Yep, for e.g we have wrappers for api's like gpio_request etc. The real problem, however, seems to be that we have been using a distro which uses kernel 2.6.24. It does not have the "<linux/gpio.h>" and the "<regulater/consumer.h> which export regulator_register_notifier()/regulator_unregister_notifier() functions. So, i will have to look into how to backport this. THe gpio lib thing may be straightforward but i am way ignorant on the regulator/pmic infrastructure. It would greatly help you can shed some light on the regulator part and if there is any quick way to get around to backport the regulator specific functions. Thanks in advance for your help! -Alfred.
