    Subject[PATCH v4 0/8] scsi: ufs: support LU Dedicated buffer mode for WriteBooster
    Date
    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"

    scsi: ufs: introduce fixup_dev_quirks vops

    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
