Re: V4L2 to-do list, No.2

Been updating the specs. Haven't released the new
videodevX yet.

Added 
V4L2_PIX_FMT_YUV420
V4L2_PIX_FMT_YUV410
V4L2_PIX_FMT_YUV422P
V4L2_PIX_FMT_YUV411P
V4L2_PIX_FMT_NV12
Removed
V4L2_PIX_FMT_YVU422P
V4L2_PIX_FMT_YVU411P
The symbols are still in the header file, but removed
from the spec. I am assuming we don't need them. Speak
up if you know otherwise.

Made the new frequency ioctls VIDIOC_G_FREQUENCY and
VIDIOC_S_FREQUENCY. I like it better-- it fits better
than "FREQ2". Will also add Gerd's other spec improvements.

Because Gerd's videodev has a new driver interface (been 
calling it the Knorr Model to myself), I want to sync the
API first and release a videodevX that's API compatible,
then switch to the Knorr Model. Hmm, and somehow encourage
driver porting.


Alan, is there any reason why the Knorr Model couldn't be
incorporated into 2.4.(10?)? That would be ideal. Then we
don't have to maintain it separately.

Bill.
