* @in_debug: whether the device is in a state where the profiling/tracing infrastructure
* can be used. This indication is needed because in some ASICs we need to do
* specific operations to enable that infrastructure.
- * @power9_64bit_dma_enable: true to enable 64-bit DMA mask support. Relevant
- * only to POWER9 machines.
* @cdev_sysfs_created: were char devices and sysfs nodes created.
* @stop_on_err: true if engines should stop on error.
* @supports_sync_stream: is sync stream supported.
