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.

Convert ROHM bd71837 and bd71847 PMIC binding text docs to yaml. Split
the binding document to two separate documents (own documents for BD71837
and BD71847) as they have different amount of regulators. This way we can
better enforce the node name check for regulators. ROHM is also providing
BD71850 - which is almost identical to BD71847 - main difference is some
initial regulator states. The BD71850 can be driven by same driver and it
has same buck/LDO setup as BD71847 - add it to BD71847 binding document and
introduce compatible for it.

MP8867 is an I2C-controlled adjustable voltage regulator made by
Monolithic Power Systems. The difference between MP8867 and MP8869
are:
1.If V_BOOT, the vref of MP8869 is fixed at 600mv while vref of MP8867
is determined by the I2C control.
2.For MP8867, when setting voltage, if the steps is within 5, we need
to manually set the GO_BIT to 0.

There is voltage coupling between three regulators on Tegra20 boards and
between two on Tegra30. The voltage coupling is a SoC-level feature and
thus it is mandatory and common for all of the Tegra boards.

Regulator '*-supply' properties are always a single phandle, so
'maxItems: 1' or a $ref is not necessary. All that's needed is either
'true' or an optional 'description'. Following this clean-up, the
meta-schema will enforce this pattern.
There's one case in tree with 'innolux,n156bge-l21' having 2 phandles.
This appears to be a mistake or abuse of simple-panel as it's 2 different
voltage rails connected to 'power-supply'.

This adds the documentation to the compatible regulator-fixed-clock.
This binding is a special binding of regulator-fixed and adds the
ability to add a clock to regulator-fixed, so the regulator can be
enabled and disabled with that clock. If the special compatible
regulator-fixed-clock is used it is mandatory to supply a clock.

During reset the VMMC regulator doesn't reach 0V and only drops to
1.8V, furthermore the pulse width is under 200us whereas the SD
specification expect 1ms.
For this 2 reasons being able to no reset at all the VMMC during warm
reset and keep the current voltage is a good workaround. The TWL6030
allows this but needs to be aware of it and this configuration should
also be shared with the bootloader.
This is the purpose of this new property: ti,retain-on-reset
