sysfs is a possibility but I thought Stephen's initial concern was that I 
was adding too many of these proc files and that they were creating a 
potential API.  sysfs will result in a lot more files with its 
value-per-file model and I think sysfs and proc are similar in "APIness". 
So it's not clear to me how going to sysfs would address Stephen's point. 
The remove-a-few plus move-to-debugfs proposal was in order to end up with 
fewer files in a non-API filesystem.

As these builtin switches become more common I expect an official way to 
represent and access them will emerge but maybe it's not a good idea to 
introduce a sysfs model for them as part of this driver submission.
