[PATCH 1/3] dt-bindings: add vendor prefix for Lichee Pi

[PATCH 1/3] dt-bindings: add vendor prefix for Lichee Pi

[Icenowy Zheng]

Lichee Pi is a new "Pi"-named development board series.

Currently available device, Lichee Pi One, is by only one person as
night job, so the device series name is chosen to be the vendor prefix.

[PATCH 3/3] ARM: dts: sun5i: add support for Lichee Pi One board

[Icenowy Zheng]

Lichee Pi One is a low-cost Allwinner A13-based development board, with
an AXP209 PMU, a USB2.0 OTG port, a USB2.0 host port (or an onboard
RTL8723BU Wi-Fi card), optional headers for LCD and CSI, two GPIO
headers and two MicroSD card slots (connected to mmc0 and mmc2, both
bootable).

Add support for it.
