The VIDIOC_DV_TIMINGS_CAP ioctl check wasn't added to determine_valid_ioctls(). This caused this ioctl to always return -ENOTTY. Signed-off-by:

add clock enable and disable in probe and remove functions. Probe will succeed only if the device clock is provided instead of assuming that the clock is always enabled. VPIF clock has to be dealt with during suspend and resume. Implement power management callbacks to VPIF driver to disable/enable clock on suspend/resume respectively. Signed-off-by:

add hardware clipping support for VPIF output data. This is needed as it is possible that the external encoder might get confused between the FF or 00 which are a part of the data and that of the SAV or EAV codes. Signed-off-by:

omap-l138 shares the interrupt between capture and display. Make sure we are able to request for the same irq number by making a shared irq request. Signed-off-by:

change the dm646x specific strings in the driver to make them generic across platforms. In this case change all the strings which have a dm646x connotation to vpif which is a platform independent ip. Signed-off-by:

As the same interrupt is shared between capture and display devices, sometimes we get isr calls where the interrupt might not genuinely belong to capture or display. Hence, add a condition in the isr to check for interrupt ownership and channel number to make sure we do not service wrong interrupts. Signed-off-by:

from commit a8f3c203 restore the mapping scheme for uncached buffers, which was changed in a common scheme for cached and uncached. This apparently was wrong, and was probably intended only for cached buffers. the fix fixes the crash observed while mapping uncached buffers. Signed-off-by:

This driver consists of 2 parts, a generic tea5777 driver and a driver for the Griffin radioSHARK v2 USB radio receiver, which is the only driver using the generic tea5777 for now. This first version only implements FM support, once the the new VIDIOC_ENUM_FREQ_BANDS API is upstream I'll also add AM support. Signed-off-by:

Commit efbceecd, adds a number of helper functions for ctrl related ioctls to v4l2-ioctl.c, these helpers assume that if file->private_data != NULL, it points to a v4l2_fh, which is only the case for drivers which actually use v4l2_fh. This breaks for example bttv which use the "filedata" pointer for its own uses, and now all the ctrl ioctls try to use whatever its filedata points to as v4l2_fh and think it has a ctrl_handler, leading to: [ 142.499214] BUG: unable to handle kernel NULL pointer dereference at 0000000000000021 [ 142.499270] IP: [<ffffffffa01cb959>] v4l2_queryctrl+0x29/0x230 [videodev] [ 142.514649] [<ffffffffa01c7a77>] v4l_queryctrl+0x47/0x90 [videodev] [ 142.517417] [<ffffffffa01c58b1>] __video_do_ioctl+0x2c1/0x420 [videodev] [ 142.520116] [<ffffffffa01c7ee6>] video_usercopy+0x1a6/0x470 [videodev] ... This patch adds the missing test_bit(V4L2_FL_USES_V4L2_FH, &vfd->flags) tests to the ctrl ioctl helpers v4l2_fh paths, fixing the issues with for example the bttv driver. Signed-off-by:

The konica needs a freaking large time (circa 6.5 seconds) to "boot", and does not want to be bothered while doing so, so sleep for 6 seconds, and then query its status register at 100ms intervals until it becomes ready. This removes the "reg_w err: -32" messages shown in dmesg whenever a konica cam gets initialized, and also fixes the camera not working when an app tries to use it directly after it has been plugged in and after a suspend/resume cycle.

1) The gspca-core's suspend/resume code is such that resume being called after a reset is safe / ok. 2) All devices tested sofar seem to need the reset_resume callback to work properly over a suspend 3) The USB-core won't call the reset_resume callback for devices which don't need it Thus it seems the simplest and the best to just add the callback to all sub-drivers, rather then adding the callbacks one-by-one as each driver gets tested with suspend/resume.
