[PATCH v2 1/4] dt-bindings: gpio: Add AXP221/AXP223/AXP809 compatibles

[Samuel Holland <samuel@xxxxxxxxxxxx>]

These PMICs each have 2 GPIOs with the same register layout as AXP813,
but without an ADC function.

Signed-off-by: Samuel Holland <samuel@xxxxxxxxxxxx>

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