From 7c3a2066aa99b9e6c725803fd153ee8895219dba Mon Sep 17 00:00:00 2001 From: Michael Grzeschik Date: Mon, 9 Aug 2010 11:57:04 -0300 Subject: [PATCH] V4L/DVB: mx2_camera: remove emma limitation for RGB565 In the current source status the emma has no limitation for any PIXFMT since the data is parsed raw and unprocessed into the memory.
