[media] videobuf2-dma-contig: make cookie() return a pointer to dma_addr_t

2011-03-22T22:41:58+00:00

dma_addr_t may not fit into void* on some architectures. To be safe, make
vb2_dma_contig_cookie() return a pointer to dma_addr_t and dereference it
in vb2_dma_contig_plane_paddr() back to dma_addr_t.

[media] v4l: soc-camera: Store negotiated buffer settings

2011-03-22T22:41:55+00:00

This fixes the problem in which a host driver
sets a personalized sizeimage or bytesperline field,
and gets ignored when doing G_FMT.

[media] rc/keymaps: Rename Hauppauge table as rc-hauppauge

2011-03-22T22:24:14+00:00

There are two "hauppauge-new" keymaps, one with protocol
unknown, and the other with the protocol marked accordingly.
However, both tables are miss-named.

Also, the old rc-hauppauge-new is broken, as it mixes
three different controllers as if they were just one.

This patch solves half of the problem by renaming the
correct keycode table as just rc-hauppauge. This table
contains the codes for the four different types of
remote controllers found on Hauppauge cards, properly
mapped with their different addresses.

 create mode 100644 drivers/media/rc/keymaps/rc-hauppauge.c
 delete mode 100644 drivers/media/rc/keymaps/rc-rc5-hauppauge-new.c

[media] v4l2: use new flag to enable core priority handling

2011-03-22T19:38:16+00:00

Rather than guess which driver supports core priority handling, require drivers
that do to explicitly set the V4L2_FL_USE_FH_PRIO flag in video_device.

Updated the core prio handling accordingly and set the flag in the three
drivers that do.

[media] v4l2-device: add kref and a release function

2011-03-22T19:38:05+00:00

The video_device struct has proper ref counting and its release function
will be called when the last user releases it. But no such support was
available for struct v4l2_device. This made it hard to determine when a
USB driver can release the device if it has multiple device nodes.

With one device node it is easy of course, since when the device node is
released, the whole device can be released.

This patch adds refcounting to v4l2_device. When registering device nodes
the v4l2_device refcount will be increased, when releasing device nodes
it will be decreased. The (optional) release function will be called when
the last device node was released.

[media] v4l2-ioctl: add priority handling support

[media] v4l2-fh: add v4l2_fh_is_singular

2011-03-22T19:37:58+00:00

Several drivers need to do something when the first filehandle is opened
or the last filehandle is closed. Most implement some use count mechanism,
but if they use v4l2_fh, then you can also just check if this is the only
filehandle for the device node. A simple helper function can do this.

[media] v4l2-fh: add v4l2_fh_open and v4l2_fh_release helper functions

2011-03-22T19:37:57+00:00

Add two new functions: v4l2_fh_open allocates and initializes a struct v4l2_fh
based on a struct file pointer and v4l2_fh_release releases and frees a struct
v4l2_fh.
