Subject: [PATCH v3 03/27] drm/msm/dpu: move SSPP debugfs creation to dpu_kms.c
Date: Fri,  3 Feb 2023 20:21:08 +0200	[thread overview]
Message-ID: <20230203182132.1307834-4-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20230203182132.1307834-1-dmitry.baryshkov@linaro.org>

As SSPP blocks are now visible through dpu_kms->rm.sspp_blocks, move
SSPP debugfs creation from dpu_plane to dpu_kms. We are going to break
the 1:1 correspondence between planes and SSPPs, so it makes no sense
anymore to create SSPP debugfs entries in dpu_plane.c
