From 2ffab02fea5880da284dc5511479b25a796a8dee Mon Sep 17 00:00:00 2001 From: Luca Risolia Date: Sat, 25 Feb 2006 06:50:47 +0000 Subject: [PATCH] USB: SN9C10x driver updates SN9C10x driver updates. Changes: + new, - removed, * cleanup, @ bugfix @ Fix stream_interrupt() @ Fix vidioc_enum_input() and split vidioc_gs_input() @ Need usb_get|put_dev() when disconnecting, if the device is open * Use wait_event_interruptible_timeout() instead of wait_event_interruptible() when waiting for video frames * replace wake_up_interruptible(&wait_stream) with wake_up(&wait_stream) * Cleanups and updates in the documentation + Use per-device sensor structures + Add support for PAS202BCA image sensors + Add frame_timeout module parameter Signed-off-by: Luca Risolia Signed-off-by: Greg Kroah-Hartman --- Documentation/usb/sn9c102.txt | 11 ++ drivers/usb/media/Makefile | 5 +- drivers/usb/media/sn9c102.h | 23 +++- drivers/usb/media/sn9c102_core.c | 170 +++++++++++++---------- drivers/usb/media/sn9c102_ov7630.c | 33 +++-- drivers/usb/media/sn9c102_pas202bca.c | 238 +++++++++++++++++++++++++++++++++ drivers/usb/media/sn9c102_pas202bcb.c | 2 +- drivers/usb/media/sn9c102_sensor.h | 15 ++- drivers/usb/media/sn9c102_tas5110c1b.c | 14 +- drivers/usb/media/sn9c102_tas5130d1b.c | 12 +- 10 files changed, 416 insertions(+), 107 deletions(-) create mode 100644 drivers/usb/media/sn9c102_pas202bca.c diff --git a/Documentation/usb/sn9c102.txt b/Documentation/usb/sn9c102.txt index c6b76414172c..b957beae5607 100644 --- a/Documentation/usb/sn9c102.txt +++ b/Documentation/usb/sn9c102.txt @@ -196,6 +196,14 @@ Description: Force the application to unmap previously mapped buffer memory 1 = force memory unmapping (save memory) Default: 0 ------------------------------------------------------------------------------- +Name: frame_timeout +Type: uint array (min = 0, max = 64) +Syntax: +Description: Timeout for a video frame in seconds.
