Subject: [PATCH v1 2/3] clk: tegra: Add more rates to Tegra30 PLLX frequency table
Date: Thu, 30 Aug 2018 22:20:44 +0300	[thread overview]
Message-ID: <20180830192045.11017-3-digetx@gmail.com> (raw)
In-Reply-To: <20180830192045.11017-1-digetx@gmail.com>

Add more predefined rates to the PLLX table, allowing to lower the rate
down to 312MHz. This gives more variations of frequency selection to the
CPUFREQ driver.
