Hi,
I've updated this series following some great feedback from Greg and Mike, and aside from the code quality improvements, the main changes since v2 are:
- The OTP regions don't live directly in /sys/bus/otp/devices anymore but just as a child device of the OTP device. - CONFIG_OTP_WRITE_ENABLE has been created that replaces the bfin-otp specific option and this disables all OTP writing at the higher levels. The PC3X3 OTP driver has also been converted to use this. - Multiple OTP devices can now be registered at the same time. - The bfin-otp driver has been converted to a platform_driver and the relevant Blackfin platforms have had a bfin-otp device added. - The Blackfin OTP is now represented as a single region that does not include the ECC or control bits. This prevents users from accidentally scribbling over those bits.
Greg, Mike, thanks again for taking the time to review, it's much appreciated.
Thanks,
Jamie Iles (4): drivers/otp: add initial support for OTP memory drivers/otp: add support for Picoxcell PC3X3 OTP drivers/otp: convert bfin otp to generic OTP Blackfin: add the OTP device as a platform device
