Subject: [PATCH v2 04/11] drm/i915/vrr: Move CMRR hw registers to fix refresh rate path
Date: Tue, 16 Jun 2026 20:12:25 +0530	[thread overview]
Message-ID: <20260616144233.832276-5-mitulkumar.ajitkumar.golani@intel.com> (raw)
In-Reply-To: <20260616144233.832276-1-mitulkumar.ajitkumar.golani@intel.com>

Move CMRR register writes to fix refresh rate register write path
to consolidate with fix refresh rate implementation.
