Subject: [RFC PATCH 3/6] drm/msm/dpu1: Wire up DSC mask for active CTL configuration
Date:   Wed, 14 Dec 2022 00:22:04 +0100
Message-Id: <20221213232207.113607-4-marijn.suijten@somainline.org>
In-Reply-To: <20221213232207.113607-1-marijn.suijten@somainline.org>
References: <20221213232207.113607-1-marijn.suijten@somainline.org>

Active CTLs have to configure what DSC block(s) have to be enabled, and
what DSC block(s) have to be flushed; this value was initialized to zero
resulting in the necessary register writes to never happen (or would
write zero otherwise).  This seems to have gotten lost in the DSC v4->v5
series while refactoring how the combination with merge_3d was handled.

Fixes: 58dca9810749 ("drm/msm/disp/dpu1: Add support for DSC in encoder")
