strcpy() performs no bounds checking on the destination buffer. This
could result in linear overflows beyond the end of the buffer, leading
to all kinds of misbehaviors. The safe replacement is strscpy().
This is a previous step in the path to remove the strcpy() function
entirely from the kernel.

In commit a871be6b8eee ("cpuidle: Convert Qualcomm SPM driver to a generic
CPUidle driver") the SPM driver has been converted to a
generic CPUidle driver: that was mainly made to simplify the
driver and that was a great accomplishment;
Though, at that time, this driver was only applicable to ARM 32-bit SoCs,
lacking logic about the handling of newer generation SAW.
In preparation for the enablement of SPM features on AArch64/ARM64,
split the cpuidle-qcom-spm driver in two: the CPUIdle related
state machine (currently used only on ARM SoCs) stays there, while
the SPM communication handling lands back in soc/qcom/spm.c and
also making sure to not discard the simplifications that were
introduced in the aforementioned commit.
Since now the "two drivers" are split, the SCM dependency in the
main SPM handling is gone and for this reason it was also possible
to move the SPM initialization early: this will also make sure that
whenever the SAW CPUIdle driver is getting initialized, the SPM
driver will be ready to do the job.
Please note that the anticipation of the SPM initialization was
also done to optimize the boot times on platforms that have their
CPU/L2 idle states managed by other means (such as PSCI), while
needing SAW initialization for other purposes, like AVS control.

soc/tegra: Changes for v5.16-rc1
This set consists of stub additions to enable compile testing for more
drivers, exposes the PMC's USB regmap on all SoC generations, removes a
state synchronization workaround that is no longer needed and adds an
error reporting driver that can help troubleshoot crashes.
To top it all off, an error handling path in the powergating code is
fixed and the devm_platform_ioremap_resource() function is used to
remove some boilerplate code.

Qualcomm Generic Packet router aka GPR is the IPC mechanism found
in AudioReach next generation signal processing framework to perform
command and response messages between various processors.
GPR has concepts of static and dynamic port, all static services like
APM (Audio Processing Manager), PRM (Proxy resource manager) have
fixed port numbers where as dynamic services like graphs have dynamic
port numbers which are allocated at runtime. All GPR packet messages
will have source and destination domain and port along with opcode
and payload.

APR and other packet routers like GPR are pretty much same and
interact with other drivers in similar way.
Ex: GPR ports can be considered as APR services, only difference
is they are allocated dynamically.
Other difference is packet layout, which should not matter
with the apis abstracted. Apart from this the rest of the
functionality is pretty much identical across APR and GPR.
Make the apr code more reusable by abstracting it service level,
rather than device level so that we do not need to write
new drivers for other new packet routers like GPR.
This patch is in preparation to add GPR support to this driver.

Use the generic dynamic interrupt moderation (dim) framework to
implement adaptive interrupt coalescing on Rx. With the per-packet
interrupt scheme, a high interrupt rate has been noted for moderate
traffic flows leading to high CPU utilization.
The dpio driver exports new functions to enable/disable adaptive IRQ
coalescing on a DPIO object, to query the state or to update Net DIM
with a new set of bytes and frames dequeued.

In DPAA2 based SoCs, the IRQ coalesing support per software portal has 2
configurable parameters:
- the IRQ timeout period (QBMAN_CINH_SWP_ITPR): how many 256 QBMAN
cycles need to pass until a dequeue interrupt is asserted.
- the IRQ threshold (QBMAN_CINH_SWP_DQRR_ITR): how many dequeue
responses in the DQRR ring would generate an IRQ.
Add support for setting up and querying these IRQ coalescing related
parameters.

Through the dpio_get_attributes() firmware call the dpio driver has
access to the QBMAN clock frequency. Extend the structure which holds
the firmware's response so that we can have access to this information.
This will be needed in the next patches which also add support for
interrupt coalescing which needs to be configured based on the
frequency.

Fixes for omaps for v5.15
Few regression fixes for omaps for the v5.15-rc cycle. There is a fix
for boot time hangs that can happen on some am335x devices that started
when the pruss devicetree nodes were added. The other fixes are less
critical:
- Fix compiler warning for sysc_init_soc() that got recently introduced
- Fix external abort for am335x pruss as otherwise some am335x will hang
- Use CLKDM_NOAUTO quirk also for dra7 dcan1
- Fix older NAND device node regression for omap3-sdp

Starting with v5.15-rc1, we may now see some am335x beaglebone black
device produce the following error on pruss probe:
Unhandled fault: external abort on non-linefetch (0x1008) at 0xe0326000
This has started with the enabling of pruss for am335x in the dts files.
Turns out the is caused by the PRM reset handling not waiting for the
reset bit to clear. To fix the issue, let's always wait for the reset
bit to clear, even if there is a separate reset status register.
We attempted to fix a similar issue for dra7 iva with a udelay() in
commit effe89e40037 ("soc: ti: omap-prm: Fix occasional abort on reset
deassert for dra7 iva"). There is no longer a need for the udelay()
for dra7 iva reset either with the check added for reset bit clearing.

PT_LOAD type denotes that the segment should be loaded into the final
firmware memory region. Hash segment is not one such, because it's only
needed for PAS init and shouldn't be in the final firmware memory region.
That's why mdt_phdr_valid() explicitly reject non PT_LOAD segment and
hash segment. This actually makes the hash segment type check in
qcom_mdt_read_metadata() unnecessary and redundant. For a hash segment,
it won't be loaded into firmware memory region anyway, due to the
QCOM_MDT_TYPE_HASH check in mdt_phdr_valid(), even if it has a PT_LOAD
type for some reason (misusing or abusing?).
Some firmware files on Sony phones are such examples, e.g WCNSS firmware
of Sony Xperia M4 Aqua phone. The type of hash segment is just PT_LOAD.
Drop the unnecessary hash segment type check in qcom_mdt_read_metadata()
to fix firmware loading failure on these phones, while hash segment is
still kept away from the final firmware memory region.

The io-domain registers on RK3568 SoCs have three separated bits to
enable/disable the 1.8v/2.5v/3.3v power.
This patch make the write to be a operation, allow rk3568 uses a private
register set function.
Since the 2.5v mode hasn't been fully validated yet, the driver only sets
1.8v [enable] + 3.3v [disable] for 1.8v mode
1.8v [disable] + 3.3v [enable] for 3.3v mode
There is not register order requirement which has been cleared by our IC
team.
For future reference the full usage matrix including the 2.5V setting is:
case V33 V25 V18 result
0 0 0 0 IO safe, but cannot work
1 0 0 1 IO require 1.8V, should < 1.98V, otherwise IO may damage
2 0 1 0 IO require 2.5V, should < 2.75V, otherwise IO may damage
3 0 1 1 Invalid state, should avoid
4 1 0 0 IO require 3.3V, should < 3.63V, otherwise IO may damage
5 1 0 1 IO require 1.8V, should < 1.98V, otherwise IO may damage
6 1 1 0 IO require 2.5V, should < 2.75V, otherwise IO may damage
7 1 1 1 Invalid state, should avoid
