Subject: [PATCH v7 04/18] drm/i915/display: Add VRR DC balance registers
Date: Tue, 24 Jun 2025 13:19:34 +0530	[thread overview]
Message-ID: <20250624074948.671761-5-mitulkumar.ajitkumar.golani@intel.com> (raw)
In-Reply-To: <20250624074948.671761-1-mitulkumar.ajitkumar.golani@intel.com>

Add VRR register offsets and bits to access DC Balance configuration.

--v2:
- Separate register definitions. (Ankit)
- Remove usage of dev_priv. (Jani, Nikula)

--v3:
- Convert register address offset, from capital to small. (Ankit)
- Move mask bits near to register offsets. (Ankit)

--v4:
- Use _MMIO_TRANS wherever possible. (Jani)
