Subject: [PATCH 03/11] drm/msm/disp/dpu1: Add support for DSC in pingpong block
Date: Thu, 15 Jul 2021 12:21:55 +0530 [thread overview]
Message-ID: <20210715065203.709914-4-vkoul@kernel.org> (raw)
In-Reply-To: <20210715065203.709914-1-vkoul@kernel.org>
In SDM845, DSC can be enabled by writing to pingpong block registers, so
add support for DSC in hw_pp
Signed-off-by: Vinod Koul <vkoul@kernel.org>
