   4 Subject: [PATCH 10/14] clk: qcom: gcc-ipq806x: add additional freq for sdc
   5  table
   6
   7 Add additional freq supported for the sdc table. The ops are changed to
   8 the floor_ops to handle a freq request of 52kHz where we need to provide
   9 a freq of 51.2kHz instead for stability reason.
