This series enables HS-G5 support on SM8550. This series is rebased on below changes from Mani - https://patchwork.kernel.org/project/linux-scsi/patch/20230908145329.154024-1-manivannan.sadhasivam@xxxxxxxxxx/ https://patchwork.kernel.org/project/linux-scsi/patch/20230908145329.154024-2-manivannan.sadhasivam@xxxxxxxxxx/ This series is tested on below HW combinations - SM8550 MTP + UFS4.0 SM8550 QRD + UFS3.1 SM8450 MTP + UFS3.1 (for regression test) 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.
