arm64: dts: allwinner: h616: enable DVFS for all boards With the DT bindings now describing the format of the CPU OPP tables, we can include the OPP table in each board's .dts file, and specify the CPU power supply. This allows to enable DVFS, and get up to 50% of performance benefit in the highest OPP, or up to 60% power savings in the lowest OPP, compared to the fixed 1GHz @ 1.0V OPP we are running in by default at the moment.

arm64: dts: allwinner: h616: update emac for Orange Pi Zero 3 The current emac setting is not suitable for Orange Pi Zero 3, move it back to Orange Pi Zero 2 DT. Also update phy mode and delay values for emac on Orange Pi Zero 3. With these changes, Ethernet now looks stable.

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.
