+Subject: [PATCH 1/5] ARM: dts: turris-omnia: configure LED[0] pin function to
+ link/activity
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The marvell PHY driver changes the LED[0] pin function to "On - 1000
+Mbps Link, Off - Else".
+
+Turris Omnia expects that the function is "On - Link, Blink - Activity,
+Off - No link".
+
+Use the `marvell,reg-init` DT property to change the function.
+
+In the future, once netdev trigger will support HW offloading, we will
+be able to have this configured via the combination of PHY driver and
+leds-turris-omnia driver.

+Subject: [PATCH] ARM: dts: turris-omnia: enable LED controller node
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The LED controller node is disabled because the leds-turris-omnia driver
+does not support setting the LED blinking to be controlled by the MCU.
+
+The patches for that have now been sent [1], so let's enable the node.
