Pull clk updates from Stephen Boyd:
"We have two changes to the core framework this time around.
The first being a large change that introduces runtime PM support to
the clk framework. Now we properly call runtime PM operations on the
device providing a clk when the clk is in use. This helps on SoCs
where the clks provided by a device need something to be powered on
before using the clks, like power domains or regulators. It also helps
power those things down when clks aren't in use.
The other core change is a devm API addition for clk providers so we
can get rid of a bunch of clk driver remove functions that are just
doing of_clk_del_provider().
Outside of the core, we have the usual addition of clk drivers and
smattering of non-critical fixes to existing drivers. The biggest diff
is support for Mediatek MT2712 and MT7622 SoCs, but those patches
really just add a bunch of data.
By the way, we're trying something new here where we build the tree up
with topic branches. We plan to work this into our workflow so that we
don't step on each other's toes, and so the fixes branch can be merged
on an as-needed basis.
Summary:
Core:
- runtime PM support for clk providers
- devm API for of_clk_add_hw_provider()
New Drivers:
- Mediatek MT2712 and MT7622
- Renesas R-Car V3M SoC
Updates:
- runtime PM support for Samsung exynos5433/exynos4412 providers
- removal of clkdev aliases on Samsung SoCs
- convert clk-gpio to use gpio descriptors
- various driver cleanups to match kernel coding style
- Amlogic Video Processing Unit VPU and VAPB clks
- sigma-delta modulation for Allwinner audio PLLs
- Allwinner A83t Display clks
- support for the second display unit clock on Renesas RZ/G1E
- suspend/resume support for Renesas R-Car Gen3 CPG/MSSR
- new clock ids for Rockchip rk3188 and rk3368 SoCs
- various 'const' markings on clk_ops structures
- RPM clk support on Qualcomm MSM8996/MSM8660 SoCs"

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.

>From Rockchips fractional divider description:
3.1.9 Fractional divider usage
To get specific frequency, clocks of I2S, SPDIF, UARTcan be generated by
fractional divider. Generally you must set that denominator is 20 times
larger than numerator to generate precise clock frequency. So the
fractional divider applies only to generate low frequency clock like
I2S, UART.
Therefore add a special approximation function that handles this
special requirement.

git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into clk-next
Pull rockchip clk driver updates from Heiko Stuebner:
General rockchip clock changes for 4.12. Contains some new clock-ids
as well as fixups of the clock-ids on rk3368 timers, which were unused
and completely wrong (more and differently named timers).
Also there is one new clock on rk3328 using the muxgrf type, a fix for
pll enablement which should wait for the pll to lock before continuing,
some more critical clocks and the rename of the rk1108 to rv1108, as the
soc seems to have been using a preliminary name before its actual release.
The plan is to have the driver changes (pinctrl, clk) go through the
respective maintainer trees and once everything landed in mainline do
the rename of the devicetree files. With the dts-include change in the
clock rename, we also keep everything compiling and thus bisectability.

The PMU Cortex M0 on rk3399 is intended to be used for things like
DDRFreq transitions, suspend/resume, and other things that are the
purview of ARM Trusted Firmware and not the kernel. As such, the
kernel shouldn't be messing with the clocks. Add CLK_IGNORE_UNUSED to
these clocks.
Without this change, the following was observed on a Chromebook with a
rk3399 (using not-yet-upstream ARM Trusted Firmware code and
not-yet-upstream kernel code based on kernel-4.4):
1. We init the clock framework.
2. We start up "DDRFreq", which causes ATF to occasionally fire up the
M0 for transitions. Each time ATF fires up the M0 it will turn on
these clocks and each time it is done it will turn them off.
3. We finally get to the the part of the kernel that calls
clk_disable_unused() and we disables the clocks.
You can see the race above. Basically everything is fine as long as
ARM Trusted Firmware isn't starting up the M0 at exactly the same time
that the kernel is disabling unused clocks. ...but if the race
happens then we go boom.

Rockchip socs often have some tiny number of muxes not controlled from
the core clock controller but through bits set in the general register
files. Add a clock-type that can control these as well, so that we
don't need to work around them being absent.

Pull rockchip clk driver updates from Heiko Stuebner:
A new clock controller for the rk1108 soc (single-core Cortex-A7+DSP),
a fix making sure the cpuclk rate is actually valid, before trying to
set it and a copy-paste fix for the rk3399's testclk.
