   4 Subject: [PATCH 46/90] ARM: dts: sunxi: Add AXP221 and AXP809 GPIO nodes
   5
   6 These PMICs each have two GPIO pins, and are supported by the axp_gpio
   7 driver. In order to convert the axp_gpio driver to probe using the
   8 device tree, the corresponding device tree nodes must be present. Add
   9 them, following the same binding as the AXP209 and AXP813.
