Subject: [PATCH v1 1/7] units: Add HZ_PER_GHZ
Date: Mon, 12 Jan 2026 14:46:09 +0100 [thread overview]
Message-ID: <20260112134900.4142954-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20260112134900.4142954-1-andriy.shevchenko@linux.intel.com>
The is going to be a new user of the HZ_PER_GHZ definition besides
possibly existing ones. Add that one to the header.
While at it, split Hz and kHz groups of the multipliers for better
maintenance and readability.
