[v4,0/8] Use UFS device indicated maximum LU number

Message

Bean Huo Jan. 20, 2020, 1:08 p.m. UTC

This series of patches is to simplify UFS driver initialization flow
and add a new parameter max_lu_supported used to specify how many LUs
supported by the UFS device.
This series of patches being tested on my two platforms, Qualcomm SOC
based and Hisilicon SOC based platforms.                                                                                                                                                                   
v1-v2:
    1. Split ufshcd_probe_hba() based on its called flow
    2. Delete two unnecessary functions
    3. Add a fixup patch

v2-v3:
    1. Combine patches 7/9 and 8/9 of v2 to patch 7/8 of v3
    2. Change patches 1/8 and 5/8 subject
    3. Change the name of two functions in patch 7/8

v3-v4:
    1. Change patch 4/8 subject
    2. Change new added function name from ufshcd_init_params() to
       ufshcd_device_params_init()
    3. Change new added function name from ufshcd_init_device_geo_params()
       to ufshcd_device_geo_params_init()
    4. Fix two compilation errors in patch 2/8:
       1) Missed an operator "&" in function ufs_mtk_apply_dev_quirks()
          when getting address of the dev_info.
       2) Incorrectly changed hba->dev_quirks to dev_info->dev_quirks in
          function ufs_qcom_apply_dev_quirks().
