Subject: [PATCH v7 03/18] drm/i915/display: Add pipe dmc registers and bits for DC Balance
Date: Tue, 24 Jun 2025 13:19:33 +0530	[thread overview]
Message-ID: <20250624074948.671761-4-mitulkumar.ajitkumar.golani@intel.com> (raw)
In-Reply-To: <20250624074948.671761-1-mitulkumar.ajitkumar.golani@intel.com>

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Add pipe dmc registers and  access bits for DC Balance params
configuration and enablement.

--v2:
- Separate register definitions for transcoder and
pipe dmc. (Ankit)
- Use MMIO pipe macros instead of transcoder ones. (Ankit)
- Remove dev_priv use. (Jani, Nikula)

--v3:
- Add all register address, from capital alphabet to small. (Ankit)
- Add EVT CTL registers.
- Add co-author tag.
- Add event flag for Triggering DC Balance.
