Subject: [PATCH v3 6/7] clk: tegra: switch to clk_div_mask()
Date: Tue, 31 Mar 2015 20:22:26 +0300	[thread overview]
Message-ID: <1427822547-163289-7-git-send-email-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <1427822547-163289-1-git-send-email-andriy.shevchenko@linux.intel.com>

Convert the code to use clk_div_mask() helper instead of div_mask() macro.
