Subject: [PATCH v2 0/8] clk: qcom: gcc: Update the SDCC RCGs to use
 shared_floor_ops

This series updates the clock ops to clk_rcg2_shared_floor_ops
for the SDCC RCGs on SM8450, SM8750, SM4450, SDX75, Milos,
X1E80100, QDU1000 and GLYMUR chipsets.

This change is required to ensure RCG is safely parked during
disable and new parent configuration is programmed in hardware
only when new parent is enabled, to avoid cases where RCG
configuration fails to update and overclocking issues.

Changes in v2:
- Added patches 6,7,8 to use shared_floor_ops for SDCC RCGs on X1E80100,
  QDU1000 and GLYMUR chipsets also.
- picked the R-By tags received on v1.
- Link to v1: https://lore.kernel.org/r/20251126-sdcc_shared_floor_ops-v1-0-9038430dfed4@oss.qualcomm.com
