| | * | | V4L/DVB: Add closed captioning support for the HVR-950qDevin Heitmueller2010-08-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add NTSC closed captioning support for au0828 based products. Note that this also required reworking the locking to support streaming on both the video and VBI devices (the logic for which I copied from my changes made to the em28xx several months ago).

| | * | | V4L/DVB: ivtv: Automatic firmware reloadIan Armstrong2010-08-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the firmware has failed, this patch will automatically reload & restart the card. The previous card state will be restored on a successful restart. Firmware reload will only happen if neither the encoder or decoder is active. If the card is busy then behaviour is as before, returning -EIO on device access until the reload can occur. On cards that support video output, coloured bars will be displayed during the reload. Andy Walls (ivtv maintainer and patch committer) made minor tweaks to comments and the logged messages, but nothing substantial otherwise.

| | * | | V4L/DVB: ivtv: Add firmare monitoring and debug mode to ignore firmware problemsIan Armstrong2010-08-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | >From Ian's e-mail: When a device is opened the firmware state will be checked. If it isn't responding then the open will fail with -EIO. Due to the nature of the hardware, a single failed check will block everything since we don't know exactly what has failed. A side effect of this is the blocking of debug access, so an additional debug level has been created which allows the block to be bypassed. Andy Walls' modifications: I modified Ian's patch to add a separate fw_debug module parameter to change the driver's behavior, as opposed to using the normal debug module parameter. The fw_debug module parameter is only available when CONFIG_VIDEO_ADV_DEBUG is set. I also made some minor whitespace adjustments and changed some warning messages to be a bit more specific. s/happy/glad/g Signed-off-by: Ian Armstrong <ian@iarmst.demon.co.uk> Signed-off-by: Andy Walls <awalls@md.metrocast.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| * | V4L/DVB: FusionHDTV: Use quick reads for I2C IR device probingJean Delvare2010-06-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | IR support on FusionHDTV cards is broken since kernel 2.6.31. One side effect of the switch to the standard binding model for IR I2C devices was to let i2c-core do the probing instead of the ir-kbd-i2c driver. There is a slight difference between the two probe methods: i2c-core uses 0-byte writes, while the ir-kbd-i2c was using 0-byte reads. As some IR I2C devices only support reads, the new probe method fails to detect them. For now, revert to letting the driver do the probe, using 0-byte reads. In the future, i2c-core will be extended to let callers of i2c_new_probed_device() provide a custom probing function. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: "Timothy D.
