The Radxa A5E is a development board using the Allwinner A527 SoC, which
is using the same die as the A523 SoC, just exposing the pins of more
peripherals (like HDMI or the 2nd MAC). The board features:
- Allwinner A527/T527 SoC: 8 ARM Cortex-A55 cores, Mali-G57 MC1 GPU
- 1GiB/2GiB/4GiB LPDDR4 DRAM
- AXP717 + AXP323 PMICs
- Raspberry-Pi-2 compatible 40pin GPIO header
- 1 USB 2.0 type C port (OTG), also power supply
- 1 USB 3.0 type A host port (multiplexed with M.2 slot)
- 1 M.2 M-key 2230 slot, with 1 PCIe2.1 lane connected (multiplexed
with USB 3.0 port)
- MicroSD slot
- optional eMMC, 8, 16 or 32GB available
- optional on-board 16MiB bootable SPI NOR flash
- two 1Gbps Ethernet ports (via MAXIO MAE0621A PHYs)
- PoE header for optional supply circuit on one Ethernet port
- WiFi 802.11 a/b/g/n/ac/ax (LB-Link BL-M8800DS2 module using AIC8800)
- HDMI port
- camera and LCD connectors
- power supply via USB-C connector (but no PD) or GPIO header pins
This .dts describes the devices as far as we support them at the moment.
The PMIC rails have been assigned as per the schematics.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
