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.

Subject: [PATCH] ARM: sunxi: dt: add EMAC aliases
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
U-Boot uses the ethernet0 alias to locate the right node to fill in
the MAC address of the first ethernet interface. This patch adds the
alias on all the sunxi SoCs with EMAC. In this way, people using
ethernet in U-Boot (eg, for tftp) can keep a consistent address on both
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.
