+Subject: [PATCH] overlays: audremap: Support GPIOs 18 & 19
+
+PWM audio can also be used on GPIOs 18 and 19, so add the pins_18_19
+parameter to select that location. pins_12_13 explicitly chooses GPIOs
+12 and 13, although this is the default behaviour so is there only for
+completeness.
+
+See: https://github.com/raspberrypi/firmware/issues/1178
