Pull SoC driver updates from Arnd Bergmann:
"There are a few added drivers, but mostly the normal maintenance to
drivers for firmware, memory controller and other soc specific
hardware:
- The NXP QuickEngine gets modern MSI support, which allows some
cleanups to the GICv3 irqchip chip driver
- A new SoC specific driver for the Renesas R-Car MFIS unit is added,
encapsulating support for the on-chip mailbox and hwspinlock
implementations that are not easily separated into individual
drivers
- The Qualcomm SoC drivers add support for additional SoC
implementations, and flexibility around power management for the
serial-engine driver as well as probing the LLCC driver using
custom hardware descriptions inside of the device itself.
- Added support for the Samsung thermal management unit
- A cleanup to the Tegra 'PMC' driver interfaces to remove legacy
APIs and allow multiple PMC instances everywhere.
- Updates to the TI SCI and KNAS drivers to improve suspend/resume
support.
- Minor driver changes for mediatek, xilinx, allwinner, aspeed,
tegra, broadcom, amd, microchip and starfive specific drivers
- Memory controller updates for Tegra and Renesas for additional SoC
types and other improvements.
- Firmware driver updates for Arm FF-A, SMCCC and SCMI interfaces, to
update driver probing, object lifetimes and address minor bugs"

The GENI Serial Engine (SE) drivers (I2C, SPI, and SERIAL) currently
manage performance levels and operating points directly. This resulting
in code duplication across drivers. such as configuring a specific level
or find and apply an OPP based on a clock frequency.
Introduce two new helper APIs, geni_se_set_perf_level() and
geni_se_set_perf_opp(), addresses this issue by providing a streamlined
method for the GENI Serial Engine (SE) drivers to find and set the OPP
based on the desired performance level, thereby eliminating redundancy.

In an internal review from Airoha, it was notice that the RX DMA descriptor
bits and mask are wrong. These values probably refer to an old NPU firmware
never published. The previous value works correctly but it was reported
that in some specific condition in mixed scenario with both Ethernet and
WiFi offload it's possible that RX DMA descriptor signal wrong value with
the problem to the RX ring or packets getting dropped.
To handle these specific scenario, apply the new suggested bits mask from
Airoha.
Correct functionality of both AN7581 NPU and MT7996 variant were verified

Currently the database stores macrotile_mode in the data. However it
can be derived from the rest of the data: it should be used for UBWC
encoding >= 3.0 except for several corner cases (SM8150 and SC8180X).
The ubwc_bank_spread field seems to be based on the impreside data we
had for the MDSS and DPU programming. In some cases UBWC engine inside
the display controller doesn't need to program it, although bank spread
is to be enabled.
Bank swizzle is also currently stored as is, but it is almost standard
(banks 1-3 for UBWC 1.0 and 2-3 for other versions), the only exception
being Lemans (it uses only bank 3).
Add helpers returning values from the config for now. They will be
rewritten later, in a separate series, but having the helper now
simplifies refacroring the code later.

The QMI framework proposes a set of services which are defined by an
integer identifier. The different QMI client lookup for the services
via this identifier. Moreover, the function qmi_add_lookup() and
qmi_add_server() must match the service ID but the code in different
places set the same value but with a different macro name. These
macros are spreaded across the different subsystems implementing the
protocols associated with a service. It would make more sense to
define them in the QMI header for the sake of consistency and clarity.
This change use an unified naming for the services and enumerate the
ones implemented in the Linux kernel. More services can come later and
put the service ID in this same header.

Fix incorrect slice activation/deactivation accounting by replacing the
bitmap-based activation tracking with per-slice atomic reference counters.
This resolves mismatches that occur when multiple client drivers vote for
the same slice or when llcc_slice_getd() is called multiple times.
As part of this fix, simplify slice descriptor handling by eliminating
dynamic allocation. llcc_slice_getd() now returns a pointer to a
preallocated descriptor, removing the need for repeated allocation/free
cycles and ensuring consistent reference tracking across all users.

This patch extends the cmdq_pkt_write API to support SoCs that do not
have subsys ID mapping by introducing new register write APIs:
- cmdq_pkt_write_pa() and cmdq_pkt_write_subsys() replace
cmdq_pkt_write()
- cmdq_pkt_write_mask_pa() and cmdq_pkt_write_mask_subsys() replace
cmdq_pkt_write_mask()
To ensure consistent function pointer interfaces, both
cmdq_pkt_write_pa() and cmdq_pkt_write_subsys() provide subsys and
pa_base parameters. This unifies how register writes are invoked,
regardless of whether subsys ID is supported by the device.
All GCEs support writing registers by PA (with mask) without subsys,
but this requires extra GCE instructions to convert the PA into a GCE
readable format, reducing performance compared to using subsys directly.
Therefore, subsys is preferred for register writes when available.
API documentation and function pointer declarations in cmdq_client_reg
have been updated. The original write APIs will be removed after all
CMDQ users transition to the new interfaces.

When GCE executes instructions, it typically locates the corresponding
hardware register using the subsys ID. For hardware that does not
support subsys ID, the subsys ID is set to an invalid value, and the
physical address must be used to generate GCE instructions.
The main advantage of using subsys ID is to reduce the number of
instructions. Without subsys ID, an additional `ASSIGN` instruction
is needed to assign the high bytes of the physical address, which can
impact performance if too many instructions are required. However, if
the hardware does not support subsys ID, using the physical address
is the only option to achieve the same functionality.
This commit adds a pa_base parsing flow to the cmdq_client_reg structure
to handle hardware without subsys ID support.

Introduce a new PAS context-aware function, qcom_mdt_pas_load(), for
remote processor drivers. This function utilizes the PAS context
pointer returned from qcom_scm_pas_ctx_init() to perform firmware
metadata verification and memory setup via SMC calls.
The qcom_mdt_pas_load() and qcom_mdt_load() functions are largely
similar, but the former is designed for clients using the PAS
context-based data structure. Over time, all users of qcom_mdt_load()
can be migrated to use qcom_mdt_pas_load() for consistency and
improved abstraction.
As the remoteproc PAS driver (qcom_q6v5_pas) has already adopted the
PAS context-based approach, update it to use qcom_mdt_pas_load().

As a superset of the existing metadata context, the PAS context
structure enables both remoteproc and non-remoteproc subsystems to
better support scenarios where the SoC runs with or without the Gunyah
hypervisor. To reflect this, relevant SCM and metadata functions are
updated to incorporate PAS context awareness and remove metadata context
data structure completely.
