Now that we can dynamically switch between contiguous memory and
SG table depending on the trace buffer size, provide the support
for selecting an appropriate buffer size.

We are about to add the support for ETR builtin scatter-gather mode
for dealing with large amount of trace buffers. However, on some of
the platforms, using the ETR SG mode can lock up the system due to
the way the ETR is connected to the memory subsystem.
In SG mode, the ETR performs READ from the scatter-gather table to
fetch the next page and regular WRITE of trace data. If the READ
operation doesn't complete(due to the memory subsystem issues,
which we have seen on a couple of platforms) the trace WRITE
cannot proceed leading to issues. So, we by default do not
use the SG mode, unless it is known to be safe on the platform.
We define a DT property for the TMC node to specify whether we
have a proper SG mode.

were for B2.2 and later MEMSYS cores. Fall back to the previous S2/S3

As always, a large number of DT updates. Too many to enumerate them all,
but at a glance:
New SoCs introduced in this release:
- Amlogic:
+ Meson 8M2 SoC, a.k.a. S812. A quad Cortex-A9 SoC used in some set
top boxes and other products.
- Mediatek:
+ MT7623A, which is a flavor of the MT7623 family with other on-chip
ethernet options.
- Qualcomm:
+ SDM845, a.k.a Snapdragon 845, an 4+4-core Kryo 385/845
(Cortex-A75/A55 derivative) SoC that's one of the current high-end
mobile SoCs.
It's great to see mainline support for it. So far, you
can't do much with it, since a lot of peripherals are not yet in the
DTs but driver support for USB, GPU and other pieces are starting to
trickle in. This might end up being a well-supported SoC upstream if
the momentum keeps up.
- Renesas:
+ R8A77990, a.k.a R-Car E3, a new automotive entertainment-targeted
SoC. Currently only one Cortex-A53 CPU is enabled, we are eagerly
awaiting more. So far, basic drivers such as serial, gpios, PMU and
ethernet are enabled.
+ R8A77470, a.k.a. RZ/G1C, a new dual Cortex-A7 SoC with PowerVR
GPU. Same here, basic set of drivers such as serial, gpios and ethernet
enabled, and SMP support is also forthcoming.
- STMicroelectronics:
+ STM32F469, very similar tih STM32F429 but with display support
Enhancements to SoCs/platforms (DTS contents, some driver portions might
not be in yet):
- Allwinner sun8i (h3/a33/a83t) SMP, DVFS tweaks, misc
- Amlogic Meson: I2C, UFS, TDM, GPIO external interrupts, MMC resets
- Hisilicon hi3660: Thermal cooling, CPU frequency scaling, mailbox interfaces
- Marvell Berlin2CD: SMP support, thermal sensors
- Mediatek MT7623: Highspeed DMA, audio support
- Qualcomm IPQ8074 PCIe support, MSM8996 UFS support
- Renesas: Watchdog and PMU support across many platforms

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.

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"

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:

The Exynos5440 (quad-core A15 with GMAC, PCIe, SATA) was targeting
server platforms but it did not make it to the market really. There are
no development boards with it and probably there are no real products
neither. The development for Exynos5440 ended in 2013 and since then
the platform is in maintenance mode.
Remove all Device Tree sources for Exynos5440, as first step of removal
of the platform to simplify the code and drivers.

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
- i.MX6SLL SoCs

The main addition this time around is the new ARM "SCMI" framework,
which is the latest in a series of standards coming from ARM to do power
management in a platform independent way. This has been through many
review cycles, and it relies on a rather interesting way of using the
mailbox subsystem, but in the end I agreed that Sudeep's version was
the best we could do after all.
Other changes include:
- the ARM CCN driver is moved out of drivers/bus into drivers/perf,
which makes more sense. Similarly, the performance monitoring
portion of the CCI driver are moved the same way and cleaned up
a little more.
- a series of updates to the SCPI framework

