[PATCH v3 00/32] HiSilicon SAS driver

From: John Garry
Date: Mon Nov 09 2015 - 11:21:35 EST

This is the driver patchset for the HiSilicon SAS driver. The driver
is a platform driver.

The driver will support multiple revisions of HW. Currently only "v1"
HW is supported.

The driver uses libsas framework within the SCSI framework.

The v1 HW supports SSP and SMP, but not STP/SATA.

Differences to v2:
- update device tree bindings
- remove while loops when evaluating hba struct
- remove _lo and _hi DMA struct fields
- revised spinlock usage
- fix error handling for when CMPLT_HDR_ERR_RCRD_XFRD set
- general coding style and cosmetic fixes

Differences to v1:
- re-arch driver into main module and hw-specific driver module
- allocate hisi_hba in scsi_host_alloc
- use of_irq_count get irq count - depends on [1]
- use syscon to handle ctrl reg access
- get SAS address from device tree
- do not set cmd_per_lun to 1
- remove remove controller id
- use static wq in phy struct
- process control phy in caller context
- fix port->port_attached issue for rmmod
