This seems more logical to me:
enum v4l2_focus_mode {
V4L2_FOCUS_MANUAL = 0,
V4L2_FOCUS_AUTO_NORMAL = 1,
V4L2_FOCUS_AUTO_MACRO = 2,
};
At least this maps the current boolean values correctly. I'm not sure from
your decription what the fourth auto focus mode is supposed to be.
But I think it might be better to have a separate control that allows you to
set the auto-focus mode. I can imagine that different devices might have
different auto-focus modes.
I've CC-ed Laurent since this is more his field than mine.
