   4 Subject: [PATCH 4/9] clk: qcom: krait-cc: register REAL qsb fixed clock
   5
   6 With some tools it was discovered the real frequency of the qsb fixed
   7 clock. While not 100% correct it's still better than using 1 as a dummy
   8 frequency.
   9 Correctly register the qsb fixed clock with the frequency of 225 MHz
  10 instead of 1.
