Guennadi Liakhovetski c8329accf7 V4L/DVB (10672): sh_mobile_ceu_camera: include NV* formats into the format list only once.
Currently, if an soc-camera device, connected to the sh_mobile_ceu_camera
camera host driver, supports several formats from the UYVY, VYUY, YUYV, YVYU
set, the driver would add four NV* formats for each of them. This patch fixes
this misbehaviour.

sh_mobile_ceu_camera.c support for signal polarity flags isn't platform
dependent, provide them locally. Only the bus width is implementation
specific.

We anyway don't follow the s_fmt_vid_cap / g_fmt_vid_cap / try_fmt_vid_cap
naming, and soc-camera is so far only about video capture, let's simplify
operation names a bit further. set_fmt_cap / try_fmt_cap wasn't a very good
choice too.

Guennadi Liakhovetski 25c4d74ea6 V4L/DVB (9787): soc-camera: let camera host drivers decide upon pixel format
Pixel format requested by the user is not necessarily the same, as what
a sensor driver provides. There are situations, when a camera host driver
provides the required format, but requires a different format from the
sensor. Further, the list of formats, supported by sensors is pretty static
and can be pretty good described with a constant list of structures. Whereas
decisions, made by camera host drivers to support requested formats can be
quite complex, therefore it is better to let the host driver do the work.

Kay Sievers af128a102c V4L/DVB (9521): V4L: struct device - replace bus_id with dev_name(), dev_set_name()
This patch is part of a larger patch series which will remove
the "char bus_id[20]" name string from struct device. The device
name is managed in the kobject anyway, and without any size
limitation, and just needlessly copied into "struct device".

To set and read the device name dev_name(dev) and dev_set_name(dev)
must be used. If your code uses static kobjects, which it shouldn't
do, "const char *init_name" can be used to statically provide the
name the registered device should have. At registration time, the
init_name field is cleared, to enforce the use of dev_name(dev) to
access the device name at a later time.

We need to get rid of all occurrences of bus_id in the entire tree
to be able to enable the new interface. Please apply this patch,
and possibly convert any remaining remaining occurrences of bus_id.

We want to submit a patch to -next, which will remove bus_id from
"struct device", to find the remaining pieces to convert, and finally
switch over to the new api, which will remove the 20 bytes array
and does no longer have a size limitation.

Thanks,
Kay

Magnus Damm 51354cc3e0 V4L/DVB (9244): video: improve sh_mobile_ceu buffer handling
This patch improves the buffer handling in the sh_mobile_ceu driver.

Instead of marking all queued buffers as VIDEOBUF_ACTIVE the code now
marks queued-but-not-active buffers as VIDEOBUF_QUEUED and buffers
involved in dma as VIDEOBUF_ACTIVE. The code is also updated with
code to cancel active buffers, thanks to Morimoto-san.

Magnus Damm 0d3244d643 V4L/DVB (8342): 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.

 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
