Subject: [PATCH 07/17] drm/amd/display: Only allow dig mapping to pwrseq in new asic
Date: Wed, 14 Feb 2024 11:38:38 -0700 [thread overview]
Message-ID: <20240214184006.1356137-8-Rodrigo.Siqueira@amd.com> (raw)
In-Reply-To: <20240214184006.1356137-1-Rodrigo.Siqueira@amd.com>
From: Lewis Huang <lewis.huang@amd.com>
[Why]
The old asic only have 1 pwrseq hw.
We don't need to map the diginst to pwrseq inst in old asic.
[How]
1. Only mapping dig to pwrseq for new asic.
2. Move mapping function into dcn specific panel control component
