Subject: [PATCH v6 3/5] clk: rockchip: save width in struct clk_fractional_divider
Date: Tue, 22 Sep 2015 18:54:10 +0300	[thread overview]
Message-ID: <1442937252-50281-4-git-send-email-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <1442937252-50281-1-git-send-email-andriy.shevchenko@linux.intel.com>

The ->mwidth and ->nwidth fields will be used by clk-fractional-divider when it
will be switched to rational base approximation algorithm.
