Pull clk updates from Stephen Boyd:
"There are a few changes to the core framework this time around, in
addition to the normal collection of driver updates to support new
SoCs, fix incorrect data, and convert various drivers to clk_hw based
APIs.In the core, we allow clk_ops::init() to return an error code now so
that we can fail clk registration if the callback does something like
fail to allocate memory. We also add a new "terminate" clk_op so that
things done in clk_ops::init() can be undone, e.g. free memory. We
also spit out a warning now when critical clks fail to enable and we
support changing clk rates and enable/disable state through debugfs
when developers compile the kernel themselves.On the driver front, we get support for what seems like a lot of
Qualcomm and NXP SoCs given that those vendors dominate the diffstat.
There are a couple new drivers for Xilinx and Amlogic SoCs too. The
updates are all small things like fixing the way glitch free muxes
switch parents, avoiding div-by-zero problems, or fixing data like
parent names. See the updates section below for more details.Finally, the "basic" clk types have been converted to support
specifying parents with clk_hw pointers. This work includes an
overhaul of the fixed-rate clk type to be more modern by using clk_hw
APIs.Core:
- Let clk_ops::init() return an error code
- Add a clk_ops::terminate() callback to undo clk_ops::init()
- Warn about critical clks that fail to enable or prepare
- Support dangerous debugfs actions on clks with dead codeNew Drivers:
- Support for Xilinx Versal platform clks

This flag was historically used to indicate that a clk is a "basic" type
of clk like a mux, divider, gate, etc. This never turned out to be very
useful though because it was hard to cleanly split "basic" clks from
other clks in a system. This one flag was a way for type introspection
and it just didn't scale. If anything, it was used by the TI clk driver
to indicate that a clk_hw wasn't contained in the SoC specific clk
structure. We can get rid of this define now that TI is finding those
clks a different way.Cc: Tero Kristo

These are in fact two clocks, they shouldn't be exposed as one. One is
required for accessing LCD controller registers (peripheral clock), while
other (AXI clock) can be optionally used as a pixel clock source for the
panel.LCDC can alternatively use different clocks than the Display 1 AXI clock
for generating the pixel clock: the second AXI clock (fixed in this
commit too), the HDMI PLL, or the AXI bus clock.They should really be controlled independently.

It seems that the kernel has no business managing this clock: once the SP
clock is disabled, it's not sufficient to just enable in order to bring the
SP core back up. Just let the firmware keep it enabled and don't expose it
to drivers.This reverts commit fc27c2394d96fd19854b7e2d3f0e60df0d86fc90.

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:

- runtime PM support for clk providers
- devm API for of_clk_add_hw_provider()New Drivers:
- Mediatek MT2712 and MT7622

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

The mmp clock drivers currently hardcode the physical addresses for
the clock registers. This is generally a bad idea, and it also gets in
the way of multiplatform builds, which make the platform header files
inaccessible to device drivers.To work around the header file problem, this patch changes the calling
convention so the three mmp clock drivers get initialized with the base
addresses as arguments from the platform code.It would still be useful to have a larger rework of the clock drivers,
with DT integration to let the clocks actually be probed automatically,
and the base addresses passed as DT properties. I am unsure if anyone
is still interested in the mmp platform, so it is possible that this
won't happen.Signed-off-by: Arnd Bergmann

Some determine_rate implementations are not returning an error
when they failed to adapt the rate according to the rate request.
Fix them so that they return an error instead of silently
returning 0.Signed-off-by: Boris Brezillon

Clock rates are stored in an unsigned long field, but ->determine_rate()
(which returns a rounded rate from a requested one) returns a long
value (errors are reported using negative error codes), which can lead
to long overflow if the clock rate exceed 2Ghz.Change ->determine_rate() prototype to return 0 or an error code, and pass
a pointer to a clk_rate_request structure containing the expected target
rate and the rate constraints imposed by clk users.The clk_rate_request structure might be extended in the future to contain
other kind of constraints like the rounding policy, the maximum clock
inaccuracy or other things that are not yet supported by the CCF
(power consumption constraints ?).Signed-off-by: Boris Brezillon

Clock provider drivers generally shouldn't include clk.h because
it's the consumer API. Remove the include here because this is a
provider driver. The clkdev.h include isn't used either, so drop
it and add in slab.h to keep things compiling.Cc: Chao Xie
