[PATCH 1/3] arm64: allwinner: h5: sort the device nodes in / part for some boards

[Icenowy Zheng]

The reg_vcc3v3 node is wrongly placed at the start of the / part, but
not with other fixed regulators used by the board, which makes the
device nodes unsorted.

As Orange Pi Prime and Nano Pi NEO2 device trees are copy'n'paste works,
they share the device node unsorted issue.

Fix this by move reg_vcc3v3 node to the position before reg_usb0_vbus.

[PATCH 2/3] arm64: allwinner: h5: enable dwmac-sun8i for Orange Pi Prime

[Icenowy Zheng]

Add the required DT parts to enable Ethernet (dwmac-sun8i driver) on
the Orange Pi Prime board. It uses an external Realtek RTL8211E PHY
connected via RGMII to provide GbE network.

This includes the regulator (which is controlled by a GPIO pin) and
the actual Ethernet MAC node, referring the RGMII pins of the device.

[PATCH 3/3] arm64: allwinner: h5: enable dwmac-sun8i for Nano Pi NEO2

[Icenowy Zheng]

Add the required DT parts to enable Ethernet (dwmac-sun8i driver) on
the Nano Pi NEO2 board. It uses an external Realtek RTL8211E PHY
connected via RGMII to provide GbE network. Specially unlike other
Allwinner boards, the phy is connected to MDIO address 7, not 1.

This includes the regulator (which is controlled by a GPIO pin) and
the actual Ethernet MAC node, referring the RGMII pins of the device.
