* @handle: Handle to the allocation, written by the kernel (only valid in
* case of %FW_CDEV_IOC_ALLOCATE_ISO_RESOURCE ioctls)
*
* The %FW_CDEV_IOC_ALLOCATE_ISO_RESOURCE ioctl initiates allocation of an
* isochronous channel and/or of isochronous bandwidth at the isochronous
* resource manager (IRM). Only one of the channels specified in @channels is
* allocated. An %FW_CDEV_EVENT_ISO_RESOURCE_ALLOCATED is sent after
* communication with the IRM, indicating success or failure in the event data.
* The kernel will automatically reallocate the resources after bus resets.
* Should a reallocation fail, an %FW_CDEV_EVENT_ISO_RESOURCE_DEALLOCATED event
* will be sent. The kernel will also automatically deallocate the resources
* when the file descriptor is closed.
*
* The %FW_CDEV_IOC_DEALLOCATE_ISO_RESOURCE ioctl can be used to initiate
* deallocation of resources which were allocated as described above.
* An %FW_CDEV_EVENT_ISO_RESOURCE_DEALLOCATED event concludes this operation.
*
* The %FW_CDEV_IOC_ALLOCATE_ISO_RESOURCE_ONCE ioctl is a variant of allocation
* without automatic re- or deallocation.
* An %FW_CDEV_EVENT_ISO_RESOURCE_ALLOCATED event concludes this operation,
* indicating success or failure in its data.
*
* The %FW_CDEV_IOC_DEALLOCATE_ISO_RESOURCE_ONCE ioctl works like
* %FW_CDEV_IOC_ALLOCATE_ISO_RESOURCE_ONCE except that resources are freed
* instead of allocated.
* An %FW_CDEV_EVENT_ISO_RESOURCE_DEALLOCATED event concludes this operation.
*
* To summarize, %FW_CDEV_IOC_DEALLOCATE_ISO_RESOURCE allocates iso resources
* for the lifetime of the fd or handle.
* In contrast, %FW_CDEV_IOC_ALLOCATE_ISO_RESOURCE_ONCE allocates iso resources
* for the duration of a bus generation.
*
* @channels is a host-endian bitfield with the least significant bit
* representing channel 0 and the most significant bit representing channel 63:
* 1ULL << c for each channel c that is a candidate for (de)allocation.
*
* @bandwidth is expressed in bandwidth allocation units, i.e. the time to send
* one quadlet of data (payload or header data) at speed S1600.
