scsi: hisi_sas: add skeleton v3 hw driver
Add skeleton driver for v3 hw in hisi_sas_v3_hw.c File hisi_sas_v3_hw.c will serve 2 purposes: - probing and initialisation of the controller based on pci device - hw layer for v3-based controllers The controller design is quite similar to v2 hw in hip07. However key differences include: -All v2 hw bugs are fixed (hopefully), so workarounds are not required -support for device deregistration -some interrupt modifications -configurable max device support Signed-off-by: John Garry <john.garry@huawei.com> Signed-off-by: Xiang Chen <chenxiang66@hisilicon.com> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
