+description: |+
+ Common access controllers properties
+
+ Access controllers are in charge of stating which of the hardware blocks under
+ their responsibility (their domain) can be accesssed by which compartment. A
+ compartment can be a cluster of CPUs (or coprocessors), a range of addresses
+ or a group of hardware blocks. An access controller's domain is the set of
+ resources covered by the access controller.
+
+ This device tree binding can be used to bind devices to their access
+ controller provided by access-controllers property. In this case, the device
+ is a consumer and the access controller is the provider.
+
+ An access controller can be represented by any node in the device tree and
+ can provide one or more configuration parameters, needed to control parameters
+ of the consumer device. A consumer node can refer to the provider by phandle
+ and a set of phandle arguments, specified by '#access-controller-cells'
+ property in the access controller node.
+
+ Access controllers are typically used to set/read the permissions of a
+ hardware block and grant access to it. Any of which depends on the access
+ controller. The capabilities of each access controller are defined by the
+ binding of the access controller device.
+
+ Each node can be a consumer for the several access controllers.

+ Number of cells in an access-controllers specifier;
+ Can be any value as specified by device tree binding documentation
+ of a particular provider. The node is an access controller.

+ access-controller-names:
+ $ref: /schemas/types.yaml#/definitions/string-array
+ description:
+ A list of access-controllers names, sorted in the same order as
+ access-controllers entries. Consumer drivers will use
+ access-controller-names to match with existing access-controllers entries.
