2008-06-21videodev: simplify and fix standard enumerationHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> VIDIOC_ENUMSTD did not return all the PAL/SECAM/NTSC variants: it just returned one single PAL/SECAM/NTSC standard without separate entries for the trickier standards like NTSC-JP. Changed the code so that it behaves better. Also simplified the if/switch statements into a common standards lookup table. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2008-06-21ivtv: yuv decoder lock fix (2)Hans Verkuil
From: Ian Armstrong <ian@iarmst.demon.co.uk> The IVTV_IOC_DMA_FRAME ioctl fails to correctly 'start' the decoder. Although yuv output will be correct, some functions which should be disabled while the decoder is in use remain enabled. This can result in hardware registers being corrupted, causing problems with the mpeg decoder. This patch ensures the decoder 'start' sequence is called, disabling these functions until the device is closed.

2008-06-21ivtv: yuv decoder lock fixHans Verkuil
From: Ian Armstrong <ian@iarmst.co.uk> write() operations to the yuv device may not always 'start' the decoder. Although yuv output will be correct, some functions which should be disabled while the decoder is in use remain enabled. This can result in hardware registers being corrupted, causing problems with the mpeg decoder. This patch simply moves the existing decoder 'start' sequence to earlier in the write() handler.

2008-06-21ivtv/cx18: fix video_temporal_filter handlingHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> If the capture is scaled, then the video_temporal_filter is set to 0 by the cx2341x.c module since otherwise you would get ghosting. However, this was also done in the VIDIOC_S_FMT ioctl which meant that the video_temporal_filter control was reset to 0 or 8 each time S_FMT was called. This was old code that should have been removed a long time ago. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2008-06-20 Introduce "index" attribute for persistent video4linux device nodesMauro Carvalho Chehab
From: brandon@ifup.org <brandon@ifup.org> A number of V4L drivers have a mod param to specify their preferred minors. This is because it is often desirable for applications to have a static /dev name for a particular device. However, using minors has several disadvantages: 1) the requested minor may already be taken 2) using a mod param is driver specific 3) it requires every driver to add a param 4) requires configuration by hand This patch introduces an "index" attribute that when combined with udev rules can create static device paths like this: /dev/v4l/by-path/pci-0000\:00\:1d.2-usb-0\:1\:1.0-video0 /dev/v4l/by-path/pci-0000\:00\:1d.2-usb-0\:1\:1.0-video1 /dev/v4l/by-path/pci-0000\:00\:1d.2-usb-0\:1\:1.0-video2 $ ls -la /dev/v4l/by-path/pci-0000\:00\:1d.2-usb-0\:1\:1.0-video0 lrwxrwxrwx 1 root root 12 2008-04-28 00:02 /dev/v4l/by-path/pci-0000:00:1d.2-usb-0:1:1.0-video0 -> ../../video1 These paths are steady across reboots and should be resistant to rearranging across Kernel versions. video_register_device_index is available to drivers to request a specific index number.

2008-06-21cx18: Fix S-Video and Compsite inputs for the Yuan MPC718 and enable card entryAndy Walls
From: Andy Walls <awalls@radix.net> cx18: Fix S-Video and Compsite input settings for the Yuan MPC718 per user reports from Yuri Warczynski <Yuri.Warczynski@gmail.com> and Brian Hope <brian@hopefamily.info> and enable the card entry. The tuner reset GPIO pin is likely incorrect as the tuner firmware cannot be reloaded without a reboot. It is likely the audio routing is done via GPIO which is not implemented yet, as users report audio doesn't work for some inputs. Signed-off-by: Andy Walls <awalls@radix.net>
2008-06-21cx18: Add I2C slave reset via GPIO upon initializationAndy Walls
From: Andy Walls <awalls@radix.net> cx18: Add I2C slave reset via GPIO upon initialization. One user, Michael <msd4824@yahoo.com>, has reported this allows his HVR-1600 EEPROM to be consistently recognized when using (long,) 100 msec delays. The delays in this commit are nominal (10 & 40 msec) and need testing/tuning on boards with I2C problems to find the right values. Signed-off-by: Andy Walls <awalls@radix.net>
2008-06-21cx18: Fix firmware load for case when digital capture happens firstAndy Walls
From: Andy Walls <awalls@radix.net> This is a fix for the case when a digital capture from dvr0 happens first after modprobe, before access to any cx18 v4l2 device nodes. The initial dvb feed start has been changed to load the firmware if not already loaded. Also fixed a use counter to correct dvb feed accounting if starting the transport DMA fails.

From: Andy Walls <awalls@radix.net> Fix the cx18-cards.c structures for the HVR-1600 to reflect that audio Line In 2 and FM radio audio go to AIN3 and AIN4 of the CS5345 mux respectively. Verified by physical inspection of an HVR-1600MCE, by listening to FM broadcasts with the HVR-1600MCE, and by comparing with the card definition for a PVR-150 in ivtv.
