Geert Uytterhoeven fa43948f67 arm64: renesas: Move SoC Kconfig symbols to drivers/soc/renesas/
arch/arm64/Kconfig.platforms has SoC-specific Kconfig symbols for
Renesas SoCs, while other vendors have only a single Kconfig symbol.

Increase consistency with other vendors by moving the SoC-specific
Kconfig symbols to drivers/soc/renesas/Kconfig.

Increase consistency with R-Car Gen1 and Gen2 SoCs on arm32 by
introducing a family-specific Kconfig symbol for R-Car Gen3
(ARCH_RCAR_GEN3), which enables family-specific hardware features.
While so far only a single family (R-Car Gen3 and derivatives) of
Renesas arm64 SoCs is supported by Linux, this will make it easier
to add support for other SoC families later.

Maxime Jourdan 41bb5769b7 drivers: soc: Allow building the amlogic drivers without ARCH_MESON
The current condition makes it difficult to compile the amlogic/

Fixes kbuild errors with patch series that depend on drivers in that

Stephen Boyd ed3cafa79e soc: qcom: cmd-db: Stop memcpy()ing in cmd_db_read_aux_data()
Let's change the function signature to return the pointer to memory or
an error pointer on failure, and take an argument that lets us return
the size of the aux data read. This way we can remove the
cmd_db_read_aux_data_len() API entirely and also get rid of the memcpy
operation from cmd_db to the caller. Updating the only user of this code
shows that making this change allows us to remove a function and put the
lookup where the user is.

Stephen Boyd 84fa36eb30 soc: qcom: cmd-db: Remove memcpy()ing from cmd_db_get_header()
The cmd_db_get_header() function is a static local function that doesn't
need to copy anything from one place to another. Instead, it can just
point into the region by returning pointers to what we're looking for.
If we do that, we should mark what we're returning as const so that code
can't modify cmd-db without an obvious cast.

Marc Zyngier 832ad0e3da soc: ti: QMSS: Fix usage of irq_set_affinity_hint
The Keystone QMSS driver is pretty damaged, in the sense that it
does things like this:

	irq_set_affinity_hint(irq, to_cpumask(&cpu_map));

where cpu_map is a local variable. As we leave the function, this
will point to nowhere-land, and things will end-up badly.

Instead, let's use a proper cpumask that gets allocated, giving
the driver a chance to actually work with things like irqbalance
as well as have a hypothetical 64bit future.

Linus Torvalds b22b6beae6 ARM: SoC driver updates for 4.17
The most noteworthy SoC driver changes this time include:
 
 - The TEE subsystem gains an in-kernel interface to access the TEE
   from device drivers.
 
 - The reset controller subsystem gains a driver for the Qualcomm
   Snapdragon 845 Power Domain Controller.
 
 - The Xilinx Zynq platform now has a firmware interface for its
   platform management unit. This contains a firmware "ioctl" interface
   that was a little controversial at first, but the version we merged
   solved that by not exposing arbitrary firmware calls to user space.
 
 - The Amlogic Meson platform gains a "canvas" driver that is used
   for video processing and shared between different high-level drivers.
 
 The rest is more of the usual, mostly related to SoC specific power
 management support and core drivers in drivers/soc:
 
 - Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new
   features related to power and reset control.
 
 - The Mediatek mt8183 and mt6765 SoC platforms gain support for
   their respective power management chips.
 
 - A new driver for NXP i.MX8, which need a firmware interface for
   power management.
 
 - The SCPI firmware interface now contains support estimating power
   usage of performance states
 
 - The NVIDIA Tegra "pmc" driver gains a few new features, in particular
   a pinctrl interface for configuring the pads.
 
 - Lots of small changes for Qualcomm, in particular the "smem"
   device driver.
 
 - Some cleanups for the TI OMAP series related to their sysc
   controller.
 
 Additional cleanups and bugfixes in SoC specific drivers include the
 Meson, Keystone, NXP, AT91, Sunxi, Actions, and Tegra platforms.

