Hi, This patchset adds LU dedicated buffer mode support for WriteBooster. In the meanwhile, enable WriteBooster capability on MediaTek UFS platforms. v3 -> v4: - Introduce "fixup_dev_quirks" vops to allow vendors to fix and modify device quirks, and provide an initial vendor-specific device quirk table on MediaTek UFS platforms - Avoid relying on common device quirk table for pre-3.1 UFS device with non-standard WriteBooster support (Can Guo) - Fix comments for ufshcd_wb_probe() (Can Guo) - Make ufshcd_wb_get_flag_index() inline and fix ufshcd_is_wb_flags() (Avri Altman) v2 -> v3: - Introduce a device quirk to support WriteBooster in pre-3.1 UFS devices (Avri Altman) - Fix WriteBooster related sysfs nodes. Now all WriteBooster related sysfs nodes are specifically mapped to the LUN with WriteBooster enabled in LU Dedicated buffer mode (Avri Altman) v1 -> v2: - Change the definition name of WriteBooster buffer mode to correspond to specification (Bean Huo) - Add patch #5: "scsi: ufs: cleanup WriteBooster feature" Stanley Chu (8): scsi: ufs: enable WriteBooster on some pre-3.1 UFS devices scsi: ufs: introduce fixup_dev_quirks vops scsi: ufs: export ufs_fixup_device_setup() function scsi: ufs-mediatek: add fixup_dev_quirks vops scsi: ufs: add "index" in parameter list of ufshcd_query_flag() scsi: ufs: add LU Dedicated buffer mode support for WriteBooster scsi: ufs-mediatek: enable WriteBooster capability scsi: ufs: cleanup WriteBooster feature drivers/scsi/ufs/ufs-mediatek.c | 25 ++++- drivers/scsi/ufs/ufs-sysfs.c | 11 ++- drivers/scsi/ufs/ufs.h | 7 ++ drivers/scsi/ufs/ufs_quirks.h | 7 ++ drivers/scsi/ufs/ufshcd.c | 157 ++++++++++++++++++++------------ drivers/scsi/ufs/ufshcd.h | 20 +++- 6 files changed, 165 insertions(+), 62 deletions(-) -- 2.18.0
