Subject: [PATCH] drm/msm/dpu: fix smart dma support
Date: Tue, 11 May 2021 17:17:11 +0300 [thread overview]
Message-ID: <20210511141711.635820-1-dmitry.baryshkov@linaro.org> (raw)
Downstream driver uses dpu->caps->smart_dma_rev to update
sspp->cap->features with the bit corresponding to the supported SmartDMA
version. Upstream driver does not do this, resulting in SSPP subdriver
not enbaling setup_multirect callback. Make SSPP subdriver check global
smart_dma_rev to decide if setup_multirect should be enabled.