Notable changes:
 
  - A large series to rewrite our SLB miss handling, replacing a lot of fairly
    complicated asm with much fewer lines of C.
 
  - Following on from that, we now maintain a cache of SLB entries for each
    process and preload them on context switch. Leading to a 27% speedup for our
    context switch benchmark on Power9.
 
  - Improvements to our handling of SLB multi-hit errors. We now print more debug
    information when they occur, and try to continue running by flushing the SLB
    and reloading, rather than treating them as fatal.
 
  - Enable THP migration on 64-bit Book3S machines (eg. Power7/8/9).
 
  - Add support for physical memory up to 2PB in the linear mapping on 64-bit
    Book3S. We only support up to 512TB as regular system memory, otherwise the
    percpu allocator runs out of vmalloc space.
 
  - Add stack protector support for 32 and 64-bit, with a per-task canary.
 
  - Add support for PTRACE_SYSEMU and PTRACE_SYSEMU_SINGLESTEP.
 
  - Support recognising "big cores" on Power9, where two SMT4 cores are presented
    to us as a single SMT8 core.
 
  - A large series to cleanup some of our ioremap handling and PTE flags.
 
  - Add a driver for the PAPR SCM (storage class memory) interface, allowing
    guests to operate on SCM devices (acked by Dan).
 
  - Changes to our ftrace code to handle very large kernels, where we need to use
    a trampoline to get to ftrace_caller().
 
 Many other smaller enhancements and cleanups.

   - Add a driver for the PAPR SCM (storage class memory) interface,
     allowing guests to operate on SCM devices (acked by Dan).

   - Changes to our ftrace code to handle very large kernels, where we
     need to use a trampoline to get to ftrace_caller().

  And many other smaller enhancements and cleanups.

- Sync dtc with upstream version v1.4.7-14-gc86da84d30e4
 
 - Work to get rid of direct accesses to struct device_node name and
   type pointers in preparation for removing them. New helpers for
   parsing DT cpu nodes and conversions to use the helpers. printk
   conversions to %pOFn for printing DT node names. Most went thru
   subystem trees, so this is the remainder.
 
 - Fixes to DT child node lookups to actually be restricted to child
   nodes instead of treewide.
 
 - Refactoring of dtb targets out of arch code. This makes the support
   more uniform and enables building all dtbs on c6x, microblaze, and
   powerpc.

 - Restructuring of some ARM binding docs moving some peripheral bindings
   out of board/SoC binding files
 
 - New "secure-chosen" binding for secure world settings on ARM

Linus Torvalds a978a5b8d8 net/kconfig: Make QCOM_QMI_HELPERS available when COMPILE_TEST
The networking merge brought in the experimental support for the
Qualcomm ath10k system NOC, which selects QCOM_QMI_HELPERS as a
dependency.

But the ATH10K_SNOC option (which selects QCOM_QMI_HELPERS) depends on
ARCH_QCOM || COMPILE_TEST in order to get wider build testing than just
the unusual QCOM architecture build, while the QCOM_QMI_HELPERS option
doesn't have that COMPILE_TEST option and is limited to only ARCH_QCOM.

As a result, a "make allmodconfig" complains

  WARNING: unmet direct dependencies detected for QCOM_QMI_HELPERS
    Depends on [n]: ARCH_QCOM && NET [=y]
    Selected by [m]:
    - ATH10K_SNOC [=m] && NETDEVICES [=y] && WLAN [=y] && WLAN_VENDOR_ATH [=y] && ATH10K [=m] && (ARCH_QCOM || COMPILE_TEST [=y])

Fix the config-time warning by making QCOM_QMI_HELPERS available when
COMPILE_TEST, since the result seems to build fine.

ioremap_prot() with flag set to 0 relies on a hack in

handed flags don't look like a valid set of flags
(ie don't include _PAGE_PRESENT)

patch renames all functions and structure definitions started

Laurentiu Tudor 853dc104e6 soc: fsl: qbman: add APIs to retrieve the probing status
Add a couple of new APIs to check the probing status of qman and bman:
 'int bman_is_probed()' and 'int qman_is_probed()'.
They return the following values.
 *  1 if qman/bman were probed correctly
 *  0 if qman/bman were not yet probed
 * -1 if probing of qman/bman failed
Drivers that use qman/bman driver services are required to use these
APIs before calling any functions exported by qman or bman drivers
or otherwise they will crash the kernel.
The APIs will be used in the following couple of qbman portal patches
and later in the series in the dpaa1 ethernet driver.

