Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

V4L/DVB (4861): Remove the need of a STD array for drivers using video_ioctl2 video_ioctl2 will auto-generate standard entries at ENUM_FMT. Also, now, a driver may return a subset of the video array at the return, to be stored as the current_norm. For example, a driver may ask for V4L2_STD_PAL. At return, driver may change it to V4L2_STD_PAL_B. This way, a futher call to G_STD will return the exact detected video std. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

V4L/DVB (4190): Add helper functions for control processing to v4l2-common. Control processing is often duplicated in the various drivers. Unfortunately, simple things like the names of controls are often different between drivers, even though it is the same controls. Adding in the new extended controls and the need for having control helper functions became apparent. Several functions have now been added to v4l2-common to do things like filling the v4l2_queryctrl and v4l2_querymenu structs, to check for valid control input and to move to the next control when enumerating over all controls.

We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

V4L/DVB (4190): Add helper functions for control processing to v4l2-common. Control processing is often duplicated in the various drivers. Unfortunately, simple things like the names of controls are often different between drivers, even though it is the same controls. Adding in the new extended controls and the need for having control helper functions became apparent. Several functions have now been added to v4l2-common to do things like filling the v4l2_queryctrl and v4l2_querymenu structs, to check for valid control input and to move to the next control when enumerating over all controls.

V4L/DVB (5304): Improve chip matching in v4l2_register The chip matching in struct v4l2_register for VIDIOC_DBG_G/S_REGISTER was rather primitive. It could not be extended to other busses besides i2c and it lacked a way to. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.
