OF_GPIO_ACTIVE_LOW is a Linux implementation detail. The binding document should be referring to GPIO_ACTIVE_LOW found in include/dt-bindings/gpio/gpio.h.

This means, the two properties are "superimposed," for example leaving the -OF_GPIO_ACTIVE_LOW flag clear and specifying the respective *-inverted +GPIO_ACTIVE_LOW flag clear and specifying the respective *-inverted property property results in a double-inversion and actually means the "normal" line polarity is in effect. -- 2.15.0 -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
