Subject: [PATCH 3/3] drm/exynos/fimd: signal frame done interrupt at front porch
Date: Tue, 28 Feb 2017 13:03:03 +0100 [thread overview]
Message-ID: <1488283383-4335-3-git-send-email-a.hajda@samsung.com> (raw)
In-Reply-To: <1488283383-4335-1-git-send-email-a.hajda@samsung.com>
VBLANK interrupt should be signalled as soon as scanout ends, front porch
is the best moment.
