This API is going to be used to configure some pins that are protected for simple modification.
It's not a comprehensive pinctrl driver but can be turned into one when we need this in the future. Now it is planned to be used only in one place. So that's why I decided not to pollute the codebase with a full-blown pinctrl-merrifield nobody will use.
This driver reads corresponding fields in DT and configures pins accordingly.
The "protected" flag is used to distinguish configuration of SCU-owned pins from the ordinary ones.
The code has been adapted from Linux work done by Andy Shevchenko in pinctrl-merrfifield.c

Please can you use the livetree API (dev_read_...)?
Regards, Simon
Sure. Will do. It will need CONFIG_OF_LIVE=y for edison_defconfig to be set. Is there any other modifications or possible regressions that I need to take into account? Or if I just stick to doc/driver-model/livetree.txt things should go smoothly?
