These are all the driver updates for SoC specific drivers. There
are a couple of subsystems with individual maintainers picking up
their patches here:
- The reset controller subsystem add support for a few new SoC
variants to existing drivers, along with other minor improvements
- The OP-TEE subsystem gets a driver for the ARM FF-A transport
- The memory controller subsystem has improvements for Tegra,
Mediatek, Renesas, Freescale and Broadcom specific drivers.
- The tegra cpuidle driver changes get merged through this
tree this time. There are only minor changes, but they depend
on other tegra driver updates here.
- The ep93xx platform finally moves to using the drivers/clk/
subsystem, moving the code out of arch/arm in the process.
This depends on a small sound driver change that is included
here as well.
- There are some minor updates for Qualcomm and Tegra specific
firmware drivers.
The other driver updates are mainly for drivers/soc, which contains
a mixture of vendor specific drivers that don't really fit elsewhere:
- Mediatek drivers gain more support for MT8192, with new support for
hw-mutex and mmsys routing, plus support for reset lines in the
mmsys driver.
- Qualcomm gains a new "sleep stats" driver, and support for
the "Generic Packet Router" in the APR driver.
- There is a new user interface for routing the UARTS on ASpeed
BMCs, something that apparently nobody else has needed so far.
- More drivers can now be built as loadable modules, in particular
for Broadcom and Samsung platforms.
- Lots of improvements to the TI sysc driver for better suspend/resume
support
Finally, there are lots of minor cleanups and new device IDs for
amlogic, renesas, tegra, qualcomm, mediateka, samsung, imx, layerscape,
allwinner, broadcom, and omap.

The general expectation is that powering on a power-domain should make
the power domain deliver some power, and if a specific performance state
is needed further requests has to be made.
But in contrast with other power-domain implementations (e.g. rpmpd) the
RPMh does not have an interface to enable the power, so the driver has
to vote for a particular corner (performance level) in rpmh_power_on().
But the corner is never initialized, so a typical request to simply
enable the power domain would not actually turn on the hardware. Further
more, when no more clients vote for a performance state (i.e. the
aggregated vote is 0) the power domain would be turned off.
Fix both of these issues by always voting for a corner with non-zero
value, when the power domain is enabled.
The tracking of the lowest non-zero corner is performed to handle the
corner case if there's ever a domain with a non-zero lowest corner, in
which case both rpmh_power_on() and rpmh_rpmhpd_set_performance_state()
would be allowed to use this lowest corner.

Practically all modern Qualcomm platforms has a single reserved-memory
region for SMEM. So rather than having to describe SMEM in the form of a
node with a reference to a reserved-memory node, allow the SMEM device
to be instantiated directly from the reserved-memory node.
The current means of falling back to dereferencing the "memory-region"
is kept as a fallback, if it's determined that the SMEM node is a
reserved-memory node.
The "qcom,smem" compatible is added to the reserved_mem_matches list, to
allow the reserved-memory device to be probed.
In order to retain the readability of the code, the resolution of
resources is split from the actual ioremapping.

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.

In commit a871be6b8e ("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.

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 SMSM driver detects interrupt edges by tracking the last state
it has seen (and has triggered the interrupt handler for). This works
fine, but only if the interrupt does not change state while masked.
For example, if an interrupt is unmasked while the state is HIGH,
the stored last_value for that interrupt might still be LOW. Then,
when the remote processor triggers smsm_intr() we assume that nothing
has changed, even though the state might have changed from HIGH to LOW.
Attempt to fix this by checking the current remote state before
unmasking an IRQ. Use atomic operations to avoid the interrupt handler
from interfering with the unmask function.
This fixes modem crashes in some edge cases with the BAM-DMUX driver.
Specifically, the BAM-DMUX interrupt handler is not called for the
HIGH -> LOW smsm state transition if the BAM-DMUX driver is loaded
(and therefore unmasks the interrupt) after the modem was already started:

At the moment there is no way for drivers to get the current state
of the interrupt signal reported by a remote processor. The irqchip
API has generic functionality for this, using irq_get_irqchip_state().
Implement support for getting the IRQCHIP_STATE_LINE_LEVEL by reading
the remote state and checking the bit for the specified IRQ.

In __qcom_mdt_load() there are cases where an error occurs that
cause a message to be printed. In some of those cases the errno
value can be helpful to understand exactly what caused the problem.
Print the errno (as well as the firmware file name) where it is
helpful, and in a few cases reword the error message. Consistently
use the private fw_name for the file name.

Let's delete the private function cpr_read_efuse() since it does the
basically the same thing as the new API call
nvmem_cell_read_variable_le_u32().
Differences between the new API call and the old private function:
* less error printing (I assume this is OK).
* will give an error if the value doesn't fit in 32-bits (the old code
would have truncated silently).

The driver core ignores the return value of this callback because there
is only little it can do when a device disappears.
This is the final bit of a long lasting cleanup quest where several
buses were converted to also return void from their remove callback.
Additionally some resource leaks were fixed that were caused by drivers
returning an error code in the expectation that the driver won't go
away.
With struct bus_type::remove returning void it's prevented that newly
implemented buses return an ignored error code and so don't anticipate
wrong expectations for driver authors.
