Subject: [Intel-gfx] [PATCH v3 15/25] drm/dp_mst: Factor out a helper to check the atomic state of a topology manager
Date: Thu, 14 Sep 2023 22:26:49 +0300	[thread overview]
Message-ID: <20230914192659.757475-16-imre.deak@intel.com> (raw)
In-Reply-To: <20230914192659.757475-1-imre.deak@intel.com>

Factor out a helper to check the atomic state for one MST topology
manager, returning the MST port where the BW limit check has failed.
This will be used in a follow-up patch by the i915 driver to improve the
BW sharing between MST streams.