Douglas Anderson 969fc78c37 soc: qcom: geni: geni_se_clk_freq_match() should always accept multiples
The geni_se_clk_freq_match() has some strange semantics.  Specifically
it is defined with two modes:
1. It can find a clock that's an exact multiple of the requested rate
2. It can find a non-exact match but it can't handle multiples then

...but callers should always be able to handle a clock that is a
multiple of the requested clock so mode #2 doesn't really make sense.
Let's change the semantics so that the non-exact match can also accept
multiples and then change the code to handle that.

The only caller of this code is the unlanded SPI driver [1] which
currently passes "exact = True", thus it should be safe to change the
semantics in this way.  ...and, in fact, the SPI driver should likely
be modified to pass "exact = False" (with the new semantics) since
that will allow it to work with SPI devices that request a clock rate
that doesn't exactly match a rate we can make.

Douglas Anderson abc1c94471 soc: qcom: geni: Don't ignore clk_round_rate() errors in geni_se_clk_tbl_get()
The function clk_round_rate() is defined to return a "long", not an
"unsigned long".  That's because it might return a negative error
code.  Change the call in geni_se_clk_tbl_get() to check for errors.

While we're at it, get rid of a useless init of "freq".

NOTE: overall the idea that we should iterate over clk_round_rate() to
try to reconstruct a table already present in the clock driver is
questionable.  Specifically:
- This method relies on "clk_round_rate()" rounding up.
- This method only works if the table is sorted and has no duplicates.
...this patch doesn't try to fix those problems, it just makes the
error handling more correct.

Douglas Anderson 867d4aa701 soc: qcom: geni: geni_se_clk_freq_match() should always accept multiples
The geni_se_clk_freq_match() has some strange semantics.  Specifically
it is defined with two modes:
1. It can find a clock that's an exact multiple of the requested rate
2. It can find a non-exact match but it can't handle multiples then

...but callers should always be able to handle a clock that is a
multiple of the requested clock so mode #2 doesn't really make sense.
Let's change the semantics so that the non-exact match can also accept
multiples and then change the code to handle that.

The only caller of this code is the unlanded SPI driver [1] which
currently passes "exact = True", thus it should be safe to change the
semantics in this way.  ...and, in fact, the SPI driver should likely
be modified to pass "exact = False" (with the new semantics) since
that will allow it to work with SPI devices that request a clock rate
that doesn't exactly match a rate we can make.

Douglas Anderson e11bbcedec soc: qcom: geni: Don't ignore clk_round_rate() errors in geni_se_clk_tbl_get()
The function clk_round_rate() is defined to return a "long", not an
"unsigned long".  That's because it might return a negative error
code.  Change the call in geni_se_clk_tbl_get() to check for errors.

While we're at it, get rid of a useless init of "freq".

NOTE: overall the idea that we should iterate over clk_round_rate() to
try to reconstruct a table already present in the clock driver is
questionable.  Specifically:
- This method relies on "clk_round_rate()" rounding up.
- This method only works if the table is sorted and has no duplicates.
...this patch doesn't try to fix those problems, it just makes the
error handling more correct.

Olof Johansson 92f06c384b Allwinner drivers changes for 4.19
There's been work for this release cycles in both the SRAM controller
 driver in order to support more SoCs, as part of our VPU work, but also to
 enable the EMAC on the A64 (that needs to poke at registers within the same
 register space).
 
