Subject: [RFC PATCH 05/13] drm/msm/disp/dpu1: Add support for DSC in pingpong block
Date: Fri, 21 May 2021 18:19:36 +0530 [thread overview]
Message-ID: <20210521124946.3617862-8-vkoul@kernel.org> (raw)
In-Reply-To: <20210521124946.3617862-1-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>
