Subject: [PATCH v8 09/15] drm/msm/disp/dpu: use atomic enable/disable callbacks for encoder functions
Date:   Wed, 12 Oct 2022 17:32:33 +0530
Message-Id: <1665576159-3749-10-git-send-email-quic_vpolimer@quicinc.com>
In-Reply-To: <1665576159-3749-1-git-send-email-quic_vpolimer@quicinc.com>
References: <1665576159-3749-1-git-send-email-quic_vpolimer@quicinc.com>
Precedence: bulk

Use atomic variants for encoder callback functions such that
certain states like self-refresh can be accessed as part of
enable/disable sequence.
