Subject: [PATCH v2 7/8] clk: qcom: gcc-qdu1000: Update the SDCC RCGs to use
 shared_floor_ops

Use shared_floor_ops for the SDCC RCGs so the RCG is safely parked
during disable and the new parent configuration is programmed in
hardware only when the new parent is enabled, avoiding cases where
the RCG configuration fails to update.
