Since commit d492cc2573a0 ("driver core: device.h: make struct bus_type
a const *"), the driver core can properly handle constant struct
bus_type, move the s3c6410_subsys variable to be a constant structure as
well, placing it into read-only memory which can not be modified at
runtime.

Pull ARM SoC driver updates from Arnd Bergmann:
"This is the usual mix of updates for drivers that are used on (mostly
ARM) SoCs with no other top-level subsystem tree, including:
- The SCMI firmware subsystem gains support for version 3.2 of the
specification and updates to the notification code
- Feature updates for Tegra and Qualcomm platforms for added hardware
support
- A number of platforms get soc_device additions for identifying
newly added chips from Renesas, Qualcomm, Mediatek and Google
- Trivial improvements for firmware and memory drivers amongst
others, in particular 'const' annotations throughout multiple
subsystems"

A few Qualcomm driver fixes for v6.9
This fixes a "defined but not used"-warning in SPM driver when kernel is
built without regulator support, and corrects a couple of kernel-doc
issues in aoss and geni-se drivers.

struct bus_type, move the tee_bus_type variable to be a constant

the Resource Isolation Framework (RIF). From RIF point of view,
the FMC2 is composed of several independent resources, listed below,
which can be assigned to different security and compartment domains:
- 0: Common FMC_CFGR register.
- 1: EBI controller for Chip Select 1.
- 2: EBI controller for Chip Select 2.
- 3: EBI controller for Chip Select 3.

- CFGR register has been added,
- the bit used to enable the IP has moved from BCR1 to CFGR,
- the timeout for CEx deassertion has moved from PCSCNTR to BCRx,
- the continuous clock enable has moved from BCR1 to CFGR,
- the clk divide ratio has moved from BCR1 to CFGR.
The MP1 SoCs have only one signal to manage all the controllers (NWAIT).
The MP25 SOC has one RNB signal for the NAND controller and one NWAIT
signal for the memory controller.
Let's use a platform data structure for parameters that will differ
between MP1 and MP25.

Add a new compatible string to support MP25 SoC.
On MP1 SoC, RNB signal (NAND controller signal) and NWAIT signal (PSRAM
controller signal) have been integrated together in the SoC. That means
that the NAND controller and the PSRAM controller (if the signal is
used) can not be used at the same time. On MP25 SoC, the 2 signals can
be used outside the SoC, so there is no more restrictions.
MP1 SoC also embeds revision 1.1 of the FMC2 IP when MP25 SoC embeds
revision 2.0 of the FMC2 IP.
MP25 SoC is also using PSCI OS-initiated mode, so allow a single
'power-domains' entry for STM32 FMC2. As MP1 will move on PSCI
OS-initiated mode, add this property as optional for all FMC2 variants.

Some of the names for the Tegra234 DLA clients are not unique and do not
align with the name of the client ID definitions. Therefore, it is not
possible to determine the exact DLA client from messages that print the
client name. Fix this by correcting the DLA memory client names for
Tegra234 to align with the name of the corresponding memory client ID.
Note that although the client names are also used by the interconnect
framework, interconnect support for the DLA clients has not been added
and so this issue does not impact the interconnect support.

Samsung SoC driver changes for v6.9, part two
1. Extend Exynos PMU (Power Management Unit) driver being also the
syscon to main system controller registers block, to support Google
GS101. The Google GS101 has PMU registers protected and writing is
available only via SMC. The Exynos PMU will register its own custom
regmap for such case of mixed MMIO+SMC.
2. Rework Samsung watchdog driver to get the regmap to PMU block not
via syscon API, but from the Exynos PMU driver. This is necessary
for the watchdog driver to work on Google GS101.

than syscon_regmap_lookup_by_phandle(). As this driver no longer depends
on mfd syscon remove that header and Kconfig dependency.

Some Exynos based SoCs like Tensor gs101 protect the PMU registers for
security hardening reasons so that they are only write accessible in el3
via an SMC call.
As most Exynos drivers that need to write PMU registers currently obtain a
regmap via syscon (phys, pinctrl, watchdog). Support for the above usecase
is implemented in this driver using a custom regmap similar to syscon to
handle the SMC call. Platforms that don't secure PMU registers, get a mmio
regmap like before. As regmaps abstract out the underlying register access
changes to the leaf drivers are minimal.
A new API exynos_get_pmu_regmap_by_phandle() is provided for leaf drivers
that currently use syscon_regmap_lookup_by_phandle(). This also handles
deferred probing.

Qualcomm driver updates for v6.9
This introduces the Qualcomm Programmable Boot Sequencer (PBS) driver.
The Qualcomm SMEM no longer acquires the hwspinlock during the "get"
operation, to improve the system behavior during the recovery of a
remoteproc that crashed with the hwspinlock held.
The Qualcomm Always On Subsystem (AOSS) message protocol driver gains
tracepoints, printf annotation, and a debugfs interface is introduced
for tweaking system properties during development and debugging.
The Qualcomm socinfo driver gains data for SM8475, QCM8550 and
QCS8550 platforms, and the PM2250 is renamed to PM4125.
Support for controlling the voltage regulator in SPM/SAW2 is introduced.
The gfx.lvl power-domain is dropped for SA8540P, as this resource was
incorrectly inherited from SC8280XP.
Additionally some code cleanup improvements is introduced across APR,
LLCC, SMP2P and SPM.

The SPM / SAW2 device also provides a voltage regulator functionality
with optional AVS (Adaptive Voltage Scaling) support. The exact register
sequence and voltage ranges differs from device to device.

Move internal SPM driver structures to the driver itself, removing them

The SAW2 device can optionally provide a voltage regulator supplying the
CPU core, cluster or L2 cache. Change the boolean 'regulator' property
into a proper regulator description. This breaks schema compatibility
for the sake of properly describing the regulator.

Define compatible strings for SAW2 units present on MSM8960, IPQ4019
and IPQ8064. There is no need to include SAW version into the compat
string, so just use the SoC and SAW2 kind.
Also add missing L2 SAW2 compatibles for MSM8974 and APQ8084, they
follow the existing CPU SAW2 strings.

The Qualcomm SPM / SAW2 device is described in two bindigns files:
arm/msm/qcom,saw2.txt and soc/qcom/qcom,spm.yaml. Merge the former into
the latter, adding detailed device node description. While we are at it,
also rename qcom,spm.yaml to qcom,saw2.yaml to follow the actual
compatible used for these devices.
The regulator property is retained as is. It will be changed in the
later patches.

Commit c72ca343f911 ("soc: qcom: llcc: Add v4.1 HW version support")
introduced a new 4.1 if statement in llcc_update_act_ctrl() without
considering that ret might be overwritten. So, add return value check
after Broadcast_OR register read in llcc_update_act_ctrl().
