Subject: [PATCH v1 17/40] i2c: imx-lpi2c: Use generic definitions for bus frequencies
Date: Mon, 24 Feb 2020 17:15:07 +0200	[thread overview]
Message-ID: <20200224151530.31713-17-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20200224151530.31713-1-andriy.shevchenko@linux.intel.com>

Since we have generic definitions for bus frequencies, let's use them.