This release brings up a new platform based on the old ARM9 core: the
Nuvoton NPCM is used as a baseboard management controller, competing
with the better known ASpeed AST2xx series.
Another important change is the addition of ARMv7-A based chips
in mach-stm32. The older parts in this platform are ARMv7-M based
microcontrollers, now they are expanding to general-purpose workloads.
The other changes are the usual defconfig updates to enable additional
drivers, lesser bugfixes. The largest updates as often are the ongoing
OMAP cleanups, but we also have a number of changes for the older
PXA and davinci platforms this time.
For the Renesas shmobile/r-car platform, some new infrastructure
is needed to make the watchdog work correctly.
Supporting Multiprocessing on Allwinner A80 required a significant
amount of new code, but is not doing anything unexpected.

Pull ARM SoC platform updates from Arnd Bergmann:
"This release brings up a new platform based on the old ARM9 core: the
Nuvoton NPCM is used as a baseboard management controller, competing
with the better known ASpeed AST2xx series.
Another important change is the addition of ARMv7-A based chips in
mach-stm32. The older parts in this platform are ARMv7-M based
microcontrollers, now they are expanding to general-purpose workloads.
The other changes are the usual defconfig updates to enable additional
drivers, lesser bugfixes. The largest updates as often are the ongoing
OMAP cleanups, but we also have a number of changes for the older PXA

This is the usual set of changes for device trees, with over 700
non-merged changesets. There is an ongoing set of dtc warning fixes and
the usual bugfixes, cleanups and added device support.
The most interesting bit as usual is support for new machines listed
below:
- The Allwinner H6 makes its debut with the Pine-H64 board, and we get
two new machines based on its older siblings: the H5 based OrangePi
Zero+ and the A64 based Teres-I Laptop from Olimex. On the 32-bit side,
we add The Olimex som204 based on Allwinner A20, and the Banana Pi M2
Zero development board (based on H2).
- NVIDIA adds support for Tegra194 aka "Xavier", plus their p2972
development board and p2888 CPU module.
- The Nuvoton npcm750 is a BMC that was newly added, for now we only
support running on the evaluation board.
- STmicroelectronics stm32 gains support for the stm32mp157c and two
evaluation boards.
- The Toradex Colibri board family grows a few members based on the
i.MX6ULL variant.
- The Advantec DMS-BA16 is a Qseven module using the NXP i.MX6
family of chips.
- The Phytec phyBOARD Mira is a family of industrial boards based on
i.MX6. For now, four models get added.
- TI am335x based PDU-001 is an industrial embedded machine used for
traffic monitoring
- The Aspeed platform now supports running on the BMC on the Qualcomm
Centriq 2400 server
- Samsung Exynos4 based Galaxy S3 is a family of mobile phones Qualcomm
msm8974 based Galaxy S5 is a rather different phone made by the same
company.
- The Xilinx Zynq and ZynqMP platforms now gained a lot of dts file
for the various boards made by Xilinx themselves, as well as the
Digilent Zybo Z7.
- The ARM Versatile family now supports the "IB2" interface board.
- The Renesas H2 based "Stout" and the H3 based Salvator-X are more
evaluation boards named after a kind of beer, as most of them are.
The r8a77980 (V3H) based "Condor" apparently doesn't follow that
tradition. ;-)
- ROC-RK3328-CC is a simple developement board from the Libre Computer
Project, based on the Rockchips RK3328 SoC
- Haiku is another development board plus Qseven module based on Rockchips
RK3368 and made by Theobroma Systems.

The low-pin-count (LPC) interface of Hip06/Hip07 accesses I/O port space of
peripherals.
Implement the LPC host controller driver which performs the I/O operations
on the underlying hardware. We don't want to touch existing drivers such
as ipmi-bt, so this driver applies the indirect-IO introduced in the
previous patch after registering an indirect-IO node to the indirect-IO
devices list which will be searched by the I/O accessors to retrieve the
host-local I/O port.
The driver config is set as a bool instead of a tristate. The reason here
is that, by the very nature of the driver providing a logical PIO range, it
does not make sense to have this driver as a loadable module. Another more
specific reason is that the Huawei D03 board which includes Hip06 SoC
requires the LPC bus for UART console, so should be built in.

