This patchset adds 2 forms of interrupt aggregation support to the
driver:
- Interrupt converge: Interrupts from all completion queues can be
		      reported through completion queue #0 interrupt only.
- Interrupt coalesce: Ability to set timeout period at which we report
		      completions on that queue (as an interrupt).
		      The HW report completion interrupt as either
		      happens:
		      - configurable threshold of completions occur
		      - a timeout, so we don't pend indefinitely until
			the threshold is reached

There is also 2 minor patches to fix some register setting and also
rearrange some code for proper condition checking.

Xiang Chen (5):
  scsi: hisi_sas: Create separate host attributes per HBA
  scsi: hisi_sas: Add support for interrupt converge for v3 hw
  scsi: hisi_sas: Add support for interrupt coalescing for v3 hw
  scsi: hisi_sas: Relocate some codes to avoid an unused check
  scsi: hisi_sas: change the time of SAS SSP connection

Applied to 4.21/scsi-queue. Thank you!
