This patch adds new V4L2_CAP_VIDEO_M2M and V4L2_CAP_VIDEO_M2M_MPLANE capability flags that are intended to be used for memory-to-memory (M2M) devices, instead of ORed V4L2_CAP_VIDEO_CAPTURE and V4L2_CAP_VIDEO_OUTPUT. V4L2_CAP_VIDEO_M2M flag is added at the drivers, CAPTURE and OUTPUT capability flags are left untouched and will be removed in future, after a transition period required for existing applications to be adapted to check only for V4L2_CAP_VIDEO_M2M.

The V4L2_CID_ISO_SENSITIVITY control menu values should be standard ISO values multiplied by 1000. Multiply all menu items by 1000 so ISO is properly reported as 50...3200 range. This applies to kernels 3.5+. Cc: stable@vger.kernel.org Signed-off-by:

G_PARM should only be enabled if: - vidioc_g_parm is present - or: it is a video node and vidioc_g_std or tvnorms are set. Without this additional check v4l2-compliance would complain about being able to use g_parm when it didn't expect it. Signed-off-by:

The g_mbus_fmt operation only needs to return the current mbus frame format and doesn't need to configure the hardware to do so. Fix it to avoid requiring the chip to be powered on when calling the operation. Signed-off-by:

There will be no soc_camera_device instance with a soc-camera device is used with a non soc-camera host, so we won't be able to pass the soc_camera_device fake platform device to board code. Pass the physical device instead. The argument is currently not used by any board file so this is safe. Signed-off-by:

The soc-camera module exports functions that are needed by soc-camera client drivers even when not running in soc-camera mode. Replace the platform_driver_probe() with a platform_driver_register() call to avoid module load failures if no soc-camera device is present. 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:

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] ...
