2020-11-17scsi: ufs: ufs-hisi: Use device parameter initialization functionStanley Chu1-12/+1
Use common device parameter initialization function instead of initializing those parameters by vendor driver itself.

2020-02-13scsi: ufs: introduce common function to disable host TX LCCStanley Chu1-1/+1
Many vendors would like to disable host TX LCC during initialization flow. Introduce a common function for all users to make drivers easier to read and maintained. This patch does not change any functionality.

Without CONFIG_OF, the of_match_node() helper does not evaluate its argument, and the compiler warns about the unused variable: drivers/scsi/ufs/ufs-hisi.c: In function 'ufs_hisi_probe': drivers/scsi/ufs/ufs-hisi.c:673:17: error: unused variable 'dev' [-Werror=unused-variable] Rework this code to pass the data directly, and while we're at it, correctly handle the const pointers.

2019-02-20scsi: ufs: Add HI3670 SoC UFS driver supportManivannan Sadhasivam1-22/+105
Add HI3670 SoC UFS driver support by extending the common ufs-hisi driver. One major difference between HI3660 ad HI3670 SoCs interms of UFS is the PHY. HI3670 has a 10nm variant PHY and hence this parameter is used to distinguish the configuration.

2018-11-09scsi: ufs: Fix hynix ufs bug with quirk on hi36xx SoCWei Li1-0/+9
Hynix ufs has deviations on hi36xx platform which will result in ufs bursts transfer failures. To fix the problem, the Hynix device must set the register VS_DebugSaveConfigTime to 0x10, which will set time reference for SaveConfigTime is 250 ns. The time reference for SaveConfigTime is 40 ns by default. This patch is necessary to boot on HiKey960 boards that use Hynix UFS chips (H28U62301AMR model: hB8aL1).
