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>; |
|
... |
|
};
