+Subject: [PATCH 104/182] clk: qcom: Return highest rate when round_rate()
+ exceeds plan
+
+Some drivers may want to call clk_set_rate() with a very large
+number to force the clock to go as fast as it possibly can
+without having to know the range between the highest rate and
+second highest rate. Add support for this by defaulting to the
+highest rate in the frequency table if we can't find a frequency
+greater than what is requested.
