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