 Some work has been needed too to represent the bus to the display engine
 controllers that all need an SRAM to be mapped to the CPU to be able to
 access those controllers' registers.

    keeping the DISP domain always-on, because Upon resuming from power
    gating, the modules in the display power domain (eLCDIF, EPDC, PXP
    and SPDC) might fail to perform register reads correctly.
  - Use GENPD_FLAG_ALWAYS_ON flag for i.MX6QP PU ERR009619 handling.
    It is functionally identical to the exsiting implementation but

Olof Johansson b598b3aaf9 Second Round of Renesas ARM Based SoC Updates for v4.19
* Always enable ARCH_TIMER on SoCs with A7 or A15
 
   All such SoCs have ARCH_TIMER so there is no need for it to be optional.
   This allows clean-up which is included in this change.
 
 * Do not compile r8a7779_platform_cpu_kill when it is unused
 
   This avoids a warning by shuffling code into an existing #ifdef
   r8a7779 is the R-Car H1 SoC
 
 * Add SMP enabler driver for the RZ/N1D (r9a06g032) SoC

Second Round of Renesas ARM Based SoC Updates for v4.19

* Always enable ARCH_TIMER on SoCs with A7 or A15

  All such SoCs have ARCH_TIMER so there is no need for it to be optional.
  This allows clean-up which is included in this change.

* Do not compile r8a7779_platform_cpu_kill when it is unused

  This avoids a warning by shuffling code into an existing #ifdef
  r8a7779 is the R-Car H1 SoC

* Add SMP enabler driver for the RZ/N1D (r9a06g032) SoC

Lina Iyer 2de4b8d33e drivers: qcom: rpmh-rsc: allow active requests from wake TCS
Some RSCs may only have sleep and wake TCS, i.e, there is no dedicated
TCS for active mode request, but drivers may still want to make active
requests from these RSCs. In such cases re-purpose the wake TCS to send
active state requests.

The requirement for this is that the driver is aware that the wake TCS
is being repurposed to send active request, hence the sleep and wake
TCSes be invalidated before the active request is sent.

Lina Iyer c8790cb6da drivers: qcom: rpmh: add support for batch RPMH request
Platform drivers need make a lot of resource state requests at the same
time, say, at the start or end of an usecase. It can be quite
inefficient to send each request separately. Instead they can give the
RPMH library a batch of requests to be sent and wait on the whole
transaction to be complete.

rpmh_write_batch() is a blocking call that can be used to send multiple
RPMH command sets. Each RPMH command set is set asynchronously and the
API blocks until all the command sets are complete and receive their
tx_done callbacks.

Platform drivers that want to send a request but do not want to block
until the RPMH request completes have now a new API -
rpmh_write_async().

The API allocates memory and send the requests and returns the control
back to the platform driver. The tx_done callback from the controller is
handled in the context of the controller's thread and frees the
allocated memory. This API allows RPMH requests from atomic contexts as
well.

Active state requests are sent immediately to the RSC controller, while
sleep and wake state requests are cached in this driver to avoid taxing
the RSC controller repeatedly. The cached values will be sent to the
controller when the rpmh_flush() is called.

Generally, flushing is a system PM activity and may be called from the
system PM drivers when the system is entering suspend or deeper sleep
modes during cpuidle.

Also allow invalidating the cached requests, so they may be re-populated
again.

Sleep and wake requests are sent when the application processor
subsystem of the SoC is entering deep sleep states like in suspend.
These requests help lower the system power requirements when the
resources are not in use.

Sleep and wake requests are written to the TCS slots but are not
triggered at the time of writing. The TCS are triggered by the firmware
after the last of the CPUs has executed its WFI. Since these requests
may come in different batches of requests, it is the job of this
controller driver to find and arrange the requests into the available
TCSes.

