As the ad5398 driver implements the regulator driver API you should send the patch to the appropriate mailing lists. $ ./scripts/get_maintainer.pl -f drivers/regulator/ad5398.c Michael Hennerich <michael.hennerich@xxxxxxxxxx> (supporter:AD5398 CURRENT RE...)

Thank you. I found also a little info here: > http://www.mail-archive.com/davinci-linux-open-source@xxxxxxxxxxxxxxxxxxxx/m > sg18438.html If you can figure out the format and the configuration parameters from the above sources, I would greatly appreciate if you could write a bit of documentation and send a patch for Documentation/video4linux/omap3isp.txt.
