Message-Id: <1400281634-9313-4-git-send-email-sboyd@codeaurora.org> Date: Fri, 16 May 2014 16:07:10 -0700 From: Stephen Boyd <sboyd@...eaurora.org> To: Mike Turquette <mturquette@...aro.org> Cc: linux-kernel@...r.kernel.org, linux-arm-msm@...r.kernel.org, linux-arm-kernel@...ts.infradead.org Subject: [PATCH 3/7] 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.
