Subject: [PATCH v5 0/7] max8903: Add device tree support and misc fixes

From: Chris Lapa <chris@...a.com.au>

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


Chris Lapa (7):
  max8903: adds documentation for device tree bindings.
  max8903: store pointer to pdata instead of copying it.
  max8903: cleans up confusing relationship between dc_valid, dok and
    dcm.
  max8903: adds requesting of gpios.
  max8903: removes non zero validity checks on gpios.
  max8903: remove unnecessary 'out of memory' error message.
  max8903: adds support for initiation via device tree
