+Subject: ARM: dts: turris-omnia: describe switch interrupt
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Describe switch interrupt for Turris Omnia so that the CPU does not have
+to poll the switch. We also need to to set mpp45 pin to gpio function
+for this.
