Subject: [PATCH v1 7/7] i2c: synquacer: Use HZ_PER_GHZ constant instead of plain number
Date: Mon, 12 Jan 2026 14:46:15 +0100 [thread overview]
Message-ID: <20260112134900.4142954-8-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20260112134900.4142954-1-andriy.shevchenko@linux.intel.com>
Use defined constant to avoid the possible mistakes and to provide
an additional information on the units.
