Add YAML DT schema for the AMD AXI w1 host IP.
This hardware guarantees protocol timing for driving off-board devices
such as thermal sensors, proms, etc using the 1wire protocol. The IP
has a register to detect hardware version and so the binding does not
have an explicit version number.
Add MAINTAINERS entry for DT schema.

This adds a dedicated devicetree binding for the Maxim DS2482/DS2484
I2C to 1-W bridges, which can be extended later for further features
(e.g. sleep mode control GPIO). Since one wire is a bus, child nodes
needs to be allowed here.

As indicated in
link: https://lore.kernel.org/all/[email protected]/
DT schema files should not have 'Device Tree Binding' as part of there
title: line. Remove this in most .yaml files, so hopefully preventing
developers copying it into new .yaml files, and being asked to remove
it.

Drop another redundant maxItems that snuck into w1-gpio binding.
If a property has an 'items' list, then a 'minItems' or 'maxItems' with the
same size as the list is redundant and can be dropped. Note that is DT
schema specific behavior and not standard json-schema behavior. The tooling
will fixup the final schema adding any unspecified minItems/maxItems.

Bitbanged 1-Wire buses are supported by Linux thanks to their device
tree binding.
Now that we have the DT validation in place, let's convert the device
tree bindings for that driver over to a YAML schema.

Clean-up incorrect indentation, extra spaces, and missing EOF newline in
schema files. Most of the clean-ups are for list indentation which
should always be 2 spaces more than the preceding keyword.
Found with yamllint (now integrated into the checks).

This patch adds a generic w1 bindings document that describes how w1
slave deviceses are grouped under master nodes. It also augments the
existing w1-gpio.txt document a bit.

Pretty much any node can have a status property, so it doesn't need to
be in examples.
Converted with the following command and removed examples with SoC and
board specific splits:
git grep -l -E 'status.*=.*' Documentation/devicetree/ | xargs sed -i -E '/\sstatus.*=.*"(disabled|ok|okay)/d'

This patches makes following changes to omap_hdq driver
- Enable 1-wire mode.
- Implement w1_triplet callback to facilitate search rom
procedure and auto detection of 1-wire slaves.
- Proper enabling and disabling of interrupt.
- Cleanups (formatting and return value checks).
HDQ mode remains unchanged.

This driver has no 'compatible' string and so is not found when
using device-tree.
Add one with value to match
hdqw1w: 1w@480b2000 {
device in omap3.dtsi.