Lina Iyer 658628e7ef drivers: qcom: rpmh-rsc: add RPMH controller for QCOM SoCs
Add controller driver for QCOM SoCs that have hardware based shared
resource management. The hardware IP known as RSC (Resource State
Coordinator) houses multiple Direct Resource Voter (DRV) for different
execution levels. A DRV is a unique voter on the state of a shared
resource. A Trigger Control Set (TCS) is a bunch of slots that can house
multiple resource state requests, that when triggered will issue those
requests through an internal bus to the Resource Power Manager Hardened
(RPMH) blocks. These hardware blocks are capable of adjusting clocks,
voltages, etc. The resource state request from a DRV are aggregated
along with state requests from other processors in the SoC and the
aggregate value is applied on the resource.

Some important aspects of the RPMH communication -
- Requests are <addr, value> with some header information
- Multiple requests (upto 16) may be sent through a TCS, at a time
- Requests in a TCS are sent in sequence
- Requests may be fire-n-forget or completion (response expected)
- Multiple TCS from the same DRV may be triggered simultaneously
- Cannot send a request if another request for the same addr is in
  progress from the same DRV
- When all the requests from a TCS are complete, an IRQ is raised
- The IRQ handler needs to clear the TCS before it is available for
  reuse
- TCS configuration is specific to a DRV
- Platform drivers may use DRV from different RSCs to make requests

Resource state requests made when CPUs are active are called 'active'
state requests. Requests made when all the CPUs are powered down (idle
state) are called 'sleep' state requests. They are matched by a
corresponding 'wake' state requests which puts the resources back in to
previously requested active state before resuming any CPU. TCSes are
dedicated for each type of requests. Active mode TCSes (AMC) are used to
send requests immediately to the resource, while control TCS are used to
provide specific information to the controller. Sleep and Wake TCS send
sleep and wake requests, after and before the system halt respectively.

"always on" instead the pm core won't even attempt to turn it off.

In theory on 6qp it is safe to turn PU off in suspend, however that is
best accomplished with a new core flag.

Argus Lin 8e62ac4bad soc: mediatek: pwrap: add pwrap driver for mt6797 SoCs
mt6797 is a highly integrated SoCs, it uses mt6351 for power management.
This patch adds pwrap driver to access mt6351. Pwrap of mt6797 support
dynamic priority meichanism, sequence monitor and starvation mechanism
to make transaction more reliable.

A big change from V4 to V5 is we remove INT1 interrupt declaration since
it is only for debug purpose. The PWRAP_RDDMY, RESET and DCM can use legacy
setting, it is backwards compatible. The new caps flag declaration is not
needed, just remove it.

* Convert to SPDX identifier
 
 * Remove legacy SMP fallback code
 
   Geert Uytterhoeven says "R-Car H2 and M2-W have been supporting SMP
   enablement from DT using the "renesas,apmu" enable-method since v4.8.
   A legacy fallback was left in place for backwards compatibility with old
   DTBs.
 
   This patch series removes the legacy SMP fallbacks for R-Car H2 and
   M2-W, and consolidates their support in the common R-Car Gen2 machine
   definition.2
 
 * APMU cleanups after legacy SMP fallback removal
   - Move cpu_leave_lowpower() from HOTPLUG_CPU || SUSPEND section to the
     SUSPEND section as it is only used for suspend
   - Remove shmobile_smp_apmu_prepare_cpus() as it is no longer used
   - Remove platsmp-apmu.h
 
 * Drop legacy SYSC fallbacks
 
   Geert Uytterhoeven says "When DT SYSC support was introduced in v4.7,
   legacy fallbacks were kept to keep secondary CPUs working on R-Car H1,
   H2, and M2-W using old DTBs.  However, the time has come to drop these
   fallbacks, and clean up the resulting code"

Arnd Bergmann 0ea3fa15b1 qcom: cmd-db: enforce CONFIG_OF_RESERVED_MEM dependency
Without CONFIG_OF_RESERVED_MEM, gcc sees that the global cmd_db_header
variable is never initialized, and through code optimization concludes
that a lot of other code cannot possibly work after that:

Using a hard CONFIG_OF_RESERVED_MEM dependency avoids this warning,
and we can remove the CONFIG_OF dependency.

