We've been accruing these for a couple of weeks, so the batch is a bit
bigger than usual.
Largest delta is due to a led-bl driver that is added -- there was
a miscommunication before the merge window and the driver didn't make it
in. Due to this, the platforms needing it regressed. At this point, it
seemed easier to add the new driver than unwind the changes.
Besides that, there are a handful of various fixes:
- AMD tee memory leak fix
- A handful of fixlets for i.MX SCU communication
- A few maintainers woke up and realized DEBUG_FS had been missing for
a while, so a few updates of that.
... and the usual collection of smaller fixes to various platforms.

The hierarchical topology with power-domain should be described through

Commit 1de243b076 ("media: dt-bindings: media: sun4i-csi: Add compatible
for CSI1 on A10/A20") introduced support for the CSI1 controller on A10 and
A20 that unlike CSI0 doesn't have an ISP and therefore only have two
clocks, the bus and module clocks.
The clocks and clock-names properties have thus been modified to allow
either two or tree clocks. However, the current list has the ISP clock at
the second position, which means the bindings expects a list of either
bus and isp, or bus, isp and mod. The initial intent of the patch was
obviously to have bus and mod in the former case.
Let's fix the binding so that it validates properly.

The example in the Tegra124 EMC device tree binding looks like an old

version from the current DTS files to fix the make dt_binding_check

Commit f5a98bfe7b ("dt-bindings: display: Convert Allwinner display
pipeline to schemas") introduced a YAML schema for the Allwinner TCON DT
binding, but the H6 TCON-TV compatible was mistakenly set to fallback on
the A83t's, while the initial documentation and the DT are using R40's.
Fix that.

The intel,rcu-gw binding example has an error:
Documentation/devicetree/bindings/reset/intel,rcu-gw.example.dt.yaml:
reset-controller@e0000000: intel,global-reset: [[16, 30]] is too short
The error isn't really correct as the problem is in how the data is
encoded and the schema is not fixed up by the tooling correctly.
However, array properties should describe the elements in the array, so
lets do that which fixes the error in the process.

"A pretty small batch for us, and apologies for it being a bit late, I
wanted to sneak Christophe's user_access_begin() series in.
Summary:
- Implement user_access_begin() and friends for our platforms that
support controlling kernel access to userspace.
- Enable CONFIG_VMAP_STACK on 32-bit Book3S and 8xx.
- Some tweaks to our pseries IOMMU code to allow SVMs ("secure"
virtual machines) to use the IOMMU.
- Add support for CLOCK_{REALTIME/MONOTONIC}_COARSE to the 32-bit
VDSO, and some other improvements.
- A series to use the PCI hotplug framework to control opencapi
card's so that they can be reset and re-read after flashing a new
FPGA image.
As well as other minor fixes and improvements as usual.

This makes the qcom,videocc bindings match the recent changes to the
dispcc and gpucc.
1. Switched to using "bi_tcxo" instead of "xo".
2. Adds a description for the XO clock. Not terribly important but
nice if it cleanly matches its cousins.
3. Updates the example to use the symbolic name for the RPMH clock and
also show that the real devices are currently using 2 address cells
/ size cells and fixes the spacing on the closing brace.
4. Split into 2 files. In this case they could probably share one
file, but let's be consistent.

The qcom,gpucc bindings had a few problems with them:
1. When things were converted to yaml the name of the "gpll0 main"
clock got changed from "gpll0" to "gpll0_main". Change it back for
msm8998.
2. Apparently there is a push not to use purist aliases for clocks but
instead to just use the internal Qualcomm names. For sdm845 and
sc7180 (where the drivers haven't already been changed) move in
this direction.
Things were also getting complicated harder to deal with by jamming
several SoCs into one file. Splitting simplifies things.

The qcom,dispcc bindings had a few problems with them:
1. They didn't specify all the clocks that dispcc is a client of.
Specifically on sc7180 there are two clocks from the DSI PHY and
two from the DP PHY. On sdm845 there are actually two DSI PHYs
(each of which has two clocks) and an extra clock from the gcc.
These all need to be specified.
2. The sdm845.dtsi has existed for quite some time without specifying
the clocks. The Linux driver was relying on global names to match
things up. While we should transition things, it should be noted
in the bindings.
3. The names used the bindings for "xo" and "gpll0" didn't match the
names that QC used for these clocks internally and this was causing
confusion / difficulty with their code generation tools. Switched
to the internal names to simplify everyone's lives. It's not quite
as clean in a purist sense but it should avoid headaches. This
officially changes the binding, but that seems OK in this case.
Also note that I updated the example.

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 code

I then picked this patch atop linux-next (next-20200129) and ran:
# Delete broken yaml:
rm Documentation/devicetree/bindings/pci/intel-gw-pcie.yaml
ARCH=arm64 make dt_binding_check | grep 'clock/qcom'
...and that didn't seem to indicate problems.
Arbitrary decisions made (yell if you want changed):
- Left all the older devices (where clocks / clock-names weren't
specified) in a single file.
- Didn't make clocks "required" for msm8996 but left them as listed.
This seems a little weird but it matches the old binding.
Misc cleanups as part of this patch:
- Fixed schema id to not have "bindings/" as per Rob [1].
- Listed include files as per Stephen.
- sm8150 was claimed to be same set of clocks as sc7180, but driver
and dts appear to say that "bi_tcxo_ao" doesn't exist. Fixed.
- In "apq8064", "#thermal-sensor-cells" was missing the "#".
- Got rid of "|" at the end of top description since spacing doesn't
matter.
- Changed indentation to consistently 2 spaces (it was 3 in some
places).
- Added period at the end of protected-clocks description.
- No space before ":".
- Updated sc7180/sm8150 example to use the 'qcom,rpmh.h' include.
- Updated sc7180/sm8150 example to use larger address/size cells as
per reality.
- Updated sc7180/sm8150 example to point to the sleep_clk rather than
<0>.
- Made it so that gcc-ipq8074 didn't require #power-domain-cells since
actual dts didn't have it and I got no hits from:
git grep _GDSC include/dt-bindings/clock/qcom,gcc-ipq8074.h
- Made it so that gcc-qcs404 didn't require #power-domain-cells since
actual dts didn't have it and I got no hits from:
git grep _GDSC include/dt-bindings/clock/qcom,gcc-qcs404.h
Noticed, but not done in this patch (volunteers needed):
- Add "aud_ref_clk" to sm8150 bindings / dts even though I found a
reference to it in "gcc-sm8150.c".
- Fix node name in actual ipq8074 to be "clock-controller" (it's gcc).
- Since the example doesn't need phandes to exist, in msm8998 could
just make up places providing some of the clocks currently bogused
out with <0>.
- On msm8998 clocks are listed as required but current dts doesn't
have them.

Having 'bindings' in here causes a warning when checking the schema.
Documentation/devicetree/bindings/clock/fsl,plldig.yaml:
$id: relative path/filename doesn't match actual path or filename
expected: http://devicetree.org/schemas/clock/fsl,plldig.yaml#
Remove it.
