    BUS_DRIVER_PRESENT:
        description: >
            This indicated that hw/bus package is present in build.
            Do not override this settings.
        value: 1
    BUS_DEFAULT_LOCK_TIMEOUT_MS:
        description: >
            Default timeout for locking the bus. This can be overriden per-node.
        value: 1000
    BUS_DEFAULT_TRANSACTION_TIMEOUT_MS:
        description: >
            Default timeout for transaction on bus. This is used for simple
            transaction APIs (i.e. without timeout set explicitly)
        value: 50
    BUS_PM:
        description: >
            Enable extra power management capabilities for bus driver. This
            allows for some automatic management of bus device state instead of
            implementing this manually.
        value: 0

    BUS_STATS:
        description: >
            Enable statistics for bus devices. By default only global per-device
            statistics are enabled. Use BUS_STATS_PER_NODE to enable statistics
            for each node also.
        value: 0
    BUS_STATS_PER_NODE:
        description: >
            Enable per-node statistics for each bus node.
        value: 0
        restrictions: BUS_STATS

    BUS_DEBUG_OS_DEV:
        description: >
            Enable additional debugging for os_dev objects.
            Each os_dev object created by bus driver will be poisoned with
            magic value which is then checked on each operation to ensure
            proper objects are passed to APIs.
        value: 0
