This patch series introduces few fixes and performance optimizations
for the Qualcomm UFS host controller driver to improve performance
and to align with Qualcomm UFS hardware programming sequence.

The series addresses below issues:
1. Hardware programming sequence alignment for UFS controller v6.2
2. Performance tuning for sequential read workloads.

Changes from V1:
1. Dropped ufs: ufs-qcom: Add UFS ESI CPU affinity support from V1.
   I'll work and take it in separately in different series.
2. Addressed Konrad's comment to change version check from "only v6.2"
   to "starting with v6.2".
3. Addressed Konrad's comment to fix comment wording ("HS/LS" instead
    of "HS-LSS"):

Nitin Rawat (2):
  ufs: ufs-qcom: Restore HS/LS link startup mode for Qualcomm UFS
    controller v6.2+
  ufs: ufs-qcom: Fix sequential read variance
