Kuninori Morimoto 5cf93f1dca V4L/DVB (13128): sh_mobile_ceu_camera: add VBP error support
If CEU driver can not receive data from camera,
CETCR has VBP error state.
Then, CEU is stopped and cure operation is needed.
This patch add VBP error cure operation.

The initial soc-camera scaling and cropping implementation turned out to be

Guennadi Liakhovetski 904078f16f V4L/DVB (12522): sh-mobile-ceu-camera: implement host-side cropping
Not all video capture devices can configure arbitrary cropping, whereas the
CEU module on SuperH CPUs can crop with pixel precision. However, we want to
use camera cropping if possible to save bandwidth and increase the frame-rate.
This patch verifies whether the camera managed to crop exactly the requested
rectangle, and if not, uses host-side cropping. To be able to crop on CEU we
have to preserve camera rectangle too, for which the host_priv member in
struct soc_camera_device is used. We now allocate memory dynamically, thus we
have to use the .put_formats() method from struct soc_camera_host_ops to free
it.

Patch

[PATCH] video: use videobuf_waiton() in sh_mobile_ceu free_buffer()

was not quite correct. It closed a race, but introduced a potential
lock-up, if for some reason an interrupt does not come. This has been
observed in tests with tw9910. This patch safely dequeues buffers without
waiting for their completion. It also moves a buffer state assignment
under a spinlock to make it atomic with queuing of the buffer.

Pixel format requested by the user is not necessarily the same, as what

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

Paul Mundt 01c1e4ca8e V4L/DVB (8609): media: Clean up platform_driver_unregister() bogosity.
So, platform_driver_unregister() doesn't actually have a return value,
nor do any of the void __exit routines. It's reassuring to know that
people copy and paste blindly. This completely blew up my compiler.

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
