Subject: [RFC PATCHv4 0/4] Support for OTP memory

Hi all,

This series of the OTP memory support has been updated since v3 with the
following main changes:

	- The device specific ioctl() has now been eliminated and an
	OTP_LOCK_AREA ioctl() has been added that uses the new lock_word()
	operation to perform locking of OTP.
	- The read_word/write_word operations are now per-device operations
	rather than per-region.
	- A word_size attribute has been added so that users can get the OTP
	word size (useful for the area locking).
	- Regions can have labels (a bit like partition names).
	- The sysfs show/store functions now take a backend module reference
	before accessing the operations to prevent a possible invalid
	reference when the backend module is unloaded.

Thanks,

Jamie Iles (4):
  drivers/otp: add initial support for OTP memory
  drivers/otp: add support for Picoxcell PC3X3 OTP
  Blackfin: add the OTP device as a platform device
  drivers/otp: convert bfin otp to generic OTP
