4 Generic bindings that are common to all the hwlock platform specific driver
11 hwlock providers:
18 hwlock users:
22 property "hwlocks", and an optional "hwlock-names" property.
27 #hwlock-cells. The list can have just a single hwlock
32 - hwlock-names: List of hwlock name strings defined in the same order
34 use the hwlock-names to match and get a specific hwlock.
