Access to GICR_WAKER is restricted on msm8996 SoC in Hypervisor.
There are many devices out there with this restriction in place
and there has been no update to this firmware since last few years,
making those devices totally unusable for upstream development.
IIDR register value conflicts with other SoCs, using compatible seems
to be the only way to apply quirks required for msm8996 based SoCs.
Without this quirk many qcom SoCs (atleast 3 that I know) are
unable to boot mainline.

In the past, there have been words on various lists that if LDO3 is
disabled in u-boot, but enabled in the DTS, the axp209 driver would
fail to continue/hang. Several enable/disable patches have been
issues to devicetree's in both the kernel and u-boot to address
this issue.
What really happened however, was that the AXP209 shuts down without
a notice and without setting an interrupt. This is caused when LDO3
gets overloaded, for example with large capacitors on the LDO3 output.
Normally, we would expect that AXP209 would source 200 mA as per
datasheet and set and trigger an interrupt when being overloaded.
For some reason however, this does not happen.
As a work-around, implement software-based 'regulator-soft-start'
property for AXP209 LDO3 regulator, which is used to first bring up
the LDO3 to the lowest possible voltage and then enable the LDO.
After that, we can set the requested voltage as usual.
Combining this setting with the regulator-ramp-delay allows LDO3 to
come up slowly and staggered, potentially reducing overall inrush current.

The AXP209 supports ramping up voltages on several regulators such as
DCDC2 and LDO3, therefore we can use the standard 'regulator-ramp-delay'
property for those 2 regulators.
Note that the voltage ramp only works when the regulator is already
enabled. E.g. when going from say 0.7 V to 3.6 V.
When turning on the regulator, no voltage ramp is performed in hardware.
What this means, is that if the bootloader brings up the voltage at 0.7 V,
the ramp delay property is properly applied. If however, the bootloader
leaves the power off, no ramp delay is applied when the power is
enabled by the regulator framework.

Convert the i2c-gpio binding to DT schema format using json-schema. This
serves as an example of how to include other schema (i2c-controller.yaml
in this case).
Signed-off-by: Rob Herring <robh@kernel.org>
Add a how-to doc on writing DT schema documentation. This gives a
description of each section and details on how to validate the DT schema
file. The DT schema are written using json-schema vocabulary in a YAML
encoded document. Using jsonschema gives us access to existing tooling.
A YAML encoding gives us something easy to edit. The example is
annotated to help explain what each section does.
This example is just the tip of the iceberg, but is it the part most
developers writing bindings will interact with. Backing all this up
are meta-schema (to validate the binding schemas), some DT core schema,
YAML encoded DT output with dtc, and a small number of python scripts to
run validation.

This adds the build infrastructure for checking DT binding schema
documents and validating dts files using the binding schema.
Check DT binding schema documents:
make dt_binding_check
Build dts files and check using DT binding schema:
make dtbs_check
Optionally, DT_SCHEMA_FILES can be passed in with a schema file(s) to
use for validation. This makes it easier to find and fix errors
generated by a specific schema.
Currently, the validation targets are separate from a normal build to
avoid a hard dependency on the external DT schema project and because
there are lots of warnings generated.

Add two new metrics for CPU idle states, "above" and "below", to count
the number of times the given state had been asked for (or entered
from the kernel's perspective), but the observed idle duration turned
out to be too short or too long for it (respectively).
These metrics help to estimate the quality of the CPU idle governor
in use.
