Subject: [RFC PATCH 3/5] cpufreq: cpu0: Use clk_round_rate_nearest()
Date: Wed, 14 May 2014 15:30:53 -0700 [thread overview]
Message-ID: <1400106655-22465-4-git-send-email-soren.brinkmann@xilinx.com> (raw)
In-Reply-To: <1400106655-22465-1-git-send-email-soren.brinkmann@xilinx.com>
Round clock frequencies to the nearest possible frequency. As opposed to
the nearest that does not exceed the requested one.
