From 22a4b32d43ab24e459a3d454f2bd89ec0193056d Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Thu, 17 Jul 2008 00:59:28 +0200 Subject: sh_mobile_ceu_camera: Add SuperH Mobile CEU driver V3 This is V3 of the SuperH Mobile CEU soc_camera driver. The CEU hardware block is configured in a transparent data fetch mode, frames are captured from the attached camera and written to physically contiguous memory buffers provided by the newly added videobuf-dma-contig queue. Tested on sh7722 and sh7723 processors.
