2009-03-30V4L/DVB (11261): saa7146: Remove buffer type check from vidioc_g_parmTrent Piepho
The v4l2-ioctl core now only allows buffer types for which the corresponding ->vidioc_try_fmt_xxx() methods are defined to be used with vidioc_(g|s)_parm. The driver was only allowing VIDEO_CAPTURE buffers for g_parm, but since the driver defines ->vidioc_try_fmt_vid_overlay() it will now allow VIDEO_OVERLAY buffers as well. This should be fine as the fields the driver fills in, readbuffers and frame rate, aren't wrong for VIDEO_OVERLAY buffers.

2009-03-30V4L/DVB (10814): saa7146: some small fixesTrent Piepho
vidioc_enum_fmt_vid_overlay() did nothing but call vidioc_enum_fmt_vid_cap(), so just make saa7146_video_ioctl_ops.vidioc_enum_fmt_vid_overlay point to vidioc_enum_fmt_vid_cap() and get ride of vidioc_enum_fmt_vid_overlay(). Have gparm use v4l2_video_std_frame_period to fill in the frame period instead of just assuming PAL.

2009-03-30V4L/DVB (10499): saa7146: convert saa7146 and mxb in particular to v4l2_subdev.Hans Verkuil
Modified mxb to load the i2c modules through v4l2_subdev. So no more probing. Modified tea6415c and tea6420 to use the standard routing ops to do the routing, rather than using private commands. Dropped the private commands from tda9840 (they were never used except during initialization of the module). Added saa7146 support for VIDIOC_DBG_G_CHIP_IDENT. Converted saa5246a and saa5249 to v4l2_subdev. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2009-01-02V4L/DVB (10138): v4l2-ioctl: change to long return type to match unlocked_ioctl.Hans Verkuil
Since internal to v4l2 the ioctl prototype is the same regardless of it being called through .ioctl or .unlocked_ioctl, we need to convert it all to the long return type of unlocked_ioctl. Thanks to Jean-Francois Moine for posting an initial patch for this and thus bringing it to our attention.

2008-12-29V4L/DVB (9503): v4l: remove inode argument from video_usercopyHans Verkuil

2008-10-21V4L/DVB (9330): Get rid of inode parameter at v4l_compat_translate_ioctl()Mauro Carvalho Chehab
The inode parameter at v4l_compat_translate_ioctl() were just passed over several places just to keep compatible with fops.ioctl. However, it weren't used anywere.

2008-07-27V4L/DVB (8546): saa7146: fix read from uninitialized memoryHans Verkuil
The offset field of the scatterlist entry *after* the last valid scatterlist entry was used instead of the first scatterlist entry (as was the intention of this code). This worked fine until the kzalloc of the sglist was replaced with kmalloc and sg_init_table only zeroed the exact needed length. Apparently kzalloc zeroes a bit more than is strictly necessary so the offset field was always 0 in the past. But now the offset field was suddenly random and this led to broken captures.

2007-10-09V4L/DVB (6252): Adapt drivers to use the newer videobuf modulesMauro Carvalho Chehab
PCI-dependent videobuf_foo methods were renamed as videobuf_pci_foo. Also, videobuf_dmabuf is now part of videobuf-dma-sg private struct. So, to access it, a subroutine call is needed. This patch renames all occurences of those function calls to be consistent with the video-buf split.

2006-03-24V4L/DVB (3516): Make video_buf more genericMauro Carvalho Chehab
Video_buf were concerned to allow PCI devices to be used as video capture devices.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
