52 # controllers line polarity properties, we have to fix the meaning
55 # low." Therefore, using the "cd-inverted" property means, that the
56 # CD line is active high, i.e. it is high, when a card is
57 # inserted. Similar logic applies to the "wp-inverted" property.
60 # ways: as GPIOs, specified in cd-gpios and wp-gpios properties, or
