* [media] tvp5150: COMPOSITE0 input should not force-enable TV modePaul Walmsley2010-10-211-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When digitizing composite video from a analog videotape source using the TVP5150's first composite input channel, the captured stream exhibits tearing and synchronization problems[1]. It turns out that commit c0477ad9feca01bd8eff95d7482c33753d05c700 caused "TV mode" (as opposed to "VCR mode" or "auto-detect") to be forcibly enabled for both composite inputs. According to the chip documentation[2], "TV mode" disables a "chrominance trap" input filter, which appears to be necessary for high-quality video capture from an analog videotape source. [ Commit c7c0b34c27bbf0671807e902fbfea6270c8f138d subsequently restricted the problem to the first composite input, apparently inadvertently. ] Since any type of composite signal source can be connected to the TVP5150's first composite input, unconditionally forcing "TV mode" isn't correct. There doesn't appear to be a good way for applications to tell the driver what is connected. Fortunately, the TVP5150 has an operating mode auto-detection feature, which, when enabled, should cause the TVP5150 to auto-detect whether it should use "VCR mode" or "TV mode". Enabling operating mode auto-detection improved video capture quality significantly[3]. Therefore, fix this bug by using operating mode auto-detection. (Also, while here, fix a CodingStyle issue.) For those users who may find this patch via a mailing list archive but who are not able to upgrade to a kernel with a fixed driver: the TVP5150's S-Video and second composite input sources have auto-detection enabled, so you may wish to try using those -- if available on your device -- until this fix makes it a downstream distribution near you. 1.

* [media] uvcvideo: Fix bogus XU controls informationLaurent Pinchart2010-10-211-0/+41
| | | | | | | | | | | | | | | | | XU control information is supposed to be entirely discoverable using standard UVC queries. As some devices report bogus information (such as reporting a read-only control as being read-write), add a fixup table for XU controls. This table can also be used to selectively disable requests supposed to be supported by all XU controls (GET_MIN, GET_MAX, GET_DEF, GET_RES) but not correctly (or at all) supported by the device. The table currently disables GET_CUR on the Logitech motor control XU pan/tilt controls.

* [media] uvcvideo: Remove sysadmin requirements for UVCIOC_CTRL_MAPMartin Rubli2010-10-214-6/+19
| | | | | | | | | | | | | This patch removes the sysadmin requirements for UVCIOC_CTRL_MAP (and the stub implementation of UVCIOC_CTRL_ADD). This requirement no longer makes sense with the new XU control access mechanisms since XU controls can be accessed without adding control mappings first. A maximum number (currently 1024) of control mappings per device is enforced to avoid excess memory consumption caused by careless user space applications.

* [media] uvcvideo: Hardcode the index/selector relationship for XU controlsLaurent Pinchart2010-10-214-270/+240
| | | | | | | | | | | | | | | | | | | | | | | | Devices advertise XU controls using a bitmask, in which each bit corresponds to a control. The control selector, used to query the control, isn't available in the USB descriptors. All known UVC devices use control selectors equal to the control bit index plus one. Hardcode that relationship in the driver, making the UVCIOC_CTRL_ADD ioctl obsolete. All necessary information about XU controls can be obtained by the driver at enumeration time. The UVCIOC_CTRL_ADD ioctl is still supported for compatibility reasons, but now always returns -EEXIST. Finally, control mappings are now on a per-device basis and no longer global. As this changes the userspace interface, bump the driver version number to 1.0.0 (it was about time).
