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>; ... };
