+Subject: [PATCH] arm64: dts: allwinner: h616: Split Orange Pi Zero 2 DT
+
+The Orange Pi Zero 2 got a successor (Zero 3), which shares quite some
+DT nodes with the Zero 2, but comes with a different PMIC.
+
+Move the common parts (except the PMIC) into a new shared file, and
+include that from the existing board .dts file.
+
+No functional change, the generated DTB is the same, except for some
+phandle numbering differences.

+Subject: [PATCH] arm64: dts: allwinner: h616: Add OrangePi Zero 3 board
+ support
+
+The OrangePi Zero 3 is a development board based on the Allwinner H618 SoC,
+which seems to be just an H616 with more L2 cache. The board itself is a
+slightly updated version of the Orange Pi Zero 2. It features:
+- Four ARM Cortex-A53 cores, Mali-G31 MP2 GPU
+- 1/1.5/2/4 GiB LPDDR4 DRAM SKUs (only up to 1GB on the Zero2)
+- AXP313a PMIC (more capable AXP305 on the Zero2)
+- Raspberry-Pi-1 compatible GPIO header
+- extra 13 pin expansion header, exposing pins for 2x USB 2.0 ports
+- 1 USB 2.0 host port
+- 1 USB 2.0 type C port (power supply + OTG)
+- MicroSD slot
+- on-board 16MiB bootable SPI NOR flash (only 2MB on the Zero2)
+- 1Gbps Ethernet port (via Motorcomm YT8531 PHY) (RTL8211 on the Zero2)
+- micro-HDMI port
+- (yet) unsupported Allwinner WiFi/BT chip
+
+Add the devicetree file describing the currently supported features,
+namely LEDs, SD card, PMIC, SPI flash, USB. Ethernet seems unstable at
+the moment, though the basic functionality works.
