Subject: [PATCH 05/17] drm/msm/dpu: rip out master planes support
Date: Thu, 24 Jun 2021 17:57:21 +0300	[thread overview]
Message-ID: <20210624145733.2561992-6-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20210624145733.2561992-1-dmitry.baryshkov@linaro.org>

Master/virtual planes were used for multirect support. In preparation to
reworking DPU planes, drop support for master planes (which was not used
anyway).
