+Subject: arm64: allwinner: sun50i-a64: Add dt node for the syscon control
+ module
+
+This patch add the dt node for the syscon register present on the
+Allwinner A64.
+
+Only two register are present in this syscon and the only one useful is
+the one dedicated to EMAC clock.

+Subject: arm64: allwinner: sun50i-a64: add dwmac-sun8i Ethernet driver
+
+The dwmac-sun8i is an Ethernet MAC that supports 10/100/1000 Mbit
+connections. It is very similar to the device found in the Allwinner
+H3, but lacks the internal 100 Mbit PHY and its associated control
+bits.
+This adds the necessary bits to the Allwinner A64 SoC .dtsi, but keeps
+it disabled at this level.

+Subject: arm64: allwinner: a64: pine64: add missing ethernet0 alias
+
+The EMAC Ethernet controller was enabled, but an accompanying alias
+was not added. This results in unstable numbering if other Ethernet
+devices, such as a USB dongle, are present. Also, the bootloader uses
+the alias to assign a generated stable MAC address to the device node.
