Subject: [PATCH v1 0/7] i2c: busses: Introduce and use HZ_PER_GHZ
Date: Mon, 12 Jan 2026 14:46:08 +0100 [thread overview]
Message-ID: <20260112134900.4142954-1-andriy.shevchenko@linux.intel.com> (raw)
A few drivers for I²C host controllers use HZ_PER_GHZ in numeric form.
This is less readable and prone to subtle mistakes. Instead, introduce
a well defined constant and use it in the drivers. No functional change
implied except one case where 64-bit division replaced with 32-bit one.
Andy Shevchenko (7):
units: Add HZ_PER_GHZ
i2c: mlxbf: Use HZ_PER_GHZ constant instead of custom one
i2c: mt65xx: Use HZ_PER_GHZ constant instead of plain number
i2c: nomadik: Use HZ_PER_GHZ constant instead of plain number
i2c: rk3x: Use HZ_PER_GHZ constant instead of plain number
i2c: st: Use HZ_PER_GHZ constant instead of plain number
i2c: synquacer: Use HZ_PER_GHZ constant instead of plain number
