Hi Laurent, I promised to look at the new type names, so here is my opinion: On Monday, December 20, 2010 12:36:26 Laurent Pinchart wrote: <snip> > + > +#define MEDIA_ENTITY_TYPE_SHIFT 16 > +#define MEDIA_ENTITY_TYPE_MASK 0x00ff0000 > +#define MEDIA_ENTITY_SUBTYPE_MASK 0x0000ffff > + > +#define MEDIA_ENTITY_TYPE_DEVNODE (1 << MEDIA_ENTITY_TYPE_SHIFT) > +#define MEDIA_ENTITY_TYPE_DEVNODE_V4L (MEDIA_ENTITY_TYPE_DEVNODE + 1) > +#define MEDIA_ENTITY_TYPE_DEVNODE_FB (MEDIA_ENTITY_TYPE_DEVNODE + 2) > +#define MEDIA_ENTITY_TYPE_DEVNODE_ALSA (MEDIA_ENTITY_TYPE_DEVNODE + 3) > +#define MEDIA_ENTITY_TYPE_DEVNODE_DVB (MEDIA_ENTITY_TYPE_DEVNODE + 4) > + > +#define MEDIA_ENTITY_TYPE_V4L2_SUBDEV (2 << MEDIA_ENTITY_TYPE_SHIFT) > +#define MEDIA_ENTITY_TYPE_V4L2_SUBDEV_SENSOR (MEDIA_ENTITY_TYPE_V4L2_SUBDEV + 1) > +#define MEDIA_ENTITY_TYPE_V4L2_SUBDEV_FLASH (MEDIA_ENTITY_TYPE_V4L2_SUBDEV + 2) > +#define MEDIA_ENTITY_TYPE_V4L2_SUBDEV_LENS (MEDIA_ENTITY_TYPE_V4L2_SUBDEV + 3) > + > +#define MEDIA_ENTITY_FLAG_DEFAULT (1 << 0) > + > +#define MEDIA_LINK_FLAG_ENABLED (1 << 0) > +#define MEDIA_LINK_FLAG_IMMUTABLE (1 << 1) > + > +#define MEDIA_PAD_FLAG_INPUT (1 << 0) > +#define MEDIA_PAD_FLAG_OUTPUT (1 << 1) Using V4L2_SUBDEV instead of just SUBDEV is definitely an improvement. However, I think the defines are getting way too long and I would propose to use the ME_ prefix instead of MEDIA_ENTITY_. Also ML_ instead of MEDIA_LINK_ and MP_ instead of MEDIA_PAD_. That way it is less of an alphabet soup when reading code.
