Think of it like an elegant privacy sticker. The system can read the status of the privacy switch via a GPIO. The ACPI table maps this GPIO to the USB device via _CRS and _DSD descriptors, so the kernel can find it. The userspace applications need to know if the privacy pin is enabled or not. The obvious way to show it to userspace is via the V4L2_CID_PRIVACY control. This patchset implement this functionality. v5: Thanks to all the comments from Laurent! - Allow multiple async_ctrls - Use dev_dbg() for uvc_trace - Major redesing of "Implement UVC_EXT_GPIO_UNIT" - Major redesing of "Implement UVC_QUIRK_PRIVACY_DURING_STREAM" v4: Implement UVC_QUIRK_PRIVACY_DURING_STREAM v3: Thanks to all the comments from Joe Perches - Rework of printk macros v2: Thanks to all the comments from Laurent! - move guid to unit - support entities with no pads - CodeStyle - Irq handling - pr_cont - new ids Ricardo Ribalda (12): media: uvcvideo: Fix race condition handling events media: uvcvideo: Allow more that one asyc_ctrl media: uvcvideo: Move guid to entity media: uvcvideo: Allow extra entities media: uvcvideo: Allow entities with no pads media: uvcvideo: Allow entity-defined get_info and get_cur media: uvcvideo: Implement UVC_EXT_GPIO_UNIT media: uvcvideo: Add Privacy control based on EXT_GPIO media: uvcvideo: Implement UVC_QUIRK_PRIVACY_DURING_STREAM media: uvcvideo: Use dev_ printk aliases media: uvcvideo: New macro uvc_trace_cont media: uvcvideo: use dev_dbg() for uvc_trace() drivers/media/usb/uvc/uvc_ctrl.c | 204 +++++---- drivers/media/usb/uvc/uvc_driver.c | 644 +++++++++++++++++++---------- drivers/media/usb/uvc/uvc_entity.c | 11 +- drivers/media/usb/uvc/uvc_isight.c | 16 +- drivers/media/usb/uvc/uvc_queue.c | 12 +- drivers/media/usb/uvc/uvc_status.c | 32 +- drivers/media/usb/uvc/uvc_v4l2.c | 53 ++- drivers/media/usb/uvc/uvc_video.c | 120 +++--- drivers/media/usb/uvc/uvcvideo.h | 91 ++-- 9 files changed, 767 insertions(+), 416 deletions(-) -- 2.29.2.684.gfbc64c5ab5-goog
