You still have quite a few style/typo issues, an inconsistent use of -1 for errors.
Sleep times are very odd, e.g.
sleep_dur = (book << 8) + page; msleep(sleep_dur);
or
usleep_range(delay_time*1000, delay_time*1000);
and the mutex uses are not clear.
Please go through all the comments, I had to repeat myself a number of times...

Not looked at the code properly yet but as previously noted you are adding a new DT binding so you need to send a patch documenting that binding along with the driver.