The SRAM mapping controls on Allwinner SoCs is located in a block called
"System Controls". This block also has registers for identifying the SoC,
reading the state of an external boot-related pin, and on some newer SoCs,
glue layer controls for the EMAC Ethernet controller.

The A64 variant compatible is renamed to "allwinner,a64-system-control"
to reflect this. The old A64 compatible is deprecated. So far we haven't
seen any actual use of it.

Merge tag 'overflow-v4.18-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

Pull more overflow updates from Kees Cook:
 "The rest of the overflow changes for v4.18-rc1.

  This includes the explicit overflow fixes from Silvio, further
  struct_size() conversions from Matthew, and a bug fix from Dan.

  But the bulk of it is the treewide conversions to use either the
  2-factor argument allocators (e.g. kmalloc(a * b, ...) into
  kmalloc_array(a, b, ...) or the array_size() macros (e.g. vmalloc(a *
  b) into vmalloc(array_size(a, b)).

  Coccinelle was fighting me on several fronts, so I've done a bunch of
  manual whitespace updates in the patches as well.

  Summary:

   - Error path bug fix for overflow tests (Dan)

   - Additional struct_size() conversions (Matthew, Kees)

   - Explicitly reported overflow fixes (Silvio, Kees)

   - Add missing kvcalloc() function (Kees)

   - Treewide conversions of allocators to use either 2-factor argument
     variant when available, or array_size() and array3_size() as needed
     (Kees)"

Kees Cook fad953ce0b treewide: Use array_size() in vzalloc()
The vzalloc() function has no 2-factor argument form, so multiplication
factors need to be wrapped in array_size(). This patch replaces cases of:

        vzalloc(a * b)

with:
        vzalloc(array_size(a, b))

as well as handling cases of:

        vzalloc(a * b * c)

with:

        vzalloc(array3_size(a, b, c))

This does, however, attempt to ignore constant size factors like:

        vzalloc(4 * 1024)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

The Coccinelle script used for this was:

Kees Cook a86854d0c5 treewide: devm_kzalloc() -> devm_kcalloc()
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc().
This patch replaces cases of:

        devm_kzalloc(handle, a * b, gfp)

with:
        devm_kcalloc(handle, a * b, gfp)

as well as handling cases of:

        devm_kzalloc(handle, a * b * c, gfp)

with:

        devm_kzalloc(handle, array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        devm_kcalloc(handle, array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        devm_kzalloc(handle, 4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

Some manual whitespace fixes were needed in this patch, as Coccinelle
really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".

The Coccinelle script used for this was:

The kmalloc() function has a 2-factor argument form, kmalloc_array(). This
patch replaces cases of:

        kmalloc(a * b, gfp)

with:
        kmalloc_array(a * b, gfp)

as well as handling cases of:

        kmalloc(a * b * c, gfp)

This does, however, attempt to ignore constant size factors like:

        kmalloc(4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

Linus Torvalds 8efcf34a26 ARM: SoC: late updates
This is a branch with a few merge requests that either came in late, or
 took a while longer for us to review and merge than usual and thus cut
 it a bit close to the merge window. We stage them in a separate branch
 and if things look good, we still send them up -- and that's the case
 here.
 
 This is mostly DT additions for Renesas platforms, adding IP block
 descriptions for existing and new SoCs.
 
 There are also some driver updates for Qualcomm platforms for SMEM/QMI
 and GENI, which is their generalized serial protocol interface.

 "This is a branch with a few merge requests that either came in late,
  or took a while longer for us to review and merge than usual and thus
  cut it a bit close to the merge window. We stage them in a separate
  branch and if things look good, we still send them up -- and that's
  the case here.

  This is mostly DT additions for Renesas platforms, adding IP block
  descriptions for existing and new SoCs.

  There are also some driver updates for Qualcomm platforms for SMEM/QMI
  and GENI, which is their generalized serial protocol interface"

Linus Torvalds 7c00e8ae04 ARM: SoC platform updates
Here are the main updates for SoC support (besides DT additions) for ARM
 32- and 64-bit platforms. The branch also contains defconfig updates to
 turn on drivers and options as needed on the various platforms.
 
