Subject[PATCH] arm64: allwinner: h5: add NanoPi NEO Plus2 DT support
Date
Add initial DT for NanoPi NEO Plus2 by FriendlyARM
- Allwinner quad core H5 Cortex A53 with an ARM Mali-450MP GPU
- 1 GB DDR3 RAM
- 8GB eMMC flash (Samsung KLM8G1WEPD-B031)
- micro SD card slot
- Gigabit Ethernet (external RTL8211E-VB-CG chip)
- 802.11 b/g/n WiFi, Bluetooth 4.0 (Ampak AP6212A module)
- 2x USB 2.0 host ports & 2x USB via headers

Changes
v1 -> v2
add wifi power controller, mmc1, mmc2
remove reg_usb0_vbus
v2 -> v3
fix typo s/orangepi/nanopi/, s/pus/plus/
usb_otg set to host mode
wifi fix, based on commit 442e1f7e brcm,bcm43xx-fmac.txt
remove functions on header pins: spi, ir, ehci 1&2, ohci 1&2, uart 1&2
remove hdmi, de2, r-gpio-keys, mixer - not supported the board
v3->v4 update WiFi chip compatible to bcm43430-fmac
v4->v5 back to bcm4329-fmac bcm43430-fmac is the wrong way.
v5-->v6
sorted nodes
removed usb0_id_det-gpios,boot_device, drive-strength = <40>; boot_device
delete nodes which are same as the defaults.
