   4 Subject: [PATCH 1/4] clk: qcom: clk-krait: fix wrong div2 functions
   5
   6 Currently div2 value is applied to the wrong bits. This is caused by a
   7 bug in the code where the shift is done only for lpl, for anything
   8 else the mask is not shifted to the correct bits.
   9
  10 Fix this by correctly shift if lpl is not supported.
