22 #define __PVRUSB2_HDW_INTERNAL_H
26 This header sets up all the internal structures and definitions needed to
27 track and coordinate the driver's interaction with the hardware. ONLY
28 source files which actually implement part of that whole circus should be
29 including this header. Higher levels, like the external layers to the
30 various public APIs (V4L, sysfs, etc) should NOT ever include this
31 private, internal header. This means that pvrusb2-hdw, pvrusb2-encoder,
32 etc will include this, but pvrusb2-v4l should not.
