomm RPMh, socinfo, rpm drivers, mostly adding
support for additional SoC variants
- The Qualcomm GENI core code gains interconnect path voting and
performance level support, and integrating this into a number of
device drivers.
- A new driver for Samsung Exynos5800 voltage coupler for
- Renesas RZ/G2H (R8A774E1) SoC support gets added to a couple of SoC
specific device drivers
- Updates to the TI K3 Ring Accelerator driver"

Add driver for the Qualcomm interconnect buses found in MSM8916 based
platforms. The topology consists of three NoCs that are controlled by
a remote processor that collects the aggregated bandwidth for each
master-slave pairs.

There is a new helper function for removing all nodes. Let's use it instead
of duplicating the code.

The macro to generate a Bus Controller Manager (BCM) TCS command is used
by the interconnect driver but might also be interesting to other
drivers that need to construct TCS commands for sub processors so move
it out of the sdm845 specific file and into the header.

There is one compilation error when CONFIG_INTERCONNECT_QCOM_QCS404=y and
CONFIG_INTERCONNECT_QCOM_SMD_RPM=y, as well as CONFIG_COMPILE_TEST=y,
but CONFIG_QCOM_SMD_RPM is not set, logs as below:
drivers/interconnect/qcom/smd-rpm.o: In function `qcom_icc_rpm_smd_send':
smd-rpm.c:(.text+0xe4): undefined reference to `qcom_rpm_smd_write'
Makefile:1071: recipe for target 'vmlinux' failed
make: *** [vmlinux] Error 1
This is because
INTERCONNECT_QCOM_QCS404 depends on QCOM_SMD_RPM || COMPILE_TEST.
Here CONFIG_COMPILE_TEST=y, so CONFIG_INTERCONNECT_QCOM_SMD_RPM
is selected. If CONFIG_QCOM_SMD_RPM is not set, then
qcom_rpm_smd_write() is not defined, and compilation error happen.
Fix this by removing COMPILE_TEST from CONFIG_INTERCONNECT_QCOM_QCS404.

On some Qualcomm SoCs, there is a remote processor, which controls some of
the Network-On-Chip interconnect resources. Other CPUs express their needs
by communicating with this processor. Add a driver to handle communication
with this remote processor.

Consumers may have use cases with different bandwidth requirements based
on the system or driver state. The consumer driver can append a specific
tag to the path and pass this information to the interconnect platform
driver to do the aggregation based on this state.
Introduce icc_set_tag() function that will allow the consumers to append
an optional tag to each path. The aggregation of these tagged paths is
platform specific.
