Subject: [PATCH] dt-bindings: hwlock: Convert to dtschema
From: BiscuitBobby <simeddon@...il.com>
Convert the generic hwspinlock bindings to DT schema.
---
This is my first time converting bindings to dt schema, please let me
know if I have overlooked anything.

-Generic hwlock bindings
-=======================
-
-Generic bindings that are common to all the hwlock platform specific driver
-implementations.
-
-Please also look through the individual platform specific hwlock binding
-documentations for identifying any additional properties specific to that
-platform.
-
-hwlock providers:
-=================
-
-Required properties:
-- #hwlock-cells: Specifies the number of cells needed to represent a
- specific lock.
-
-hwlock users:
-=============
-
-Consumers that require specific hwlock(s) should specify them using the
-property "hwlocks", and an optional "hwlock-names" property.
-
-Required properties:
-- hwlocks: List of phandle to a hwlock provider node and an
- associated hwlock args specifier as indicated by
- #hwlock-cells. The list can have just a single hwlock
- or multiple hwlocks, with each hwlock represented by
- a phandle and a corresponding args specifier.
-
-Optional properties:
-- hwlock-names: List of hwlock name strings defined in the same order
- as the hwlocks, with one name per hwlock. Consumers can
- use the hwlock-names to match and get a specific hwlock.
-
-
-1. Example of a node using a single specific hwlock:
-
-The following example has a node requesting a hwlock in the bank defined by
-the node hwlock1. hwlock1 is a hwlock provider with an argument specifier
-of length 1.
-
- node {
- ...
- hwlocks = <&hwlock1 2>;
- ...
- };
-
-2. Example of a node using multiple specific hwlocks:
-
-The following example has a node requesting two hwlocks, a hwlock within
-the hwlock device node 'hwlock1' with #hwlock-cells value of 1, and another
-hwlock within the hwlock device node 'hwlock2' with #hwlock-cells value of 2.
-
- node {
- ...
- hwlocks = <&hwlock1 2>, <&hwlock2 0 3>;
- ...
- };