 The largest parts of the delta are from cleanups moving platform data
 and board file setup of TI platforms to ti-sysc bus drivers. There are
 also some sweeping changes of eeprom and nand setup on Davinci, i.MX
 and other platforms.
 
 Samsung is removing support for Exynos5440, which was an oddball SoC
 that hasn't been seen much use in designs.
 
 Renesas is adding support for new SoCs (R-Car E3, RZ/G1C and RZ/N1D).
 
 Linus Walleij is also removing support for ux500 (Sony Ericsson)
 U8540/9540 SoCs that never made it to significant mass production and
 products.

Linus Torvalds 6419945e33 This time we have a good set of changes to the core framework that do some
general cleanups, but nothing too major. The majority of the diff goes to
 two SoCs, Actions Semi and Qualcomm. A brand new driver is introduced for
 Actions Semi so it takes up some lines to add all the different types, and
 the Qualcomm diff is there because we add support for two SoCs and it's quite
 a bit of data.
 
 Otherwise the big driver updates are on TI Davinci and Amlogic platforms. And
 then the long tail of driver updates for various fixes and stuff follows
 after that.
 
 Core:
  - debugfs cleanups removing error checking and an unused provider API
  - Removal of a clk init typedef that isn't used
  - Usage of match_string() to simplify parent string name matching
  - OF clk helpers moved to their own file (linux/of_clk.h)
  - Make clk warnings more readable across kernel versions
 
 New Drivers:
  - Qualcomm SDM845 GCC and Video clk controllers
  - Qualcomm MSM8998 GCC
  - Actions Semi S900 SoC support
  - Nuvoton npcm750 microcontroller clks
  - Amlogic axg AO clock controller
 
 Removed Drivers:
  - Deprecated Rockchip clk-gate driver
 
 Updates:
  - debugfs functions stopped checking return values
  - Support for the MSIOF module clocks on Rensas R-Car M3-N
  - Support for the new Rensas RZ/G1C and R-Car E3 SoCs
  - Qualcomm GDSC, RCG, and PLL updates for clk changes in new SoCs
  - Berlin and Amlogic SPDX tagging
  - Usage of of_clk_get_parent_count() in more places
  - Proper implementation of the CDEV1/2 clocks on Tegra20
  - Allwinner H6 PRCM clock support and R40 EMAC support
  - Add critical flag to meson8b's fdiv2 as temporary fixup for ethernet

Geert Uytterhoeven 977d5ba450 soc: renesas: rcar-sysc: Make PM domain initialization more robust
The quirk for R-Car E3 ES1.0 added in commit 086b399965 ("soc:
renesas: r8a77990-sysc: Add workaround for 3DG-{A,B}") makes the 3DG-A
PM domain a subdomain of the 3DG-B PM domain.  However, registering
3DG-A with its parent fails silently, as the 3DG-B PM domain hasn't been
registered yet, and such failures are never reported.

Fix this by:
  1. Splitting PM Domain initialization in two steps, so all PM domains
     are registered before any child-parent links are established,
  2. Reporting any failures in establishing child-parent relations.

Check for and report pm_genpd_init() failures, too, as that function
gained a return value in commit 7eb231c337 ("PM / Domains: Convert
pm_genpd_init() to return an error code").

Fixes: 086b399965 ("soc: renesas: r8a77990-sysc: Add workaround for 3DG-{A,B}")

Merge tag 'overflow-v4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

Pull overflow updates from Kees Cook:
 "This adds the new overflow checking helpers and adds them to the
  2-factor argument allocators. And this adds the saturating size
  helpers and does a treewide replacement for the struct_size() usage.
  Additionally this adds the overflow testing modules to make sure
  everything works.

  I'm still working on the treewide replacements for allocators with
  "simple" multiplied arguments:

     *alloc(a * b, ...) -> *alloc_array(a, b, ...)

  and

     *zalloc(a * b, ...) -> *calloc(a, b, ...)

  as well as the more complex cases, but that's separable from this
  portion of the series. I expect to have the rest sent before -rc1
  closes; there are a lot of messy cases to clean up.

