+Subject: [PATCH] net: allwinner: emac: Add missing free_irq
+
+The sun4i-emac driver uses devm_request_irq at .ndo_open time, but relies on
+the managed device mechanism to actually free it. This causes an issue whenever
+someone wants to restart the interface, the interrupt still being held, and not
+yet released.
+
+Fall back to using the regular request_irq at .ndo_open time, and introduce a
+free_irq during .ndo_stop.

+alias on all the sunxi SoCs with EMAC. In this way, people using

+U-Boot and Linux with no additional effort.

+Subject: [PATCH] ARM: sun7i: dt: Fix interrupt trigger types
+
+The Allwinner A20 uses the ARM GIC as its internal interrupts controller. The
+GIC can work on several interrupt triggers, and the A20 was actually setting it
+up to use a rising edge as a trigger, while it was actually a level high
+trigger, leading to some interrupts that would be completely ignored if the
+edge was missed.