Instead of having an early init function check the machine compatible
and installing multi-cluster SMP support for the A80 if it matches,
use a new cpu enable-method string. This makes the platform support
future proof in case anyone manages to add PSCI support.
The original init code for the SMP support is changed into the
.prepare_cpus callback in the smp_operations structure. Instead of
panicing when resources are missing like on some platforms, our code
merely guards against engaging SMP or CPU hotplug and returns an error.

ARM System Control and Management Interface(SCMI)[1] is more flexible and
easily extensible than any of the existing interfaces.
Few existing as well as future ARM platforms provide micro-controllers
to abstract various power and other system management tasks which have
similar interfaces, both in terms of the functions that are provided by
them, and in terms of how requests are communicated to them.
There are quite a few protocols like ARM SCPI, TI SCI, QCOM RPM, Nvidia Tegra
BPMP, and so on already. This specification is to standardize and avoid any
further fragmentation in the design of such interface by various vendors.
The current SCMI driver implementation is very basic and initial support.
It lacks support for notifications, asynchronous/delayed response, perf/power
statistics region and sensor register region.
Mailbox is the only form of transport supported currently in the driver.
SCMI supports interrupt based mailbox communication, where, on completion
of the processing of a message, the caller receives an interrupt as well as
polling for completion.
SCMI is designed to minimize the dependency on the mailbox/transport
hardware. So in terms of SCMI, each channel in the mailbox includes
memory area, doorbell and completion interrupt.
However the doorbell and completion interrupt is highly mailbox dependent
which was bit of controversial as part of SCMI/mailbox discussions.
Arnd and me discussed about the few aspects of SCMI and the mailbox framework:
1. Use of mailbox framework for doorbell type mailbox controller:
- Such hardware may not require any data to be sent to signal the remote
about the presence of a message. The channel will have in-built
information on how to trigger the signal to the remote.
There are few mailbox controller drivers which are purely doorbell based.
e.g.QCOM IPC, STM, Tegra, ACPI PCC,..etc
2. Supporting other mailbox controller:
- SCMI just needs a mechanism to signal the remote firmware. Such
controller may need fixed message to be sent to trigger a doorbell.
In such case we may need to get that data from DT and pass the same
to the controller. It's not covered in the current DT binding, but
can be extended as optional property in future.
However handling notifications may be interesting on such mailbox, but
again there is no way to interpret what the data field(remote message)
means, it could be a bit mask or a number or don't-care.
Arnd mentioned that he doesn't like the way the mailbox binding deals
with doorbell-type hardware, but we do have quite a few precedent drivers
already and changing the binding to add a data field would not make it any
better, but could cause other problems. So he is happy with the status quo
of SCMI implementation.

The arm-ccn driver is purely a perf driver for the CCN PMU, not a bus
driver in the sense of the other residents of drivers/bus/, so let's
move it to the appropriate place for SoC PMU drivers. Not to mention
moving the documentation accordingly as well.

This patch adds devicetree binding for System Control and Management
Interface (SCMI) Message Protocol used between the Application Cores(AP)
and the System Control Processor(SCP). The MHU peripheral provides a
mechanism for inter-processor communication between SCP's M3 processor
and AP.
SCP offers control and management of the core/cluster power states,
various power domain DVFS including the core/cluster, certain system
clocks configuration, thermal sensors and many others.
SCMI protocol is developed as better replacement to the existing SCPI
which is not flexible and easily extensible.

The Renesas Salvator-X development board can be equipped with an R-Car
H3, M3-W, or M3-N SiP, which are pin-compatible.
Document board part number and compatible values for the version with
R-Car M3-N.
The board part number was extracted from a big patch by Takeshi Kihara
in the BSP.
