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

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.

Navigator Subsystem (NAVSS) available on K2G SoC has a cut down
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.

Pull clk updates from Stephen Boyd:
"The large diff this time around is from the addition of a new clk
driver for the TI Davinci family of SoCs. So far those clks have been
supported with a custom implementation of the clk API in the arch port
instead of in the CCF. With this driver merged we're one step closer
to having a single clk API implementation.
The other large diff is from the Amlogic clk driver that underwent
some major surgery to use regmap. Beyond that, the biggest hitter is
Samsung which needed some reworks to properly handle clk provider
power domains and a bunch of PLL rate updates.
The core framework was fairly quiet this round, just getting some
cleanups and small fixes for some of the more esoteric features. And
the usual set of driver non-critical fixes, cleanups, and minor
additions are here as well.
Core:
- Rejig clk_ops::init() to be a little earlier for phase/accuracy ops
- debugfs ops macroized to shave some lines of boilerplate code
- Always calculate the phase instead of caching it in clk_get_phase()
- More __must_check on bulk clk APIs
New Drivers:
- TI's Davinci family of SoCs
- Intel's Stratix10 SoC
- stm32mp157 SoC
- Allwinner H6 CCU
- Silicon Labs SI544 clock generator chip
- Renesas R-Car M3-N and V3H SoCs

- STM32F469 DSI and STM32F769 sdmmc2 support
- GPIO clks can sleep now
- Spreadtrum SC9860 RTC clks
- Nvidia Tegra MBIST workarounds and various minor fixes
- Rockchip phase handling fixes and a memory leak plugged
- Renesas drivers switch to readl/writel from clk_readl/clk_writel
- Renesas gained CPU (Z/Z2) and watchdog support
- Rockchip rk3328 display clks and rk3399 1.6GHz PLL support

01d675f159 ARM: shmobile: rcar-gen2: Add watchdog support
58adf1ba0d ARM: shmobile: Add watchdog support
* SoC
- Identify R-Car V3H (r8a77980) and M3N (r8a77965)
- Enable R-Car Gen2 regulator quirk for Stout board with H3 (r8a7790) SoC
Marek Vaust says "Regulator setup is suboptimal on H2 Stout too. The
Stout newly has two DA9210 regulators, so the quirk is extended to
handle another DA9210 at i2c address 0x70."
- Add watchdog support
This is the SoC portion of the following solution. It is not yet
enabled in DT as it is not functional without clock dependencies
in place.
Fabrizio Castro says "this series has been around for some time as RFC,
and it has collected useful comments from the community along the way.
The solution proposed by this patch set works for most R-Car Gen2 and
RZ/G1 devices, but not all of them. We now know that for some R-Car
Gen2 early revisions there is no proper software fix. Anyway, no
product has been built around early revisions, but development boards
mounting early revisions (basically prototypes) are still out there.
As a result, this series isn't enabling the internal watchdog on R-Car
Gen2 boards, developers may enable it in board specific device trees if
needed. This series has been tested by me on the iwg20d, iwg22d,
Lager, Alt, and Koelsch boards.
The problem
===========
To deal with SMP on R-Car Gen2 and RZ/G1, we install a reset vector to
ICRAM1 and we program the [S]BAR registers so that when we turn ON the
non-boot CPUs they are redirected to the reset vector installed by Linux
in ICRAM1, and eventually they continue the execution to RAM, where the
SMP bring-up code will take care of the rest. The content of the [S]BAR
registers survives a watchdog triggered reset, and as such after the
watchdog fires the boot core will try and execute the SMP bring-up code
instead of jumping to the bootrom code.
The fix
=======
The main strategy for the solution is to let the reset vector decide if
it needs to jump to shmobile_boot_fn or to the bootrom code. In a
watchdog triggered reset scenario, since the [S]BAR registers keep their
values, the boot CPU will jump into the newly designed reset vector, the
assembly routine will eventually test WOVF (a bit in register RWTCSRA
that indicates if the watchdog counter has overflown, the value of this
bit gets retained in this scenario), and jump to the bootrom code which
will in turn load up the bootloader, etc. When bringing up SMP or using
CPU hotplug, the reset vector will jump to shmobile_boot_fn instead."
* R-Car Rst
- Add support for R-Car V3H (r8a77980) and V3H (r8a77980)

Geert Uytterhoeven says "This frees another 1764 bytes
(arm32/shmobile_defconfig) or 1000 bytes (arm64/renesas_defconfig) of
memory after kernel init."
- Fix power area parents
Sergei Shtylyov says "According to the figure 9.2(b) of the R-Car
Series, 3rd Generation User’s Manual: Hardware Rev. 0.80 the A2IRn and
A2SCn power areas in R8A77970 have the A3IR area as a parent, thus the

Fun set of conflict resolutions here...
For the mac80211 stuff, these were fortunately just parallel
adds. Trivially resolved.
In drivers/net/phy/phy.c we had a bug fix in 'net' that moved the
function phy_disable_interrupts() earlier in the file, whilst in
'net-next' the phy_error() call from this function was removed.
In net/ipv4/xfrm4_policy.c, David Ahern's changes to remove the
'rt_table_id' member of rtable collided with a bug fix in 'net' that
added a new struct member "rt_mtu_locked" which needs to be copied
over here.
The mlxsw driver conflict consisted of net-next separating
the span code and definitions into separate files, whilst
a 'net' bug fix made some changes to that moved code.
The mlx5 infiniband conflict resolution was quite non-trivial,
the RDMA tree's merge commit was used as a guide here, and
here are their notes:
====================
Due to bug fixes found by the syzkaller bot and taken into the for-rc
branch after development for the 4.17 merge window had already started
being taken into the for-next branch, there were fairly non-trivial
merge issues that would need to be resolved between the for-rc branch
and the for-next branch. This merge resolves those conflicts and
provides a unified base upon which ongoing development for 4.17 can
be based.
Conflicts:
drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f95
(IB/mlx5: Fix cleanup order on unload) added to for-rc and
commit b5ca15ad7e (IB/mlx5: Add proper representors support)
add as part of the devel cycle both needed to modify the
init/de-init functions used by mlx5. To support the new
representors, the new functions added by the cleanup patch
needed to be made non-static, and the init/de-init list
added by the representors patch needed to be modified to
match the init/de-init list changes made by the cleanup
patch.
Updates:
drivers/infiniband/hw/mlx5/mlx5_ib.h - Update function
prototypes added by representors patch to reflect new function
names as changed by cleanup patch
drivers/infiniband/hw/mlx5/ib_rep.c - Update init/de-init
stage list to match new order from cleanup patch

Add SCPSYS power domain driver for MT7623A SoC. The MT7623A's power
domains are the subset of MT7623 SoC's ones. As MT7623 SoC has full
features whereas MT7623A is being designed just for router applications.
Thus, MT7623A doesn't include those power domains multimedia function

registering those power domains on MT7623A SoC using the existing MT7623
