Subject: [PATCH 01/39] ARM64: dts: meson-gxm: Add support for Khadas VIM2
|
|
|
|
The Khadas VIM2 is a Single Board Computer, respin of the origin
|
|
Khadas VIM board, using an Amlogic S912 SoC and more server oriented.
|
|
|
|
It provides the same external connectors and header pinout, plus a SPI
|
|
NOR Flash, a reprogrammable STM8S003 MCU, FPC Connector, Cooling FAN header
|
|
and Pogo Pads Arrays.
