----------------------------



What:	Support for driver specific ioctls in the pwc driver (everything

	defined in media/pwc-ioctl.h)

When:	3.3

Why:	This stems from the v4l1 era, with v4l2 everything can be done with

	standardized v4l2 API calls

Who:	Hans de Goede <hdegoede@redhat.com>



----------------------------



What:	Driver specific sysfs API in the pwc driver

When:	3.3

Why:	Setting pan/tilt should be done with v4l2 controls, like with other

	cams. The button is available as a standard input device

Who:	Hans de Goede <hdegoede@redhat.com>



----------------------------



What:	Driver specific use of pixfmt.priv in the pwc driver

When:	3.3

Why:	The .priv field never was intended for this, setting a framerate is

	support using the standardized S_PARM ioctl

Who:	Hans de Goede <hdegoede@redhat.com>



----------------------------



What:	Software emulation of arbritary resolutions in the pwc driver

When:	3.3

Why:	The pwc driver claims to support any resolution between 160x120

	and 640x480, but emulates this by simply drawing a black border

	around the image. Userspace can draw its own black border if it

	really wants one.

Who:	Hans de Goede <hdegoede@redhat.com>



----------------------------



What:	For VIDIOC_S_FREQUENCY the type field must match the device node's type.

	If not, return -EINVAL.

When:	3.2
