- * struct vexpress_config_bridge_info - description of the platform
- * configuration infrastructure bridge.
- *
- * @name:       Bridge name
- *
- * @func_get:   Obtains pointer to a configuration function for a given
- *              device or a Device Tree node, to be used with @func_put
- *              and @func_exec. The node pointer should take precedence
- *              over device pointer when both are passed.
- *
- * @func_put:   Tells the bridge that the function will not be used any
- *              more, so all allocated resources can be released.
- *
- * @func_exec:  Executes a configuration function read or write operation.
- *              The offset selects a 32 bit word of the value accessed.
- *              Must return VEXPRESS_CONFIG_STATUS_DONE when operation
- *              is finished immediately, VEXPRESS_CONFIG_STATUS_WAIT when
- *              will be completed in some time or negative value in case
- *              of error.
