 - A bunch more binding conversions to DT schema. Only 3K to go.

 - Add a minimum version check for schema tools

 - Treewide dropping of 'allOf' usage with schema references. Not needed
   in new json-schema spec.

c54030b191 dt-bindings: timer: Document allwinner,erratum-unknown1 property
This arch_timer property was added in commit c950ca8c35
("clocksource/drivers/arch_timer: Workaround for Allwinner A64 timer instability")
but I omitted the device tree binding documentation. Now
`make dtbs_check` prints the following warning for all A64 boards:

timer: 'allwinner,erratum-unknown1' does not match any of the regexes: 'pinctrl-[0-9]+'

Resolve this by documenting the erratum property.

3d21a46093 dt-bindings: Remove cases of 'allOf' containing a '$ref'
json-schema versions draft7 and earlier have a weird behavior in that
any keywords combined with a '$ref' are ignored (silently). The correct
form was to put a '$ref' under an 'allOf'. This behavior is now changed
in the 2019-09 json-schema spec and '$ref' can be mixed with other
keywords. The json-schema library doesn't yet support this, but the
tooling now does a fixup for this and either way works.

This has been a constant source of review comments, so let's change this
treewide so everyone copies the simpler syntax.

Scripted with ruamel.yaml with some manual fixups. Some minor whitespace
changes from the script.

7f464532b0 dt-bindings: Add missing 'additionalProperties: false'
Setting 'additionalProperties: false' is frequently omitted, but is
important in order to check that there aren't extra undocumented
properties in a binding.

Ideally, we'd just add this automatically and make this the default, but
there's some cases where it doesn't work. For example, if a common
schema is referenced, then properties in the common schema aren't part
of what's considered for 'additionalProperties'. Also, sometimes there
are bus specific properties such as 'spi-max-frequency' that go into
bus child nodes, but aren't defined in the child node's schema.

So let's stick with the json-schema defined default and add
'additionalProperties: false' where needed. This will be a continual
review comment and game of wack-a-mole.

Pull timekeeping and timer updates from Thomas Gleixner:
 "Core:

   - Consolidation of the vDSO build infrastructure to address the
     difficulties of cross-builds for ARM64 compat vDSO libraries by
     restricting the exposure of header content to the vDSO build.

     This is achieved by splitting out header content into separate
     headers. which contain only the minimaly required information which
     is necessary to build the vDSO. These new headers are included from
     the kernel headers and the vDSO specific files.

   - Enhancements to the generic vDSO library allowing more fine grained
     control over the compiled in code, further reducing architecture
     specific storage and preparing for adopting the generic library by
     PPC.

   - Cleanup and consolidation of the exit related code in posix CPU
     timers.

   - Small cleanups and enhancements here and there

  Drivers:

   - The obligatory new drivers: Ingenic JZ47xx and X1000 TCU support

   - Correct the clock rate of PIT64b global clock

   - setup_irq() cleanup

   - Preparation for PWM and suspend support for the TI DM timer

   - Expand the fttmr010 driver to support ast2600 systems

   - The usual small fixes, enhancements and cleanups all over the
     place"

c5c689d322 dt-bindings: timer: Use non-empty ranges in example
On many arm64 qcom device trees, running `make dtbs_check` yells:

  timer@17c20000: #size-cells:0:0: 1 was expected

It appears that someone was trying to assert the fact that sub-nodes
describing frames would never have a size that's more than 32-bits
big.  That does indeed appear to be true for all cases I could find.

Currently many arm64 qcom device tree files have a #address-cells and
about in commit bede7d2dc8 ("arm64: dts: qcom: sdm845: Increase
address and size cells for soc").  That means the only way we can
shrink them down is to use a non-empty ranges.

Since forever it has said in "writing-bindings.txt" to "DO use
non-empty 'ranges' to limit the size of child buses/devices".  I guess
we should start listening to it.

I believe (but am not certain) that this also means that we should use
"ranges" to simplify the "reg" of our sub devices by specifying an
offset.  Let's update the example in the bindings to make this
obvious.

 "Main MIPS changes:

   - boot_mem_map is removed, providing a nice cleanup made possible by

   - Some fixes to atomics, in general providing compiler barriers for
     smp_mb__{before,after}_atomic plus fixes specific to Loongson CPUs
     or MIPS32 systems using cmpxchg64().

   - Conversion to the new generic VDSO infrastructure courtesy of
     Vincenzo Frascino.

   - Removal of undefined behavior in set_io_port_base(), fixing the
     behavior of some MIPS kernel configurations when built with recent
     clang versions.

   - Initial MIPS32 huge page support, functional on at least Ingenic
     SoCs.

   - pte_special() is now supported for some configurations, allowing
     among other things generic fast GUP to be used.

   - Miscellaneous fixes & cleanups.

  And platform specific changes:

   - Major improvements to Ingenic SoC support from Paul Cercueil,
     mostly enabled by the inclusion of the new TCU (timer-counter unit)
     drivers he's spent a very patient year or so working on. Plus some
     fixes for X1000 SoCs from Zhou Yanjie.

   - Netgear R6200 v1 systems are now supported by the bcm47xx platform.

 "Timers and timekeeping updates:

   - A large overhaul of the posix CPU timer code which is a preparation
     for moving the CPU timer expiry out into task work so it can be
     properly accounted on the task/process.

     An update to the bogus permission checks will come later during the
     merge window as feedback was not complete before heading of for
     travel.

   - Switch the timerqueue code to use cached rbtrees and get rid of the
     homebrewn caching of the leftmost node.

   - Consolidate hrtimer_init() + hrtimer_init_sleeper() calls into a
     single function

   - Implement the separation of hrtimers to be forced to expire in hard
     interrupt context even when PREEMPT_RT is enabled and mark the
     affected timers accordingly.

   - Implement a mechanism for hrtimers and the timer wheel to protect
     RT against priority inversion and live lock issues when a (hr)timer
     which should be canceled is currently executing the callback.
     Instead of infinitely spinning, the task which tries to cancel the
     timer blocks on a per cpu base expiry lock which is held and
     released by the (hr)timer expiry code.

   - Enable the Hyper-V TSC page based sched_clock for Hyper-V guests
     resulting in faster access to timekeeping functions.

   - Updates to various clocksource/clockevent drivers and their device
     tree bindings.

   - The usual small improvements all over the place"

1be8c9fd2a dt-bindings: timer: renesas, cmt: Update R-Car Gen3 CMT1 usage
The R-Car Gen3 SoCs so far come with a total for 4 on-chip CMT devices:
 - CMT0
 - CMT1
 - CMT2
 - CMT3

CMT0 includes two rather basic 32-bit timer channels. The rest of the on-chip
CMT devices support 48-bit counters and have 8 channels each.

Based on the data sheet information "CMT2/3 are exactly same as CMT1"
it seems that CMT2 and CMT3 now use the CMT1 compat string in the DTSI.

Clarify this in the DT binding documentation by describing R-Car Gen3 and
RZ/G2 CMT1 as "48-bit CMT devices".

Document the on-chip CMT devices included in r8a7740 and sh73a0.

Included in this patch is DT binding documentation for 32-bit CMTs
CMT0, CMT2, CMT3 and CMT4. They all contain a single channel and are
quite similar however some minor differences still exist:
 - "Counter input clock" (clock input and on-device divider)
    One example is that RCLK 1/1 is supported by CMT2, CMT3 and CMT4.
 - "Wakeup request" (supported by CMT0 and CMT2)

Because of this one unique compat string per CMT device is selected.
