+/* GPIO_DS_* are for pin drive strength configuration.
+ *
+ * The drive strength of individual pins can be configured
+ * independently for when the pin output is low and high.
+ *
+ * The GPIO_DS_*_LOW enumerations define the drive strength of a pin
+ * when output is low.
+
+ * The GPIO_DS_*_HIGH enumerations define the drive strength of a pin
+ * when output is high.
+ *
+ * The DISCONNECT drive strength indicates that the pin is placed in a
+ * high impediance state and not driven, this option is used to
+ * configure hardware that supports a open collector drive mode.
+ *
+ * The interface supports two different drive strengths:
+ * DFLT - The lowest drive strength supported by the HW
+ * ALT - The highest drive strength supported by the HW
+ *
+ * On hardware that supports only one standard drive strength, both
+ * DFLT and ALT have the same behaviour.
+ *
+ * On hardware that does not support a disconnect mode, DISCONNECT
+ * will behave the same as DFLT.
