Subject: [RFC PATCH 08/13] drm/msm/disp/dpu1: Add DSC support in hw_ctl
Date: Fri, 21 May 2021 18:19:40 +0530	[thread overview]
Message-ID: <20210521124946.3617862-12-vkoul@kernel.org> (raw)
In-Reply-To: <20210521124946.3617862-1-vkoul@kernel.org>

Later gens of hardware have DSC bits moved to hw_ctl, so configure these
bits so that DSC would work there as well
