From 9d011f3b71f635ff8e664e7e32bb764918cb1e8e Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Fri, 16 May 2014 16:07:10 -0700 Subject: 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.
