Hi, Peter & Daniel

Sorry about that I'm not clear enough to add a new subsystem into QEMU, could you give me more hint?

   Separate v1 patch set into 2 parts:
     Introduce camera subsystem (this one).
     USB desc fix and UVC.
   Add maintainer infomation.

v1:
1, The full picture of this patch set:
    +---------+       +------------+     +---------------+

   |builtin(done)|     |v4l2(done)|        |other drivers|
   +-------------+     +----------+        +-------------+

With this patch set, We can run a desktop VM (Ex Ubuntu-2004), several camera
APPs(cheese, kamoso, guvcview and qcam) work fine.

Some works still in working:
   1, hot-plug
   2, compat with live migration
   3, several actions defined in UVC SPEC

Zhenwei Pi (2):
   camera: Introduce camera subsystem and builtin driver
   camera: v4l2: Introduce v4l2 camera driver
