Thanks a lot for this reminder. I forgot to check the status.
The latest one is the v4, but LP3943 PWM driver code is same as v3.
Update from v3 to v4: Move the driver description from the documentation to the MFD driver file.
There are two things to be ACKed for v4. One is the PWM driver. (https://lkml.org/lkml/2013/9/25/11) The other is the documentation. (https://lkml.org/lkml/2013/9/25/10)
Thanks, Milo
