[PATCH] dt-bindings: power: Correct interrupt flags in examples

[PATCH] dt-bindings: power: Correct interrupt flags in examples

[Krzysztof Kozlowski]

GPIO_ACTIVE_x flags are not correct in the context of interrupt flags.
These are simple defines so they could be used in DTS but they will not
have the same meaning:
1. GPIO_ACTIVE_HIGH = 0 = IRQ_TYPE_NONE
2. GPIO_ACTIVE_LOW  = 1 = IRQ_TYPE_EDGE_RISING

Correct the interrupt flags, assuming the author of the code wanted some
logical behavior behind the name "ACTIVE_xxx", this is:
  ACTIVE_LOW => IRQ_TYPE_LEVEL_LOW

Hi Rob,

Did you mean Acked-by or are you taking this patch directly?

Best regards,
Krzysztof
