OLimex A64-OLinuXino is an open-source hardware board
using the Allwinner A64 SOC.

OLimex A64-OLinuXino has
- A64 Quad-core Cortex-A53 64bit
- 1GB or 2GB RAM DDR3L @ 672Mhz
- microSD slot and 4/8/16GB eMMC
- Debug TTL UART
- HDMI
- LCD
- IR receiver
- 5V DC power supply

Signed-off-by: Jagan Teki <jagan@amarulasolutions.com>

Changes for v3:
- Droped i2c1, not found on schmatic
- Updated vddfb-cpux regulator volt range 1.04 ~ 1.3 V
- Removed poly-phased DCDC3 regulator node and added comment
- Update DLDO4 regulator name as vcc-wifi-io
- Moved uart0 below regulators
Changes for v2:
- Tested on board
- Added AXP803 regulator
