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. Changes since V2: - remove SUPERH Kconfig dependency - move sh_mobile_ceu.h to include/media - add board callback support with enable_camera()/disable_camera() - add support for declare_coherent_memory - rework video memory limit - more verbose error messages Changes since V1: - fixed the CEU driver to work with the newly updated patches Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@pengutronix.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
