Linus Torvalds ca4e7c5120 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
  - i.MX6SLL SoCs
 
 Removed Drivers:
  - ST-Ericsson AB8540/9540
 
 Updates:
  - Mediatek MT2701 and MT7622 audsys support and MT2712 updates
  - 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

Linus Torvalds 38c23685b2 ARM: SoC driver updates for 4.17
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
 
 - support for the Mediatek mt7623a SoC in drivers/soc
 
 - support for additional NVIDIA Tegra hardware in drivers/soc
 
 - a new reset driver for Socionext Uniphier
 
 - lesser bug fixes in drivers/soc, drivers/tee, drivers/memory, and
   drivers/firmware and drivers/reset across platforms

Greg Kroah-Hartman b24413180f License cleanup: add SPDX GPL-2.0 license identifier to files with no license
Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.

By default all files without license information are under the default
license of the kernel, which is GPL version 2.

Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier.  The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.

This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.

How this work was done:

Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
 - file had no licensing information it it.
 - file was a */uapi/* one with no licensing information in it,
 - file was a */uapi/* one with existing licensing information,

Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.

The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne.  Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.

The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed.  Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.

Criteria used to select files for SPDX license identifier tagging was:
 - Files considered eligible had to be source code files.
 - Make and config files were included as candidates if they contained >5
   lines of source
 - File already had some variant of a license header in it (even if <5
   lines).

All documentation files were explicitly excluded.

The following heuristics were used to determine which SPDX license
identifiers to apply.

 - when both scanners couldn't find any license traces, file was
   considered to have no license information in it, and the top level
   COPYING file license applied.

   For non */uapi/* files that summary was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0                                              11139

   and resulted in the first patch in this series.

   If that file was a */uapi/* path one, it was "GPL-2.0 WITH
   Linux-syscall-note" otherwise it was "GPL-2.0".  Results of that was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0 WITH Linux-syscall-note                        930

   and resulted in the second patch in this series.

 - if a file had some form of licensing information in it, and was one
   of the */uapi/* ones, it was denoted with the Linux-syscall-note if
   any GPL family license was found in the file or had no licensing in
   it (per prior point).  Results summary:

   SPDX license identifier                            # files
   ---------------------------------------------------|------
   GPL-2.0 WITH Linux-syscall-note                       270
   GPL-2.0+ WITH Linux-syscall-note                      169
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause)    21
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause)    17
   LGPL-2.1+ WITH Linux-syscall-note                      15
   GPL-1.0+ WITH Linux-syscall-note                       14
   ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause)    5
   LGPL-2.0+ WITH Linux-syscall-note                       4
   LGPL-2.1 WITH Linux-syscall-note                        3
   ((GPL-2.0 WITH Linux-syscall-note) OR MIT)              3
   ((GPL-2.0 WITH Linux-syscall-note) AND MIT)             1

   and that resulted in the third patch in this series.

 - when the two scanners agreed on the detected license(s), that became
   the concluded license(s).

 - when there was disagreement between the two scanners (one detected a
   license but the other didn't, or they both detected different
   licenses) a manual inspection of the file occurred.

 - In most cases a manual inspection of the information in the file
   resulted in a clear resolution of the license that should apply (and
   which scanner probably needed to revisit its heuristics).

 - When it was not immediately clear, the license identifier was
   confirmed with lawyers working with the Linux Foundation.

 - If there was any question as to the appropriate license identifier,
   the file was flagged for further research and to be revisited later
   in time.

In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.

Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights.  The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.

Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.

In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.

Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
 - a full scancode scan run, collecting the matched texts, detected
   license ids and scores
 - reviewing anything where there was a license detected (about 500+
   files) to ensure that the applied SPDX license was correct
 - reviewing anything where there was no detection but the patch license
   was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
   SPDX license was correct

This produced a worksheet with 20 files needing minor correction.  This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.

These .csv files were then reviewed by Greg.  Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected.  This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.)  Finally Greg ran the script using the .csv files to
generate the patches.

Linus Torvalds dddd564dbb This time we've got one core change to introduce a bulk clk_get API,
some new clk drivers and updates for old ones. The diff is pretty
 spread out across a handful of different SoC clk drivers for Broadcom, TI,
 Qualcomm, Renesas, Rockchip, Samsung, and Allwinner, mostly due to the
 introduction of new drivers.
 
 Core:
  - New clk bulk get APIs
  - Clk divider APIs gained the ability to consider a different parent than
    the current one
 
 New Drivers:
  - Renesas r8a779{0,1,2,4} CPG/MSSR
  - TI Keystone SCI firmware controlled clks and OMAP4 clkctrl
  - Qualcomm IPQ8074 SoCs
  - Cortina Systems Gemini (SL3516/CS3516)
  - Rockchip rk3128 SoCs

 "This time we've got one core change to introduce a bulk clk_get API,
  some new clk drivers and updates for old ones. The diff is pretty
  spread out across a handful of different SoC clk drivers for Broadcom,
  TI, Qualcomm, Renesas, Rockchip, Samsung, and Allwinner, mostly due to
  the introduction of new drivers.

