-What: Video4Linux API 1 ioctls and from Video devices.
-When: kernel 2.6.38
-Files: include/linux/videodev.h
-Check: include/linux/videodev.h
-Why: V4L1 AP1 was replaced by V4L2 API during migration from 2.4 to 2.6
- series. The old API have lots of drawbacks and don't provide enough
- means to work with all video and audio standards. The newer API is
- already available on the main drivers and should be used instead.
- Newer drivers should use v4l_compat_translate_ioctl function to handle
- old calls, replacing to newer ones.
- Decoder iocts are using internally to allow video drivers to
- communicate with video decoders. This should also be improved to allow
- V4L2 calls being translated into compatible internal ioctls.
- Compatibility ioctls will be provided, for a while, via
- v4l1-compat module.

What: Video4Linux obsolete drivers using V4L1 API
-When: kernel 2.6.38
-Files: drivers/staging/cpia/* drivers/staging/stradis/*
-Check: drivers/staging/cpia/cpia.c drivers/staging/stradis/stradis.c
+When: kernel 2.6.39
+Files: drivers/staging/se401/* drivers/staging/usbvideo/*
+Check: drivers/staging/se401/se401.c drivers/staging/usbvideo/usbvideo.c
Why: There are some drivers still using V4L1 API, despite all efforts we've done
to migrate. Those drivers are for obsolete hardware that the old maintainer
didn't care (or not have the hardware anymore), and that no other developer
could find any hardware to buy. They probably have no practical usage today,
and people with such old hardware could probably keep using an older version
- of the kernel. Those drivers will be moved to staging on 2.6.37 and, if nobody
- care enough to port and test them with V4L2 API, they'll be removed on 2.6.38.

+
+What: Video4Linux: Remove obsolete ioctl's
+When: kernel 2.6.39
+Files: include/media/videodev2.h
+Why: Some ioctl's were defined wrong on 2.6.2 and 2.6.6, using the wrong
+ type of R/W arguments. They were fixed, but the old ioctl names are
+ still there, maintained to avoid breaking binary compatibility:
+ #define VIDIOC_OVERLAY_OLD _IOWR('V', 14, int)
+ #define VIDIOC_S_PARM_OLD _IOW('V', 22, struct v4l2_streamparm)
+ #define VIDIOC_S_CTRL_OLD _IOW('V', 28, struct v4l2_control)
+ #define VIDIOC_G_AUDIO_OLD _IOWR('V', 33, struct v4l2_audio)
+ #define VIDIOC_G_AUDOUT_OLD _IOWR('V', 49, struct v4l2_audioout)
+ #define VIDIOC_CROPCAP_OLD _IOR('V', 58, struct v4l2_cropcap)
+ There's no sense on preserving those forever, as it is very doubtful
+ that someone would try to use a such old binary with a modern kernel.
+ Removing them will allow us to remove some magic done at the V4L ioctl
+ handler.

+What: CS5535/CS5536 obsolete GPIO driver
+When: June 2011
+Files: drivers/staging/cs5535_gpio/*
+Check: drivers/staging/cs5535_gpio/cs5535_gpio.c
+Why: A newer driver replaces this; it is drivers/gpio/cs5535-gpio.c, and
+ integrates with the Linux GPIO subsystem. The old driver has been
+ moved to staging, and will be removed altogether around 2.6.40.
+ Please test the new driver, and ensure that the functionality you
+ need and any bugfixes from the old driver are available in the new
+ one.

+ What: CONFIG_ACPI_PROCFS_POWER
+ When: 2.6.39
+ Why: sysfs I/F for ACPI power devices, including AC and Battery,
+ has been working in upstream kenrel since 2.6.24, Sep 2007.
+ In 2.6.37, we make the sysfs I/F always built in and this option

Who: Jean Delvare <khali@linux-fr.org>
----------------------------
+
+What: cancel_rearming_delayed_work[queue]()
+When: 2.6.39
+
+Why: The functions have been superceded by cancel_delayed_work_sync()
+ quite some time ago. The conversion is trivial and there is no
+ in-kernel user left.
+Who: Tejun Heo <tj@kernel.org>
+
+----------------------------
+
+What: Legacy, non-standard chassis intrusion detection interface.
+When: June 2011
+Why: The adm9240, w83792d and w83793 hardware monitoring drivers have
+ legacy interfaces for chassis intrusion detection. A standard
+ interface has been added to each driver, so the legacy interface
+ can be removed.
