[PATCH 0/5] clk: qcom: gcc: Update the SDCC RCGs to use shared_floor_ops

[Jagadeesh Kona]

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

[PATCH 5/5] clk: qcom: gcc-milos: Update the SDCC RCGs to use shared_floor_ops

[Jagadeesh Kona]

Use shared_floor_ops for the SDCC RCGs to avoid any overclocking
issues in SDCC usecases.

Fixes: 88174d5d9422 ("clk: qcom: Add Global Clock controller (GCC) driver for Milos")
