Subject: arm64: dts: add Pine64 support
|
|
|
|
The Pine64 is a cost-efficient development board based on the
|
|
Allwinner A64 SoC.
|
|
There are three models: the basic version with Fast Ethernet and
|
|
512 MB of DRAM (Pine64) and two Pine64+ versions, which both
|
|
feature Gigabit Ethernet and additional connectors for touchscreens
|
|
and a camera. Or as my son put it: "Those are smaller and these are
|
|
missing." ;-)
|
|
The two Pine64+ models just differ in the amount of DRAM
|
|
(1GB vs. 2GB). Since U-Boot will figure out the right size for us and
|
|
patches the DT accordingly we just need to provide one DT for the
|
|
Pine64+.
|
|

|
[Maxime: Removed the common DTSI and include directly the pine64 DTS]
