[PATCH v8 5/7] scsi: hisi_sas: Add libsas SATA sysfs attributes group

Igor Pylypiv
2024-03-07T21:44:35Z

The added sysfs attributes group enables the configuration of NCQ Priority
feature for HBAs that rely on libsas to manage SATA devices.

Omitted hisi_sas_v1_hw.c because v1 HW doesn't support SATA.
