Subject: [PATCH v4 5/6] i2c: algo: Use generic definitions for bus frequencies
Date: Fri, 20 Mar 2020 21:12:48 +0200 [thread overview]
Message-ID: <20200320191249.28835-5-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20200320191249.28835-1-andriy.shevchenko@linux.intel.com>
Since we have generic definitions for bus frequencies, let's use them.
