- * 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.