  Summary:

   - Introduce arithmetic overflow test helper functions (Rasmus)

   - Use overflow helpers in 2-factor allocators (Kees, Rasmus)

   - Introduce overflow test module (Rasmus, Kees)

   - Introduce saturating size helper functions (Matthew, Kees)

   - Treewide use of struct_size() for allocators (Kees)"

     used on Renesas R-Car SoCs only.  Since commit 9b5ba0df4e ("ARM:
     shmobile: Introduce ARCH_RENESAS") is ARCH_RENESAS a more appropriate
     platform dependency than the legacy ARCH_SHMOBILE, hence use the
     former.
 
     This will allow to drop ARCH_SHMOBILE on ARM and ARM64 in the near
     future."
 
   - Add the to Kconfig RZ/N1D (r9a06g032) SoC
 
     In preparation for upstream support of this SoC
 
   - Identify R-Car E3 (r8a77990) SoC
 
   - Identify and add minimal support for RZ/G1C (r8a77470) SoC
 
 * R-Car SYSC
   - Add support for R-Car E3 (r8a77990) SoC
 
     Shimoda-san says this adds:
     + "Cortex-A53 CPU{0,1}, Cortex-A53 SCU, Cortex-R7, A3VC,
        A2VC1 and 3DG-{A,B} power domain areas..."
 
     + "workaround for 3DG-{A,B} of R-Car E3 ES1.0 because
        the SoC has a restriction about the order."
 
   - Remove unused inclusion of <linux/sys_soc.h>,
 
   - Make r8a77995_areas[] const.

Alex Elder 7df5ff258b soc: qcom: qmi: fix a buffer sizing bug
In qmi_handle_init(), a buffer is allocated for to hold messages
received through the handle's socket.  Any "normal" messages
(expected by the caller) will have a header prepended, so the
buffer size is adjusted to accomodate that.

The buffer must also be of sufficient size to receive control
messages, so the size is increased if necessary to ensure these
will fit.

Unfortunately the calculation is done wrong, making it possible
for the calculated buffer size to be too small to hold a "normal"
message.  Specifically, if:

  recv_buf_size > sizeof(struct qrtr_ctrl_pkt) - sizeof(struct qmi_header)
		AND
  recv_buf_size < sizeof(struct qrtr_ctrl_pkt)

the current logic will use sizeof(struct qrtr_ctrl_pkt) as the
receive buffer size, which is not enough to hold the maximum
"normal" message plus its header.  Currently this problem occurs
for (13 < recv_buf_size < 20).

This patch corrects this.

Cached items are found at the high end of an smem partition.  A

The address of the structure describing the first cached item should

MT7622_POWER_DOMAIN_WB doesn't send an ACK when its managed SRAM becomes
stable, which is not like the behavior the other power domains should
have. Therefore, it's necessary for such a power domain to have a fixed

to access by all functions running on the top.

This patch provide APIs to allow client drivers to support
probe deferral. On K2G SoC, devices can be probed only
after the ti_sci_pm_domains driver is probed and ready.
As drivers may get probed at different order, any driver
that depends on knav dma and qmss drivers, for example
netcp network driver, needs to defer probe until
knav devices are probed and ready to service. To do this,
add an API to query the device ready status from the knav
dma and qmss devices.

version of QMSS with less number of queues, internal linking ram
with lesser number of buffers etc.  It doesn't have status and
explicit push register space as in QMSS available on other K2 SoCs.
So define reg indices specific to QMSS on K2G. This patch introduces
"ti,66ak2g-navss-qm" compatibility to identify QMSS on K2G NAVSS
and to customize the dts handling code. Per Device manual,
descriptors with index less than or equal to regions0_size is in region 0
in the case of K2 QMSS where as for QMSS on K2G, descriptors with index
less than regions0_size is in region 0. So update the size accordingly in
the regions0_size bits of the linking ram size 0 register.
