Subject: [PATCH] ARM: at91/dt: ov2640: add hsync/vsync-active property
Date: Fri, 18 Sep 2015 19:28:22 +0800 [thread overview]
Message-ID: <1442575702-22315-1-git-send-email-josh.wu@atmel.com> (raw)
On at91sam9x5ek/at91sam9m10g45ek/sama5d3xek boards, we use the parallel
connection for ov2640. So we must set the hsync/vsync property (1 means
active high).
Otherwise, the connection would be seen as BT.656 or BT.1120.
