This series hooks up the GPIO controller found in some older X-Powers
PMICs. The main motivation is converting the U-Boot driver over to use
devicetree, but Linux might as well gain support for the hardware too.

Changes in v2:
 - Combine multiple "const"s in the binding into an "enum"

Samuel Holland (4):
  dt-bindings: gpio: Add AXP221/AXP223/AXP809 compatibles
  mfd: axp20x: Add AXP221/AXP223/AXP809 GPIO cells
  pinctrl: axp209: Support the AXP221/AXP223/AXP809 variant
  ARM: dts: axp22x/axp809: Add GPIO controller nodes
