Subject: [PATCH 2/3] drm/tilcdc: Enable EOF interrupts for v1 LCDC
Date: Tue, 23 Aug 2016 12:57:00 +0000 [thread overview]
Message-ID: <20160823125701.25700-3-kbeldan@baylibre.com> (raw)
In-Reply-To: <20160823125701.25700-1-kbeldan@baylibre.com>
This got accidentally dropped in the fixed commit and is required for
the driver to properly work on the rev1 IP, such as found on the LCDK.
Fixes: 2b2080d7e9ae ("drm/tilcdc: Get rid of complex ping-pong mechanism")
Signed-off-by: Karl Beldan <kbeldan@baylibre.com>
