A recent review highlighted that the json-schema meta-schema allows any
combination of if/then/else schema keywords even though if, then or else
by themselves makes little sense. With an added meta-schema to only
allow valid combinations, there's a handful of schemas found which need
fixing in a variety of ways. Incorrect indentation is the most common
issue.

Tegra SoCs have extra on-chip RAM that can be used for inter-processor
communication. Tegra186 and later make use of it to establish a two-way
channel between the CCPLEX and BPMP. Add missing compatible strings for
Tegra186 and Tegra194 as well as a new compatible string for Tegra234.

Pull ARM SoC driver updates from Arnd Bergmann:
"These are all the driver updates for SoC specific drivers. There are a
couple of subsystems with individual maintainers picking up their
patches here:
- The reset controller subsystem add support for a few new SoC
variants to existing drivers, along with other minor improvements
- The OP-TEE subsystem gets a driver for the ARM FF-A transport
- The memory controller subsystem has improvements for Tegra,
Mediatek, Renesas, Freescale and Broadcom specific drivers.
- The tegra cpuidle driver changes get merged through this tree this
time. There are only minor changes, but they depend on other tegra
driver updates here.
- The ep93xx platform finally moves to using the drivers/clk/
subsystem, moving the code out of arch/arm in the process. This
depends on a small sound driver change that is included here as
well.
- There are some minor updates for Qualcomm and Tegra specific
firmware drivers.
The other driver updates are mainly for drivers/soc, which contains a
mixture of vendor specific drivers that don't really fit elsewhere:
- Mediatek drivers gain more support for MT8192, with new support for
hw-mutex and mmsys routing, plus support for reset lines in the
mmsys driver.
- Qualcomm gains a new "sleep stats" driver, and support for the
"Generic Packet Router" in the APR driver.
- There is a new user interface for routing the UARTS on ASpeed BMCs,
something that apparently nobody else has needed so far.
- More drivers can now be built as loadable modules, in particular
for Broadcom and Samsung platforms.
- Lots of improvements to the TI sysc driver for better
suspend/resume support"
Finally, there are lots of minor cleanups and new device IDs for
amlogic, renesas, tegra, qualcomm, mediateka, samsung, imx,
layerscape, allwinner, broadcom, and omap"

The Qualcomm SMEM binding always depended on a reference to a SRAM node
of compatible "qcom,rpm-msg-ram", document this as part of the SRAM
binding.
The SRAM is consumed as a whole and not split up using subnodes, so
properties related to this are not required.

Commit a90b15e0ad72 ("Documentation: bindings: decouple juno specific
details from generic binding") moved the juno specific bindings into
separate file. Though there was no need for juno specific binding, it
has been used unfortunately for whatever stupid reason I added it for.
Let us move the same to the generic sram.yaml schema and remove the
old text format binding.

DT properties which can have multiple entries need to specify what the
entries are and define how many entries there can be. In the case of
only a single entry, just 'maxItems: 1' is sufficient.
Add the missing entry constraints. These were found with a modified
meta-schema. Unfortunately, there are a few cases where the size
constraints are not defined such as common bindings, so the meta-schema
can't be part of the normal checks.

Current dts files with 'rockchip-pmu-sram' compatible nodes
are now verified with sram.yaml, although the original
text document still exists. Merge rockchip-pmu-sram.txt
with sram.yaml by adding it as description with an example.
Make #address-cells, #size-cells and ranges optional

Even though the generic mmio-sram binding has a list of the sections
compatible allowed, most device trees have more specific compatibles
attached to those generic ones.
This creates warnings at the moment, and we don't really want to cripple
the generic binding with all the vendor specific combinations that would
prove to be hard to maintain.
Let's allow additional compatibles for the sections, and then we can have
the vendor-specific bindings to reduce the scope of what's allowed exactly.

The generic SRAM binding currently only allows for child nodes of an SRAM
to be called sram too. However, these are also called sections in a number
of device tree, which seems a bit more accurate.
Let's change the name pattern to allow both.