  Core:
   - New clk bulk get APIs
   - Clk divider APIs gained the ability to consider a different parent

Chen-Yu Tsai 05359be117 clk: sunxi-ng: Add driver for A83T CCU
The A83T clock control unit is a hybrid of some new style clock designs
from the A80, and old style layout from the other Allwinner SoCs.

Like the A80, the SoC does not have a low speed 32.768 kHz oscillator.
Unlike the A80, there is no clock input either. The only low speed clock
available is the internal oscillator which runs at around 16 MHz,
divided by 512, yielding a low speed clock around 31.250 kHz.

Also, the MMC2 module clock supports switching to a "new timing" mode.
This mode divides the clock output by half, and disables the CCU based
clock delays. The MMC controller must be configure to the same mode,
and then use its internal clock delays.

This driver does not support runtime switching of the timing modes.
Instead, the new timing mode is enforced at probe time. Consumers can
check which mode is active by trying to get the current phase delay
of the MMC2 phase clocks, which will return -ENOTSUPP if the new
timing mode is active.

With the A80 SoC, Allwinner grouped and moved some subsystem specific
clock controls to a separate address space, and possibly separate

One such subsystem is the display engine. The main clock control unit
now only has 1 set of bus gate, dram gate, module clock, and reset
control for the entire display subsystem. These feed into a secondary
clock control unit, which has controls for each individual module
of the display pipeline. This block is not documented in the user
manual. Allwinner's kernel was used as the reference.

Linus Torvalds 991688bfc6 ARM: SoC driver updates for v4.10
Driver updates for ARM SoCs, including a couple of newly added drivers:
 
 - A new driver for the power management controller on TI Keystone
 - Support for the prerelease "SCPI" firmware protocol that ended up
   being shipped by Amlogic in their GXBB SoC.
 - A soc_device can now be matched using a glob from inside the
   kernel, when another driver wants to know the specific chip
   it is running on and cannot find out from DT, firmware or hardware.
 - Renesas SoCs now support identification through the soc_device
   interface, both in user space and kernel.
 - Renesas r8a7743 and r8a7745 gain support for their system controller
 - A new checking module for the ARM "PSCI" (not to be confused
   with "SCPI" mentioned above) firmware interface.
 - A new driver for the Tegra GMI memory interface
 - Support for the Tegra firmware interfaces with their
   power management controllers
 
 As usual, the updates for the reset controller framework are merged
 here, as they tend to touch multiple SoCs as well, including a new
 driver for the Oxford (now Broadcom) OX820 chip and the Tegra
 bpmp interface.
 
 The existing drivers for Atmel, Qualcomm, NVIDIA, TI Davinci, and
 Rockchips SoCs see some further updates.
 
 Conflicts:
 - ARCH_RENESAS now selects SOC_BUS, but no longer needs GPIOLIB
 - drivers/soc/renesas/Makefile: multiple files got added, keep
   all in logical sorting

Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC driver updates from Arnd Bergmann:
 "Driver updates for ARM SoCs, including a couple of newly added
  drivers:

   - A new driver for the power management controller on TI Keystone

   - Support for the prerelease "SCPI" firmware protocol that ended up
     being shipped by Amlogic in their GXBB SoC.

   - A soc_device can now be matched using a glob from inside the
     kernel, when another driver wants to know the specific chip it is
     running on and cannot find out from DT, firmware or hardware.

   - Renesas SoCs now support identification through the soc_device
     interface, both in user space and kernel.

   - Renesas r8a7743 and r8a7745 gain support for their system
     controller

   - A new checking module for the ARM "PSCI" (not to be confused with
     "SCPI" mentioned above) firmware interface.

   - A new driver for the Tegra GMI memory interface

   - Support for the Tegra firmware interfaces with their power
     management controllers

  As usual, the updates for the reset controller framework are merged
  here, as they tend to touch multiple SoCs as well, including a new
  driver for the Oxford (now Broadcom) OX820 chip and the Tegra bpmp
  interface.

  The existing drivers for Atmel, Qualcomm, NVIDIA, TI Davinci, and
  Rockchips SoCs see some further updates"

Olof Johansson e40719dd01 firmware: Add Tegra IVC and BPMP support
IVC is an inter-processor communication protocol that uses shared memory
 to exchange data between processors. The BPMP driver makes use of this
 to communicate with the Boot and Power Management Processor (BPMP) and
 uses an additional hardware synchronization primitive from the HSP block
 to signal availability of new data (doorbell).
 
 Firmware running on the BPMP implements a number of services such as the
 control of clocks and resets within the system, or the ability to ungate
 or gate power partitions.

Joseph Lo d55865608f dt-bindings: firmware: Add bindings for Tegra BPMP
The Boot and Power Management Processor (BPMP) is a co-processor found
in Tegra SoCs. It is designed to handle the early stages of the boot
process as well as to offload power management tasks (such as clocks,
resets, powergates, ...).

The binding document defines the resources that are used by the BPMP
firmware, which implements the interprocessor communication (IPC)
between the CPU and the BPMP.

This commit introduces the clocks found in the Allwinner A33 CCU.

Since this SoC is very similar to the A23, and we share a significant share
of the DTSI, the clock IDs that are going to be used will also be shared
with the A23, hence the name of the various header files.
