This series is rebased on below changes from Mani - https://patchwork.kernel.org/project/linux-scsi/patch/20230908145329.154024-1-manivannan.sadhasivam@linaro.org/ https://patchwork.kernel.org/project/linux-scsi/patch/20230908145329.154024-2-manivannan.sadhasivam@linaro.org/ This series is tested on below HW combinations - SM8550 MTP + UFS4.0 SM8550 QRD + UFS3.1 SM8450 MTP + UFS3.1 (for regression test) SM8350 MTP + UFS3.1 (for regression test) Note that during reboot test on above platforms, I occasinally hit PA (PHY) error during the 2nd init, this is not related with this series. A fix for this is mentioned in below patchwork - https://patchwork.kernel.org/project/linux-scsi/patch/1698145815-17396-1-git-send-email-quic_ziqichen@quicinc.com/ Also note that on platforms, which have two sets of UFS PHY settings are provided (say G4 and no-G4, G5 and no-G5). The two sets of PHY settings are basically programming different values to different registers, mixing the two sets and/or overwriting one set with another set is definitely not blessed by UFS PHY designers. For SM8550, this series will make sure we honor the rule. However, for old targets Mani and I will fix them in another series in future. v4 -> v5: Removed two useless debug prints in patch #9 v3 -> v4: 1. Used .tbls_hs_overlay array instead of adding more tables with different names like .tbls_hs_g5 v2 -> v3: 1. Addressed comments from Andrew, Mani and Bart in patch #1 2. Added patch #2 as per request from Andrew and Mani 3. Added patch #4 to fix a common issue on old targets, it is not necessary for this series, but put in this series only because it would be easier to maintain and no need to rebase 4. Addressed comments from Dmitry and Mani in patches to phy-qcom-qmp-ufs.c v1 -> v2: 1. Removed 2 changes which were exposing power info in sysfs 2. Removed 1 change which was moving data structs to phy-qcom-qmp-ufs.h 3. Added one new change (the 1st one) to clean up usage of ufs_dev_params based on comments from Mani 4. Adjusted the logic of UFS device version detection according to comments from Mani: 4.1 For HW version < 0x5, go through dual init 4.2 For HW version >= 0x5 a. If UFS device version is populated, one init is required b. If UFS device version is not populated, go through dual init Bao D.
