This patch set adds device tree support for the MAX8903 battery charger.
It also cleans up logic with dc_valid, dok and dcm pins as well as
fixing up validity checking of gpios.
I verified these patches work on a board I have here, which uses the
DC power side (not the USB portition) of the MAX8903.
Changes v4 -> v5:
* Changes compatible field from max8903_charger to max8903 in 1/7 and 7/7
* Improves DT documentation to include direction and state for each gpio
Changes v3 -> v4:
* Fixed formatting, such as multiline strings and indentation mistakes
* Moved gpio setup code into max8903_setup_gpios() in 3/7
* Fixed typo in 5/7
* Renamed of_node to np in 7/7
Changes v2 -> v3:
* Separate requesting of gpio's into its own commit
* Fixed up validity checking of GPIO's
* Remove dc_valid and usb_valid from device tree
* Remove some unncessary init to psy_cfg.num_supplicants and psy_cfg.supplied_to
* Reorder patches so device tree implementation is final patch
Changes v1 -> v2:
* Separate DT bindings documentation into its own commit
* Add maxim prefix to DT compatible field
* Add gpios suffix to gpio's in DT
* Remove malloc failed error message
